Finally made the decision to go ahead with the IB build after thinking it over for a long time. The car is a 2008 Chevy Impala and the back seats do not fold down so the front of the baffle doesn't need to be pretty, just functional. Thanks to the guys over on diyma for the great info and the little push I needed to make this happen. For the most part this is just going to be a slew of pics without a lot of descriptions. Please feel free to ask any questions you like and keep in mind this is not 100% complete yet.

It all started with this piece of cardboard. Got my baffle size down with this:

Panels cut for the baffle:

Cutting out the holes for the subs:

Getting ready to laminate the layers together:

Two become one:

Shot of the open area on the sides of the baffle that I need to enclose to help seal the baffle to the car:

Shot showing how tight the baffle fits at the top against the rear deck:

Side pieces cut and attached to the main baffle:

Little notch I had to sand into the baffle to fit over a funny little hump in the trunks floor :

I'm an idiot LOL. Guess I should add that. Its a 2008 Chevy Impala and the seats do not fold down so the baffle won't be pretty at all up front. Just functional

Thinking about taking the IB plunge. All IB users please chime in - Car Audio | DiyMobileAudio.com | Car Stereo Forum (http://www.diymobileaudio.com/forum/general-car-audio-discussion/163140-thinking-about-taking-ib-plunge-all-ib-users-please-chime.html)

For anybody who can't wait and is interested in my original thread and all of the pics you can check the install out over on diyma.

Never answered your question about the subs. They are Phoenix Gold Ti2 15's. Similar to the old pg rsdc subs but they don't sound as good lol.

I will help with any IB questions you have but this is my first shot at it. There are several guys over on diyma who are very knowledgeable on IB installs.

Thanks sir. I have semi finished pics of it I will post shortly. This install took about two weeks and I only had two hour blocks here and there to work on it and get the seats back in the car so I could cart the kids around the next day. Its one of the more involved installs I have done and its not completely done yet. I will probably only deaden whats necessary in the trunk. Subs are Phoenix Gold Ti2 15's. They aren't my favorite but sound much better in this alignment than any other way I have used them. The subs will be swapped out but the install is staying

More pics :

Baffle sanded up a bit after attaching the side pieces:

http://i664.photobucket.com/albums/vv10/jsb4251981/Mobile%20Uploads/20140517_131207_zpsmmlddd15.jpg (http://s664.photobucket.com/user/jsb4251981/media/Mobile%20Uploads/20140517_131207_zpsmmlddd15.jpg.html)

Another test fit. You can see where the little notch fits over the ridges in the trunk floor:

http://i664.photobucket.com/albums/vv10/jsb4251981/Mobile%20Uploads/20140517_131955_zpsiwtc8ibc.jpg (http://s664.photobucket.com/user/jsb4251981/media/Mobile%20Uploads/20140517_131955_zpsiwtc8ibc.jpg.html)

Here you can see I have a gap on either side of the baffle that needs to be taken care of:

http://i664.photobucket.com/albums/vv10/jsb4251981/Mobile%20Uploads/20140517_132543_zpsz7in0olk.jpg (http://s664.photobucket.com/user/jsb4251981/media/Mobile%20Uploads/20140517_132543_zpsz7in0olk.jpg.html)

Here I have a piece of wood cut to size that will bolt to the car and be attached to the sides of the baffle. Just a dry fit here:

http://i664.photobucket.com/albums/vv10/jsb4251981/Mobile%20Uploads/20140519_181438_zpspiqgbomw.jpg (http://s664.photobucket.com/user/jsb4251981/media/Mobile%20Uploads/20140519_181438_zpspiqgbomw.jpg.html)

Here you can see that I have a nice gap on the side of the baffle. The side piece will not lay right because of the little indentation in the sheet metal from the top most hole in the pic:

http://i664.photobucket.com/albums/vv10/jsb4251981/Mobile%20Uploads/20140519_181455_zpsglhbflbw.jpg (http://s664.photobucket.com/user/jsb4251981/media/Mobile%20Uploads/20140519_181455_zpsglhbflbw.jpg.html)

Quick little mod I did to get the board to lay flat. Used a 1.25" spade bit to make "slots" in the wood to get around the indentation in the sheet metal:

http://i664.photobucket.com/albums/vv10/jsb4251981/Mobile%20Uploads/20140519_183139_zpsrtl1blhz.jpg (http://s664.photobucket.com/user/jsb4251981/media/Mobile%20Uploads/20140519_183139_zpsrtl1blhz.jpg.html)

Here the side piece is tacked in and fitting much better:

Both sides tacked in and fitting much nicer:

Quick little shot of the 2x4 brace that will be attached to the back side of my side pieces that the baffle will eventually be screwed into:

Original center baffle brace. This ends up getting modded a bit:

Lame pic showing a hole actually drilled into the sheet metal for bolting the baffle in :

Corresponding holes drilled in the baffle :

Another test fit so I can see if all my holes line up and they do. Also here you can see the side boards are bolted in . I used butyl tape between the wood and the sheet metal to avoid any rattles:

http://i664.photobucket.com/albums/vv10/jsb4251981/Mobile%20Uploads/20140520_193405_zpsoi5taht7.jpg (http://s664.photobucket.com/user/jsb4251981/media/Mobile%20Uploads/20140520_193405_zpsoi5taht7.jpg.html)

Just a pic here showing how good of a fit I have on the sides . Baffle is only tacked in with 1 screw on each side. With just these two screws installed I can grab the baffle and shake the entire car with minimal movement of the baffle itself. :

Nice glue bead laid down for attaching the revised center brace. Notice the notch in the bottom of it. This will allow it to sit over the ridges in the trunk floor and allow me to attach it to the trunk floor:

Spray glue laid down for carpeting the only visible part of the baffle:

Weather stripping laid down where the baffle will meet the rear deck. Also get a good shot of the 2x4 braces mounted to the side boards:

http://i664.photobucket.com/albums/vv10/jsb4251981/Mobile%20Uploads/20140527_180624_zps55atf0hl.jpg (http://s664.photobucket.com/user/jsb4251981/media/Mobile%20Uploads/20140527_180624_zps55atf0hl.jpg.html)

Baffle forced into place. With the trunk carpet back in I literally had to climb into the trunk and kick the baffle into place. Bolts in the baffle and ready to be tightened:

http://i664.photobucket.com/albums/vv10/jsb4251981/Mobile%20Uploads/20140527_182404_zpsbwrlvrbi.jpg (http://s664.photobucket.com/user/jsb4251981/media/Mobile%20Uploads/20140527_182404_zpsbwrlvrbi.jpg.html)

Quick shot showing two of the five bolts I used to bolt the top to the car. All out of the way of the back seat and tightened up:

Three heavy duty wood screws on each side attach the sides of the baffle to those 2x4 braces you saw earlier(which are also bolted to the car) :

Weather stripping around the holes where the seat locks in. I can't totally seal these off but need to do the best I can:

One sub installed:

Both subs installed and a view of the brace secured to the floor with steel brackets that are bolted to the brace . The steel brackets are held to the floor with industrial grade epoxy. This stuff will not move unless I need it to. I cannot bolt through the floor here because the gas tank is right underneath :

Both subs installed from back. Please excuse the wiring job. I had about two minutes to get this wired after getting everything in the car and putting it back together:

Thats all my pics for now. A lot of stuff I did not get pics of. Mostly sealing nooks and crannies with tape,deadener,foam,etc. Lots more sealing to come and a new set of subs at some point. For now I am real satisfied with it. Plenty of output and real quick and punchy. Sounds great with just about everything. Hits some crazy lows. It isn't the loudest setup I have ever had but it has enough output for me and takes up little space. I do not care for these subs but they sound the best I have ever heard them sound in this alignment so I know it has potential. After I get it all sealed I will start the search for different drivers but these will do for now. Next step of the install is an amp and battery rack flushed into the side wall of the trunk which once complete will leave me with almost all of my trunk usable .

How's it sound? Have you tested yet

It sounds great to me. I have tried a ton of different subs in a ton of different ported/sealed enclosures and no matter what in this car it seemed like I either had low lows or that nice upper bass kick but with this setup I can play just about anything and after I installed a larger amp today they really came alive output wise and are sounding much better than when I first fired them up. I guess my old school Kicker Impulse 1252xi just wasn't a good match for these subs. Using an MTX Thunder 2300x bridged onto the pair of subs I now have about as loud of a setup as I ever had in this car without giving up my whole trunk to do it or using 2K worth of amps. As long as I can run IB I don't see a reason to do it any other way in my daily driver.

It sounds great to me. I have tried a ton of different subs in a ton of different ported/sealed enclosures and no matter what in this car it seemed like I either had low lows or that nice upper bass kick but with this setup I get both of those and after I installed a larger amp today they really came alive output wise and are sounding much better than when I first fired them up. I guess my old school Kicker Impulse 1252xi just wasn't a good match for these subs. Using an MTX Thunder 2300x bridged onto the pair of subs I now have about as loud of a setup as I ever had in this car without giving up my whole trunk to do it or using 2K worth of amps. As long as I can run IB I don't see a reason to do it any other way in my daily driver.

so how much power to them right now?

Currently running about 800-1000 watts to them not figuring in impedance rise. Believe me I would love a one amp solution but I don't think the jbl has enough ooomph on the sub channel to keep me happy. The kicker amp I was using was approximately 500 rms but its a total night and day difference between the kicker and the MTX I have in there now. Shouldn't really be that big of a difference sonically but my ears tell me otherwise.

I would like to try that JBL though....... I have a feeling it is underrated on that sub channel. Just need expendable cash

that's a lot of power. Maybe I should keep my 3 ms-a5001 instead of going off the ms-a1004 for powering the GTi. One more question, what kind of bolt/screws do you use to screw into the sheet metal of the car?

I didn't use any screws into sheet metal. I used 1/4-20 thread 2.5" long bolts for the top of the baffle and 1/4-20 2" long bolts for the side panels. I used a 1" OD fender washer on the back side of the baffle (the visible side) and 5/8 OD flat washer,1/4 lock washer,and nut on the other side to hold it to the car. I suggest stainless steel fasteners but zinc coated should work too as long as its in the car and not exposed to the elements. In other IB build logs I have seen people using self tapping sheet metal screws to secure the baffle to the car but if you have solid points to bolt to there is no good reason not to bolt your baffle in IMO.

I've seen a few IB's in my day. Definitely great sound and wide bandwidth but the compromise is output. If you build it right you'd definitely be happy if you found some drivers that were better quality with some modern technology and more suited to that alignment.

I was worried about output at first. I have been told that essentially its the same output potential as sealed with much better efficiency and that seems to be pretty accurate . This pair gets plenty loud for me. I do plan on finding some better quality drivers though now that I know this will work. I had these laying around and decided to give them a shot

Indeed, once it's tight and solid it's essentially a 20 cube+ sealed box.

So I knew that I had some holes lurking underneath the rear deck carpeting and trim so I tore everything apart this weekend and found some gaping holes!!!!

http://i664.photobucket.com/albums/vv10/jsb4251981/Mobile%20Uploads/20140531_134632_zpsvgqxelwq.jpg (http://s664.photobucket.com/user/jsb4251981/media/Mobile%20Uploads/20140531_134632_zpsvgqxelwq.jpg.html)

There was a hole this size on either side towards the front of the rear deck and in the back two even larger holes. Didn't get any pics of how I sealed them up but it was all deadener and man did it make a difference. Bass is a lot tighter and has more punch/kick than it did previously. I am really liking this IB thing :D

Thanks sir. Functionally it is almost where I want it. The rear deck itself flexes like crazy on low notes so I would like to find a way to stiffen that up but other than that I am pretty well sealed. I am still debating on whether or not to do a little trim panel around the subs/baffle. I don't think it looks bad now but it could be prettied up a little. After that I need to make myself an amp/battery rack that tucks into the side of the trunk

yep, looks good.

note you can reverse the subs and gain even more trunk space, have the aesthetics of the sub cones, and not sacrifice output.

Thanks man. Means a lot coming from you. The original plan was to have the cones in the trunk but these were just a touch too deep. The magnets were just hitting the back of the seats. The look of the motors is kind of growing on me though but I would like a little extra space too. I plan to change drivers and am hoping I can find something with just a little bit shallower mounting depth so I can have the cones facing into the trunk

i like your attention to detail with getting the mounts made, shaving where necessary, making separate parts where necessary, etc.

i know people think you lose low end with IB but i've had the opposite - unlimited low frequency response, well below 20Hz

Thanks again. It definitely helped me to do this build a little at a time . It gave me time to take pics and sit back and think about different issues and how to tackle them. Just cramming it all in there at once would have been a huge mistake and probably left me unhappy with the result. In the end all the work was worth it and I hope the pics can help other people get ideas about their own builds.

Everything that concerned me about the sound of an IB install has been a non issue. I was worried about output and bandwidth big time and my assumptions about IB couldn't have been any more wrong. I have plenty of lows and can hit notes with authority I never have with traditional enclosures and I can play any type of music I care to listen to and hit just about every note without missing a beat.

So anybody here on this forum that really knows me should know I am that guy that needs to change things up even when I am happy. The Phoenix Gold subs didn't really do it for me at first but after a few little tweaks were sounding much better. But I still wanted something else. A different sound. I am sure I will get some chuckles for this but based off of the recommendation of some of the SQ guys on DIYMA and my very small budget at the time I went with a pair of Pyle (yes Pyle) Blue Wave 15's. Yes they are cheap and cheesy looking but in an IB setup these things are very smooth sounding. Not as loud as the PG subs but overall much nicer sound ( I never thought I would say that)

In the top pic of my last post you can see my temp amp install. I had my heart set on a 5 channel and when I saw the Hifonics zxi60.4+1K that cookboy ; had posted I had to have it. He gave me an awesome deal on it and after replacing some rca's,a switch , and making some mounting feet it was good to go.

Sure its not the greatest 5 channel out there but for the money invested its a champ. Sounds as good as anything else I have had in my install and is everything I need in one chassis. The amp install is still far from done but even the single amp helps clean things up a bit

So the Pyle's sound so much better than you'd expect but I still was curious and I had this Dayton Audio Titainic MKIII 15 laying around . So in she went

I just fabbed up a little board to cover up the hole from the other sub and threw this one in. Initial impression is that the upper bass is not nearly as loud and clear as either set of 15's I previously ran . Not even close . But the lows are pretty **** close in output to what I had with the Pyles and buttery smooth. I don't hate how it sounds but the Pyles sounded better overall than this Dayton does. They will most likely make their way back into the install unless I can find something else to try

I've heard that the Blue Waves are surprisingly good for IB usage. There's always the Acoustic Elegance IB-AU and the Fi IB3 if you feel like you want something that will handle more power.

I was real surprised at how good they sounded. Have I had louder setups? Absolutley. More musical with good output ........ I don't think so. I've spent a lot of money and built a lot of different boxes trying to get that prefect sound. That sound I remember from back in the day. IB gives me that sound that I missed and although its not as loud as some ported setups I could care less. Much more enjoyable to listen to. The Pyles sounded pretty good with everything. Their only limit was xmax/output. Other than that they were IB champs. I have my eye on a pair of acoustic elegance IB 15's on Diyma. Real expensive but I have heard they are worth every penny. I also heard JBL GTO's and Boston Acoustics G2's are real nice as well.

glad to see you got the amp working again. it really was a great budget 5 channel amp.

Well I have heard that if it's good for sealed it will be even better IB but I can say from my own experience that what I heard is not always true. Case in point I had the Dayton Titanic MKIII sealed and it sounded great to me and is known to be a great sealed box driver. Almost everything I could want (almost). I tried it IB and although it didn't **** it wasn't great either. Kinda like a bad ported box . All lows and no upper bass kick or punch. Overall the cheapy Pyles are a much better sounding sub IB or TB (trunk baffle) . Sure they don't have the throw or build quality of the Dayton Titanic but in IB/TB its a no brainer and honestly the build quality on the Pyle subs I used is not bad at all. From what others say subs with high Qts values ,low Fs values, and high Xmax values are very desirable for IB use

On another note today I was able to see in person (and in turn purchase) the Dayton Audio IB 15". Way more throw than the Pyle subs and in general feels like a real quality built driver and purpose built for IB installs. I have not installed them yet but I expect great results. The suspension isn't "loose" but is a bit softer than most drivers which in my experience the softer suspension drivers are almost always better sounding drivers although they sacrifice some power handling. I am willing to trade that power handling though for the efficiency and effortless sound an IB setup provides
