I guess Ill throw together a build log for my 95 mustang. Its had a couple different setups, some in the trunk and even got bored one day and decided to wall it off... lol

I really dont have a huge amount of creativity so any input would be great. Anyway for equipment I am running a single 12" fully loaded BTL, off a planet audio 2250D one of the older ones. ummm a Kenwood headunit with the usb plugin. A ****** amp to run the front speakers (trying to give them around 100 rms or so a piece) and some ****** speakers in the front. lol I was on parts express and ran into PYLE PRO SOUND DRIVERS WWWOOOOOHOOOO and picked em up for 13 bucks a piece figured why not. They get loud which is what I wanted, and handle alot of power, and noone will see them, and I try my best not to let the secret out but for the price why not I would actually recommend them to budget minded people. Oh and some temporary alphasonik tweeters that I had lying around because I blew the mids to go with them.... oops.

yeah I know this thread just keeps getting worse. You walk in looking to find a nice mustang with nitrous and a loud system.... and you get pyle.

I am running a 250 amp load boss alternator which so far is doing really well. Some optima batteries and Knu wire and alot of audiopipe wiring acessories. I went cheap on sound deadener, Fatmat and so far I have no complaints but used 100 sq feet so far and I think im gonna order another 50 to go over some spots to hopefully make the car a little quieter on the highway.

As for the build I started off by deadening the trunk and wheel wells, floor and doors and quarter panels. One of my main goals was to try to quiet down the drone from the flowmaster exhaust that dumps under the car. I do wish I would have spent a little more on deadener but oh well. Heres the first pic. Dont mind the car it needs some paint.... but not as bad as the pics make it look. I have been cutting/building everything in the same garage as the car is in so its COVERED in mdf dust.

After deadening I threw together a frame for the false floor in the trunk. I also needed to make the floor a little bit taller to fit a battery in the spare tire area. I decided that I would try to be creative and put a plexiglass window in the trunk floor to "show off" some of the electronics. you can see parts of it in this next pic but its nowhere near completed. its just part of the frame of it, theres alot more to it, and I have only cut half of the floor. I got a little excited to see some progress.

and once again the window is just sitting there, it will be flush with the floor in the end.

Ummmm I think theres a limit as to how many pics I can post in one ummm post lol so I think Im gonna start another one... lol

Well... I'm not so big on the equpiment, but in the end if it makes you happy an you know whats what then it's all good. I like the craftsmanship tho, and the false floor is cool, who says you have no imagination. You should put some neon down there too... just kind of hidden so all you see is the glow... that would look really cool. Anyways goo luck, and I'd like to see how this turns out. Maybe you can change some peoples opinions about pyle, and boss, and alphasonik

hmmm I guess I should mention something about the box size and tuning... its 2.6 cubes tuned to 40 hz. Its a little high for my liking, I tend to listen to alot of chopped and screwed stuff. The last box I had it in was tuned LOW I had it metered and the person that was doing it told me I peaked at 44 hz or something, I told him that it didnt sound right and when I was only doing an amazing 138 DB I knew something was wrong. I asked if I could screw around and play some stuff he said sure. so I went into the hard drive and tried some slowed down jeezy, which was something like 28 hz and the guy turned around and gave me a funny look and reset the meter, aparently I was really peaking at 27 hz. It ended up doing a 145.4 at the dash with the driver window down. So this time I am hoping to do alot higher of a number but it sounds like an 8" sub on that same slowed down song lol. That box was originally for a 15" sub and was around 6 cubes so its alot different now. wow Im rambling alot....

anyway heres a pic of a door with my amazingly cool pyle speakers....

lol as much as I dont like neons and blinky lights and stuff there are some red strobe lights that are going in the floor plexiglass thing, but hidden so you cant actually see them.... which doesnt sound right lol... Im sure you can figure it out. lol along with some fuse holders with voltage gauges and some crossovers or something im not 100% sure yet. I really dont like the equipment either. however so far everyone who heard the setup before I pulled it out and started rebuilding have been suprised at the off brand front speakers and how they sound and not all sounding really harsh or distorting... Same thing with the fat mat, so far its been on for a month in florida sun, and its a black car and no issues.

Heres the alternator and a little bit of the motor

What was your last box tuned to???

lmao according to The RE audio box calculator it was tuned to 27 hz which just so happened to be what it peaked at and that was on a TL. The guy let me try a legal meca score I believe... the one at the headrest and again at 27 hz it did a 145.2 driver door wide open. When I designed the box it was late and I butchered the length of the port which was why it was so low.

And because of the size of the box and tuning it ****** at just about every hz above 32 or so. It basically it played low bass and absolutely nothing else.

Hmmmmmm I guess the nitrous bottle will be mounted on the right side of the trunk and I have another battery that will be mounted on the left out in the open or something. Im still not 100% sure how I want to finish everything. I will probably just carpet it all or something....

Heres a couple pics of the car, it has different rims on it now, in the pic from the track, I threw my slicks on it.

The front rims are whats on it now, the fronts are 9 inches wide the rears are 10.5

I was just curiou because That just seemed like it was small and high for a BTL, but I can't really knock it since I've never heard a BTL tuned like that, hope it goes well, and i totally understand what u mean about hidden strobes... thats how me and my friends talk too, so it makes perfect sense to me. This'll be a lot cleaner than my install, I just have **** laying around until I get around to making racks for my other amp and my crossover... lol, vids of it raping a 40 HZ tone when u finish... **** sounds painful

I have only heard one other car with a btl, it wasnt actually a car it was an expedition I believe and it didnt have a BTL it had 4 18" btls.... lol it was tuned low too. I pretty much followed what was recommended by FI as far as the box goes, port area and size, I just aimed a little high for tuning, I may try a slightly larger boxin the future... or maybe tune this one lower a bit.

40 hz really isnt all that impressive, I liked playing the 27 hz stuff and shaking the hell out of ****. flex for a single 12 was nuts! One of my managers at work said it sounded like a helicopter was outside with the way it sounded. Im going to bed now gotta work on it tomorrow.

not bad,as a mustang owner I cant place 200 lbs or more of car audio in the trunk because it
will deteriorate the cars balence and handeling.......

Looks like it is coming along and wootz for another person not having bad luck with the fatmat. I also use that mixed with my expensive SS product, lol! Going to put that on the doors here in the next month, so with that said. Does it help on the doors for your midbass? I imagine with the Plye mids it must be helping them sound better. I have the PG Rsd's and don't have much midbass, so going to deaden my doors, which I was going to do anyway, just being lazy, lol! Anyway, did you run those before with out deadener and could you tell a difference?

Nice car, nice setup, although not sure either if I would put all that weight in my car I take to the track from time to time.

My original plans were to make something I could take out whenever I needed to but that makes things difficult and the car is my DD. I also have a dedicated weekend/track car, its a Turboed 68 mustang that Ive owned since I was 12.

As for the midbass question they do sell some pyle pro speakers specifically for midbass, where mine are classified as midrange and they really dont have much. lol but so far they sound the best out of any speaker I have had in there. I dont think they are bad for a 5 inch speaker.

This morning I did some more work on the floor and finished the top of the floor... well I cut it all out, its still not permanant. I got half of it cut out for the plexiglass enclosure. I took some more pics of the floor frame and a picture of my new jigsaw that I picked up. I used to have a cheap black and decker bright *** orange one, and it finally took a crap on me so I went to home depot and picked up this dewalt that was on clearance. It really doesnt have alot of fancy features however it feels solid and the blade doesnt tilt when cutting and over all I would recommend it. heres a pic of that:

and ummm the floor nothing is screwed or glued at this point.

This morning I got the other half of the cloor cut out for the window thing and temporarily mounted the enclosure. its full of sawdust and stuff so its really not much to look at but when I finally got it in the floor on its own I stood back and it made me smile... lol

heres some pics:

The enclosure is in and the fuse holders are sitting on top. It looks like there are a bunch or really ****** cuts or something but its a bunch of stray marks from my marker

Wow I like the fake floor. I am going to mimic your set up on the floor. I have been trying to figure out what to do with the extra room where the spare tire is supposed to be. I like the idea of putting my amp in that space. I would like to build a box, actually 2 boxes. I have a 2002 gt and I would really like to install 2 subs like they do on the mach1000 system. That way I could still get use of trunk space and also access the trunk from the rear seat which I cannot now.


I would recommend getting a battery box from summit or steeda or something or make one. you seem to be pretty handy. It would clean up the rest of it.

check my install and stang out if you want.

instead of putting the fuse holders on top of the glass, or anything like that, I would either put them next to the red top or under neath the plexi.

Nice build.

I have a 94 Black Mustang GT, looks almost exactly like yours.


I had a 12in Q and a Sundown SAZ1500d.



A little advice, my car did better with sub back/foward and port to the side.


Regardless, nice.


Also, try put the battery on the other side where the bottle is at, seems to do better as far as weight transfer goes.

Your going to want to point the bottle straight back when your on the giggle gas... it ***** to run out if N2O before the trap

I have a 2002 GT that I'm about to do a build in, and that false floor is really cool. Yeah I think after seeing that my spare tire has got to go! Who needs a spare tire when you got AAA anyway? Sure, tow my ugly *** 50 miles for a flat tire, I don't care, don't cost nothin' :p:

woah this thing came back from the dead. I guess ill update you guys a little. I couldnt for the life of me get it any louder than that 145 @ 27hz I tried a smaller box and tuned it higher, it sounded much better but went down to a 143 @ 38 or so. so I tried a bigger box again and tuned it a little higher and did a 143 @ 39 hz. The only thing that that both of the lower scores had in common was that they had more port area so I was in the process of making another box with less port area however I broke the tinsel leads, so I never finished it. A couple days later I went to the track and ran a 12.80 and I guess I lost interest in having the loud system. I was pretty excited to break 12's without touching anything on the inside of the motor. still running stock bottom end, stock head, stock cam. Still not fast or anything but its a pretty good beater daily driver.

I now have the bottle mounted on the bottom portion of my rear seat delete along with the amp for my component speakers. I am having the sub fixed now so I may throw it back in there.

That's a nice install. My dad used to have a 95 Cobra but he sold it because he didn't want to deal with the electrical issues it was having. I told him I wanted it but he sold it anyway. :( Last year of the 5.0 too.

nice idea on the false floor man. I have a mustang too. And so does my brother. I have a 12" fi Q in mine and my brother has a 12" type-r in his.
