View Full Version : 300C SRT Build Getting Close. Door baffles done PICS

07-11-2008, 03:11 AM
300C SRT8 Silver

Stock Nav deck with PAC audio LOC
Dynaudio 360 (8", 4", 1.1" tweeter and passives) installed in doors, and kick panels
Image Dynamics 10" subs infinite baffle rear deck
Zapco DRC digital amp controller
Zapco DC650.6 Digital amp with crossover, 10 band eq and way more than I can tune.

Got the doors done. Or should I say door... I had installed the whole system and decided to change the Dynaudio 6.75" to the 8" model for more midbass. The MW160 sounded very good I assume these will only sound better. Gotto love the 3" voice Coil.

The object with the door install was to get the door as solid as possible. The door was dynamatted previously but now I upgraded from 6.75" speaker to a 8" driver. These speakers are a full 8" across Dynaudio MW170 (there is a 4" and 1.1" in the kick panels with crossovers).

First I wanted an angle (like the factory baffle), I wanted the speaker out a lil from the door (to fit the large magnet) and I wanted it solid as a rock. This angled baffle I made is basically 2 pieces of 3/4" MDF with some 1.25" wood legs on the bottom to make an angle. I filled the open areas in the wood with foam and I added layers of fiberglass to the inside and outside of the foam creating a super strong fiber glasses angled baffle to mount the speaker.

I mounted the MDF baffle to the door with some hot glue to hold it in place, some JB weld and finally I screwed the baffle in place - secured it to the metal doors skin. After the baffle was secured I tried a trick I saw on all the car audio forums using NON HARDENING Modeling clay to reduce vibration and fill any voids caused by the shape of the hole and the door.

The plastic door panel was trimmed a lil to get it to fit over the 8" driver, and a new piece will have to be constructed to flush the speaker to the panel. I have not figured this out yet, but Im sure it will require a lil more fiberglass and the stock speaker cover!

Once I get the system playing again, I will let you all know what I think of the new baffle. So far it looks way better than the last set up I made and the speaker is bigger so it should sound great! If you have any pics or suggestions how to make the cover piece I would appreciate seeing them!

I will post some pics of the rear deck soon!

This is my first build, but I decided to make some kicks for the sealed 4" speaker, and the 1.1" soft tweeter. The did not need sealed since the 4" was a sealed speaker. It was pretty easy with just some 1/2" MDF and some bondo glass. I covered them in a matching vinyl I think they look pretty cool for the first time!

The read deck is my favorite part... I was thinking the thing wold rattle like crazy and I would hate it. I was wrong. Its as solid as could be, and it sounds perfect to me. I am not a huge bass head, and I wanted less trunk rattle, I wanted better SQ and I wanted something that looked different than all the other SRT8 300C I have seen. I think this did it. The speakers are 10" Image Dynamics IDQ - When I originally got these I didnt think I would have a lot of power to run them, and I wanted to be sure they would fit under the glass in the deck. Who knows maybe I could upgrade some day to the MAX.

I used 3/4 MDF, 2 cans of spray foam, 3 layers of dynamat and 6 long bolts with washers on both ends.

I am happy with the results again I never tried anything like this before. I made the baffle and Chad From Xtreme Audio in Apache Junction AZ made the trim piece for me. He did a great job, I love the look.

**** *** car bro, great work on everything

07-11-2008, 10:00 AM
That is one **** looking car. I think I like the SRT-10 wheels a bit better but either one looks killer. With the stuff your installing it should sound just as sweet too, specially with all the deadening. The lower kick panels blend in to the rest really nicely.

Keep up the good work and post some more pics. I'm guessing the amps are going in the trunk somewhere.

Sweet build man. I wish I could throw some 8" mids in my doors. My 6 1/2's sound great but I could only imagine what 8's would sound like.

07-11-2008, 12:39 PM
one of the best 300s ive seen in a while

07-11-2008, 12:49 PM
you're inspiring me

07-11-2008, 01:08 PM
Wow thank you guys for all the compliments. The trunk is not done, I chose a carpet I did not like, and the installer didnt do the best job trimming it out. I decided to go with a different carpet, and I was working on the doors for way too long.

Hope to get the trunk DONE soon.

Here are some pics of what I have so far in the trunk (just the amp, ZAPCO DC650.6)

Build is coming together well. Nice work so far.

I absolutely LOVE the way your car sits on those SRT-10 wheels. That's the look I would be after.

Keep the pics coming. Love the speaker install thus far.

07-11-2008, 03:13 PM
Install looks good. I'm digging those kick panels..you should have did a couple of pairs lol My 300 might enjoy them as much as yours lol

07-11-2008, 03:25 PM
They were easy!

just do it!

07-11-2008, 03:32 PM
**** *** ride bro!

07-11-2008, 07:13 PM
**** those kicks looks OEM,

07-11-2008, 07:17 PM
I was just looking at the kicks, wish I would have mounted the speaker from the rear on there... But I didnt have the depth its REALLY close back there.

Thank you all for the comments I appreciate it... Wish I had better tools and the imagination of some of you guys. I look at things on here all the time scratching my head going HUH?

07-11-2008, 08:20 PM

Clean. Simple. Dark. Nothing outlandish or too fancy. That's my kind of car.

That's exactly what I would do to mine if I had one.

I still need to make a trim for them! Something to make them presentable

07-12-2008, 02:10 AM
Here is the one I love...


07-12-2008, 02:11 AM
Awesome work.

07-12-2008, 02:29 AM
woow i really like how you have the subs back there! do the windows shake alot?

07-12-2008, 02:53 AM
Thank you!

No the subs dont shake anything. They are not getting gobs of power, plus they are only a low end 10" woofer. I doubt you would have issues unless you had tons of power!

07-12-2008, 09:38 AM
So does the the 10's match well with the 3-way setup you have going?

Looks bad arse though. One of my favorite installs on here. I remember the last thread you had dedicated to the subwoofer section. Is coming out awesome! I wish I could hear it and better yet...........drive that sum bish!

07-13-2008, 04:32 AM
Thank you!

I am happy with the sub output compared to the fronts.

AS it stands I cannot tell where the bass is coming from! (remember I have not listened to it since I added the 8s - last time I listened to it I had the 6.75"). I am telling you the bass that the 160s had were awesome. I assume these will be even louder and deeper.

I am not a fan of huge amounts of bass, I would rather have gobs of midbass, and some bass to get all the drums pounding with good quality sound.

I think infinite baffle is the way to go if you want the sub closer to you in the cabin and you want nice good tight bass and you dont want to vibrate windows.

For me this is the best set up.

I was almost thinking of adding 2 15s in a infinite baffle facing the back of the back seat, using the trunk as the enclosure and keeping the 10s too. I was wanting to have a switch that I could throw to swap the amp power from the 15s to the 10s with a flip!

07-13-2008, 09:10 AM
I don't think you need the 15's if your not a bass head........even going IB with them. Then again I can't hear it from here, lol!

I just love the install and look overall of your car. Would love to rock something just like it, but yeah, that will never happen.

Have fun with it and take care of it.

07-14-2008, 12:51 AM
Well they are in, and playing. The bass is incredible, sounds like its coming from up front which is awesome! The baffle I built will not budge. No vibration, no rattle, nothing but tight bass.

I really need to get someone to tune my amp I've been me messing around really. I know nothing about Q settings, what frequencies to boost, and how to get them sounding the best.

I will take it to the Dynaudio dealer to play with the laptop program the amp comes with. You plug in your lap top to it, and there is a 11 band EQ with adjustable Q, and frequencies. Its pretty easy to play with, but when you dont know what you are doing makes it tough.

AS far as a trim piece, I might have to have someone do it, looks like alot of work to get the look I want, and I dont have all the router skills to get it done.

07-14-2008, 12:57 AM

that is very nice, I mean very nice.

Sorry if you stated, Just like reading a mag, I only looked at the pics. But did you vinyl the kicks or bondo and spray?

07-14-2008, 12:58 AM
Bondo, MDF, Vinyl
