The system includes...

Sub - Digital Designs 9515d
Components - (4) Boston Acoustics Pro 60 Components
Head Unit - Pioneer DEH-P980bt
Comp Amp - Kicker SX700.4
Sub Amp - Kicker KX1500.1

I did all the work myself, just looking for something clean and neat, and wanted to get the most sound out of my limited space. I had several installs under my belt before this one, but this was my first attempt at sound deadening and fiberglass. I started by taking out all the interior and sound deadening every square inch. I used peel-n-seal roofing material for sound deadening, and I think it has worked well. It stuck to everything well, only smelled for the first few days, and didn't come loose during the hot days of summer. I used 200sqft, about 3 layers total.

I used four boston pro 60 6.5in components, run off of a Kicker SX700.4 amp.

I coverd this whole with blue paiters tape and made a mold with fiberglass. I put the back interior pieces in when I made the mold that way the box would match up with the interior.

Once I had the mold made I covered it in several more layers to give it strenght and then cut a piece of wood to mount the speaker in. The wood was to help give it strenght and give me something to mount my ports to and run my fiberglass onto to make it look good in the end.

I sanded down the fiberglass until it was somewhat smooth and then gave it a test fit. You can see that it ended up not quite matching up with interior, but it wasn't too bad and I was able to get it evened when I put the body filler over the fiberglass. I sanded the filler smooth and then took some thick exterior paint and a roller that would give a texture similar to that of my interior and rolled it on. Then I mixed up some automotive paint I had left over from previous paint jobs and got a color that matched the interior pretty close and painted it. I took the pictures of the finished product before I got the interior panels all cleaned up, they still have dust all over them.

I welded an amp rack where the spare tire used to be, and mounted a Kicker KX1500.1 for the sub and Kicker SX700.4 for the components.

Like I said I did all the work myself and bought most of this stuff used. Total cost was:
Sub - $260
Pro 60 - $300 for all four
SX700.4 - $150
KX1500.1 - $200
Pioneer 980bt - $300
Fiberglass - $140
Body filler - $17
1/0 power wire - $30
Peel-n-seal - $200
TOTAL=$1580

All the other wires and fuses I had laying around. Not too bad, huh? I have lost a lot of pictures of this install on my hard drive, but will post if I ever find them. Here is the only pic I can find of the car itself.

x2, im sure that DD is having a asthma attack at full volume, lol.

But, overall nice work, im all for cost efficient builds :D

very clean box :)

The ports are 2in diameter, wanted one on each side to make it symetric.

The box is 4.3cuft. Tuned to 38hz. I don't think it would be possible to get any more volume out of that space.

I would have gone with at LEAST two 4" ports personally.

Good work though.

is that before displacement ?? wow you fit more back there than i was told i ever could you have given me hope was it hard to work there ?? i looking to fit 4 before displacement tuned to 36htz

how does it sound?

12-07-2009, 08:39 PM
ok your ports are way too small

Varinabassing
12-07-2009, 08:42 PM
also i was wondering about the t top rack studs did you mold around them or cut them out ??

12-07-2009, 08:44 PM
looks cool but fail on the small *** ports man! all that work for what? it doesnt even look like there is nearly enough port length u have there! looks like 5" per!

does it even hit below 45hz???? :confused:

all im saying is great job on the box bad on the port diameter choice...

4.3 before displacement. It was a pain to get it all taped off and get the first layer of fiberglass down, that's why I quit after one layer and let it dry, took it out and then added more layers for strength. If I were to do it again I would tough it out and do all the layers at once in the car. The way I did it caused it to warp a little from the heat of all the added layers on the thin mold.


I molded around the studs.

Ports are 3in, not 2. Thought they were 2 but just measured. I really didn't know it would make that big of a difference if I went with a smaller diameter. I'm not that experienced with that sort of thing. As for how it sounds, I don't have any complaints. Hits the lows well, sounds deep. If it would really be worth while I could change to bigger ports without too much trouble.

should of done some research...you do realize that the length of the port effects how the sub sounds to you?

was just thinking that.. OP therefore has no idea what its even tuned at .. :confused::confused:

nice install work, but yes you should have researched more. Not the ideal enclosure for that sub...

there not even aeros...

i mean, the rest is beautiful man, should of just went with a sealed enclosure instead of suffocating that poor dd

I can't really say that I knew exactly what I was doing on the ports. I really did cheap out on not using aeros, I know, but was trying to get by without much money. I talked to the guys at DD about ported vs sealed given my volume, and they suggested ported and gave me the specs for the ports if I were to use 3in diameter.

What would I gain by using larger ports?

you have to be able to hear the air getting "forced" out of those ports. Like a chuffing sound...

I was worried I would have some noise, since I kinda rigged them up instead of using aeros, but I didn't consider having them too small would do it, well, having them 3in anyway. I don't hear it if they do, but I could be wrong. I will take a good listen and let you know.

You'll be O.K. as long as this is your daily and not for comp.

transamfan
12-07-2009, 10:03 PM
No, not for comp. Never meant for it to be for comp. Just wanted to try and give myself a system and install that was a few steps up from the basic wooden speaker box covered in carpet.

Nicely done!! I bet it sounds great. I bet those Boston pro's just scream. I wouldn't trip out on all of the comments about your're ports. You done good. As for me, I had my box built by a pro that really knows what he is doing.

The DD on the speaker is a sticker, not paint, and you can get them from DD, just have to ask for them.

Yep I did the all silver dd logo on my 4 9515's....looks alot better than the red and silver.

I dunno how it sounds, but that custom enclosure molded to fit the back look pretty nice...

Way cooler than the old drop in premade CTFs (Camaro/Transam/Firebird), if you guys remember them... I think Kicker was the one that cam out with those for like 2 10" Comps and maybe a set of Mids/Tweets....

Looks nice man...

I had one of those prefab things in my 88 GTA and was very disappointed in it. I love the one he built, as it looks like it was meant to be there

been waiting for a Trans am build log forever!!!

I want a box just like that!!!


bump for a fellow LS1!!

car specs :)???

That's the main reason I posted this, because when I was looking I couldn't find anything cool to base my build off of, and couldn't find anyone putting more than just a couple of 10s in a crappy box in one these cars. I really don't think you could get much louder in a trans am without going pretty radical and using the back seat, just not enough volume for a box.

All I have done to the car is the system and lowered it 2in, put on some American Racing Torq-Thrust 2 wheels. Got to take it a little at a time.

haha yeah, I bought a sealed box that was made for the hatch area, because I don't have the supplies to build one myself..

Im thinking about stepping down from 2 12"s on 2krms, to 1 10" on like 1krms

I got out of the audio game and started spending on performance mods ha.
