Default My audio project has begun

After several weeks of driving around with the very crappy Subaru "premium" sound system, I finally tore the car apart and decided what to do with it. I started with around 50 sq feet of sound deadening pads throughout all 4 doors and under the back seat. Then, I went ahead and started sealing off the cabin from the trunk. Several layers of SDP's and numerous trips back and forth to cut the baffle down to fit, and I finally have the sub mounted. I went with a single 15" driver, firing through the ski hole in the seat, using the trunk as the enclosure. This configuration allowed me to get extremely musical bass and frequency response flat out below 20Hz while only adding around 50lbs for the actual hardware and still maintaining full useable trunk space.

Next, I'll install the new Pioneer Premier P940 in the dash and a 400W amplifier inder the passenger seat for the sub. For now, I'll use the head unit's amplifier for the front speakers. I found that the factory tweeters in the front don't sound too bad once you bypass the stock crossover capacitor with a high quality 1uF film cap. It really increases the volume, as well as extending the frequency response, both high and low (it lowers the crossover point of the tweeter when you do this). This, combined with generous sound deadening pad application in the front doors, makes the front speakers sound much better. Of course, I'll definitely replace them soon as well. LOL

nice. Could you post some more pictures of your sub box? Like from behind?

This is my current sub but I'm looking for something else:

I custom made that box to fit behind the seat of a pickup truck i used to have, and it happend to be the perfect size to fit under the frame crossmember in the WRX's trunk. It actually fits so tight that it takes a few minutes to get it in or out. And it takes up almost no space in the trunk.

It's only 0.65 cubic feet which is enough for the JL 10W6 but I'm not sure if the JL 10W6 is enough for me! Thats why you see a Boston 15" in this picture.

Looks really cool, but how much weight are you adding to your ride? I was thinking of putting in a system, but I'm more performance on the road oriented.

I am definitely sensitive to the weight I'm adding, so the total added weight of the sound deadening pads and the sub/baffle/amp total weight will be under 100lbs.

Here's a pic of the tweeter mod. I also realigned it to match the factory grill. It was actually pretty far off. I gave it a slight upward tilt, as well.

First, what kind of sub is that? Where can I find info?

Second, do you like it free air? Have you considered AP mat? If so, any reason for not using it? Thanks.

The sub is an Orion prototype of the original NT subs. I got a few sets when I worked at a shop back in 95.

I haven't actually powered it up yet. I'm waiting on the head unit to arrive in the mail. I prefer infinite baffle configurations, due to the lack of box coloration and resonance. The low frequency capabilities of IB are incredible when implemented correctly. Plus, the total added weight and loss of space are far less! You just need to make the rear deck more rigid and use lots of sound deadening in the trunk to keep flexing and rattles to a minimum.

I finally got the head unit installed. It's a Pioneer Premier DEH-P940MP. It's neat. The remote is pretty lame, though. No way would I mount it to the steering wheel. LOL

did you fiberglass the mounting surface? i'm wondering if i can fit something like this in my trunk because i have a cusco strut tower bar with v-brace, not much depth or anything unless i maybe mount the sub high so it comes back in the middle of the braces, but then i'd have to remove the braces to fit the enclosure in, and then i dont know if i could put the braces back on! anyone run into something similar? aiming to get either around 1cu ft for a sealed box, or 0.8cu ft for a ported box, but not sure if there's enough room for that much.

The sub is mounted to a 3/4" MDF board, which is mounted directly to the back of the sheet metal lip behind the seat. There is no enclosure behind the woofer, so it takes up very little space.

Default i have the same setup

i use kicker c10 inifinte baffle sub through the passthrough. check it out...
i would think a 15" sub would not have enough room to move, hitting on the seats.

I mounted my woofer from the back of the baffle, so there are no issues with the surround making contact with the seat.

that's a good idea to mount it behind. i think i'm going to put a 10" ported box in the pass through, not sure how i'm gonna mount the sub. Probably just use 1/2" mdf for the face, cut the entire diameter of the sub, then make another piece of 1/2" mdf cut with the mounting diameter, screw those together with some liquid nails and i can flush mount the sub. I'll probably make some sort of grill to protect it too, anyone know any good plexiglass shops? i might ask gately audio, but does anyone know any other place?
