Pretty much same kinda design. I know my subs are 12" and I will need to expand the boxes for a little more depth I believe. To get the required •sealed box volume: 0.5-1.0 cubic feet •ported box volume: 0.8-1.6 cubic feet.

I Need / Want my floor space Open, and this type of install will allow that, plus let me use 2 subwoofers.
I just bought and recieved a second Pioneer GM-D8500M mono amp, and will be ordering up a second Pioneer TS-W3002D4 subwoofer and the matching Grill.

These were just done, and posted on a HHR Forum I am on and it's a perfect solution for me and to be able to have a pair of subs without sacrificing floor space or my spare tire, jack and other things I would like to carry in the well area.

As I said, I do have 12 years of body and fender, and auto painter experience, I have a complete woodworking shop in my garage, 6HP 80 Gallon air compressor, sandblasting cabinet, fully tooled to do just about anything, garage is Heated and is AC'ed as well.

I just never made a subwoofer enclosure before. Not saying it won't be hard to do, just that I can't afford to spend that kinda cash having them custon made.


I gutted the interior and sound deadend 90% of the interior roof to floor, doors are done with a layer on the inside outer door skin and then the door is sealed up and a layer on it directly behind the interior door panels, roof and floor are 100% covered, rear spare tire area is 100% covered as are the rear quarter panels.I did not tear the dash out to get in behind it and the firewall, to much work to do that. Huge improvement in the car overall. In the area were the door speakers are I did add a 12"X12" area with 3 layers (4 total overall) directly behind each of the speakers.

This pic shows the area with the interior panels in place, the rear floor is in the upper positon to help keep the current subwoofer from sliding all over the place in back. The Flat area, were the glass would have been, is a seperate piece and can be removed, without having to cut up the interor panel.

Ideas and thoughts on how to do this is what I am looking for, not sure how to achieve the outer rim area that fits around the outside edges.

Not sure how much materials I will need, 2 gallons of resin, sheet of 3/4" MDF, and how much and what kinds of fiberglass should I get?

Thanks
