rear deck panel replacing 6 with 6 x 9

Hi, all

My car is a Toyota Corolla '99 Sedan (the rear deck is similar to a camry), and I was wondering how I would go about replacing the factory 6" with Pioneer 6 x 9's. The parts of the rear deck is the car body metal sheet, and over that is a wooden panel(which has been torn...dont ask =P). So im thinking of replacing the wooden panel aswell.

1. What should I replace the wooden panel with? Plywood? Its quite thin, about 7mm..

2. Do you install the 6 x 9's into the wood, or into the metal sheet under it?

3. I want the maximum bass to come out of these speakers, so what should I look out for? Should I use some dynamat under the wooden panel? Fiberglass the 6 x 9's ontop of the panel?


Thanks in advance.

Are there torsion bars beneath the rear deck for the trunk lid?

I would not under take this drastic of project just to down grade to 6x9"s. Stick with quality 6.5"s and keep it simple.

There is fiber board at most hardware stores that is thinner and more flexible than ply wood. Carefully remove the stock piece and use at a template for the new one. Cut the holes for the speakers to match the rear deck, then lastly carpet it, and for crying out loud get some plain black speaker grills, not some gaudy, flashy ones that are usually supplied.
