[DeTomaso] Subwoofer question

[JDeRyke at aol.com]

I see nothing wrong with the idea; at one time, I considered adding a 
beer-case-sized box in that area with a key-lock door for an extra amount of 
baggage-carrying, but I've got too much stuff in that area now on the engine side. One 
Nor-CAl owner did much the same thing as you're suggesting, creating a 
shallow box that held the adjustment dials for his ignition amplifier and the ECU 
for fuel injection. The box was centered behind the passenger seat & was flush 
with the upholstering. If you want the addition more directly facing the cabin 
so sound doesn't bounce as much, note that in the lower rear corners of the 
cabin, there's a welded attachment for the big hoop structure  that braces the 
roof, so when you cut the firewall, I'd suggest starting about 2" away from the 
floor and right side (with seat & all upholstery removed), and nibble your 
way to the edges but do not mess with the roof brace. Stainless brazes 
beautifully, so if done neatly, the structural integrity of the chassis should be 
unaffected. The structure should also remain waterproof and fireproof, too. Good 
luck- J DeRyke
