Thanks for the info. Any idea what color the remote wire is? And, any idea what colors are used for the speaker wires? I have to tap into them, for an amp signal (as I assume the stock deck does not have any RCA outputs).

BTW, I figure I won't have to bolt down the masonite sheet, as the mass of the subwoofer and the perfect fit of the panel ought to keep it from going anywhere. And, I figure a 1/4" thick masonite panel with holes drilled through it will not add more than a few pounds. to the car, esp. if the stock cover is removed and stored away.
