mini_mull said:Why not just bedliner your current dash? I've seen it done and it looks good. I could dig up a pic if you're interested. Also, for the best sound stay away from metal boxes. Fiberglass or MDF sealed with bedliner would be a better option. If you had to do metal you'd need to sound deaden the whole thing for decent sound.
Well, on the dash, I'd like something that isn't going to warp easily, plus if water got up underneath it, it'd rot out pretty easily. It's possible that I could just take a new dash pad, and coat the underside liberally with some poly or something to seal it really well...almost turning it into a fiberglass-like material.
I know metal isn't the best material for speaker boxes, but mainly because it has resonate properties. I'd take steps to kill the resonance, namely, I'll probably paint the whole piece in Lizard Skin, apply Dynamat to the inside, bedliner the outside, and then make sure the area behind the speaker was properly stuffed with poly-fill.
