I agree that the non matching subs are a bad idea, however the non matching subs are not gonna melt and catch his Bronco on fire like the wire will because it is too small. By build a box to spec I meant to leave the odd 12 out. I thought that would be obvious. Look at the shot of his build that shows the power wire on the left hand side of the engine bay. The wire is not even into the fuse block all the way. It has serious fire hazard written all over it. I believe in giving advice on sounding good when I can, but giving advice on keeping someones car from burning down should come first.
