Hmm...that would truly take some custom work since the bottom of the deck is far from flat...I MAY be able to pull off an amp that isn't very wide. Is it safe to mount an amp upside down?

Most of my listening is classic rock and rock..but there's also rap and techno type stuff...if the sub falls on its face when the bass 'drops' I swear to god I'll pull over, rip the sub out, and pitch it into traffic. Alpine Type S sounds like its right in the power handling range I want, and Dual Voice coil = cleaner sound and a mono block amp that I need to bridge down, right? MTX also makes the MTX 4510-44 (as well as a million other 10 inch subs) for about half the price that works about right and also has a dual voice coil. I've heard Alpine's new stuff is garbage, but I have no idea if MTX is worth shit.
