interesting read fellas, i guess its also dependant on what kinda box / car/ music/comp we are doing, and what kinda sound we like?(punchy / smooth) either way i think ill stick to less powerfull amps for a while, running fat wire and ho alts and extra batteries strikes me as no fun, especially as it gets plenty loud in my car off a class d 600 wrms and 1 x12", stock everything and 4 guage. but if i ever want 2500+ wrms in my ride (and i would love it, just for the "make your passengers chit" factor:up2somet: ) i know where to come and who to ask.
