thank you for all of the advice. right now i'm tight on money so iv been thinking i'm going to get a xs d3400 and try to put it under the hood and if that is not enought put a second one in the back. i have one xtx5000.1 for 2 ssa icons and i'm thinking about getting another amp. hopefully 2 3400s would be enough for roughly 4000 rms at 2 ohm? (sorry if i steal your thread)
