hey fellas yes im a noob on this system stuff ok so take it easy on me lol.. well ive already spent alot on my system. it bumps pretty good now but im a bass freak, but now i want low clean bass that travels like a mofo. i have an 04 extended cab right and i currently have 2 12" kicker cvxs in a ported box just chillin on top of my seat(ghetto i kno) they are bein pushed by 2 alpine pdx 1000.1 so 2k watts to each speaker. my problem is i want more deaper bass and i also wanna put the box under my back seat so 10" woofers would be my solution. i kno its gunna have to be a custom box. i was thinkin bout 4 mtx 8500 cuz they would go perfect with my amps or 4 kicker cvx but once i read these forums i realized that they would sound chitt* cuz no air space. please help me out i guess im lookin for 2 10" now so they would have more air space to go under my seat. my budget is around 4-6 hundred for the pair, thanks fellas much appreciated
