I just thought I would share with everyone what I got and what I plan to have, just because I wanna know what you all think.

3 10" MTX Thunder6000's Subs
350 Watt RMS Kenwood Amp (OLD)

System To Be:

JVC KD-SH77 Head Unit - It's Still Good
2 Sets of 6 1/2" Infinity Kappa Perfect Component Systems
2 12" Infinity Kappa Perfect Subs
MTX Amp to Power Components (Not sure how big)
400 x 2 Watts RMS MTX Amp For Subs
2 Monster Cable 1 Farad Digicaps

Explanation on how the Hell I can afford dis Shiznit:

My brother works at a Circuit City. And Circuit City employees can get there sh*t cheap. Like the Infinity Kappa Perfect Components, the go for like $500 in Crutchfield, my price: $185.50 :D . Do you guys thing this will be loud enough or should I think about getting one more Sub? My bro says that'll be a bitch to hook up to an amp tho because 3 subs into 2 Ohms is difficult, not sure why, but he's the audio expert, not me. Well, thats my dream, hopefully it will be realized in a couple months, right after my kit and paint job are done. :frog:

I'm assuming this will be your daily driver, in which case 2 perfects with 400 watts apiece is more than enough. The system how you have it planned now will more than likely get loud enough that youll have to turn it down after awhile of having it loud cause it hurts. I was just wondering, are you getting the DVC or SVC perfects? Cause if your getting the DVC's(not sure if they make the SVC anymore) I was just curious as to how you were gonna hook em up to the MTX amp, seeing as from what ive heard MTX amps are not 1 ohm stable.

Actually I believe the Perfect I'm getting is SVC, even though it's they're newest and most expensive one, but I'm not positive. As I said, I know little about audio tech, that's all my bro, so he'll set me up right. :frog:
