ok... being as I was having problems with my soundsystem and totally burned out my backspeakers and am now selling my old amp, the time has come to buy a whole freakin new one for the third time... wanna make sure I get this right finally 
 
Anyway, I'm gonna have four infinity kappa 63.7i speakers, an amp for them (not sure which one yet) suggestions on what would be a right amp would be great, and hoping to have two 12" subs (preferably infinity perfect). 
Specs on the speakers:
    »  3-way car speakers for 6-1/2" and 6-3/4" locations (pair) 
    »  2-ohm impedance 
    »  Plus One woven-glass-fiber woofer cone with rubber surround 
    »  EMIT tweeter and M.M.D. midrange 
    »  computer-optimized outboard crossovers with tweeter level control 
    »  power range: 2-75 watts RMS (225 watts peak power) 
    »  frequency response: 45-25,000 Hz 
    »  sensitivity: 95 dB 
Specs on the subs:
12" 4-ohm subwoofer 
aluminum cone with high-roll butyl-rubber surround 
massive cast-aluminum basket 
suitable for free-air use (handles up to 175 watts in free-air applications) 
power range: 75-350 watts RMS (1,400 watts peak power) 
frequency response: 18-200 Hz 
sensitivity: 96 dB 
top mount depth: 6-1/8" 
sealed box volume: 1.0 cu. ft. 
ported box volume: 1.75 cu. ft. 
Questions are: what are the right amps for the speakers and subs? Also, are there any other places to mount the subs rather than putting them in the t-top spot?? Being as my cars t-tops are never on in the summer, this is a question that's puzzling me. If there's no other mounting option, then I'm not sure that subs are even an option for me.
