Well I definatly agree that the deck needs a change esspecially since the usable preout volltage on that panasonic deck is like 1.1 volts. I think that the 275R is a great amp, although I am not sure if its gonna be sufficent power for the 4 subs, and if you up to the alluminums than I really doubt the amount of power you will have. Mabye look at the 2100 instead. Nice amps though. As far as going with 4 12's, what are you trying to achieve in the end as far as preformance goes?double-secret reverse-osmosis speaker-cone-induced high-level interference distortion, Its a killer

i have used MA Audio amps for a couple of years now, they have worked very well and seem to be prices pretty good.  subs is up to you, ive got Audiopipes now and they work great for me.  go with Titinium subs if you've gtot the money for them.
