Everything that you are looking at is basically total crap - not trying to piss in your wheaties, but all of those amps will in no way shape or form put out their advertised power unless hit by lightning!!

Buy another Alpine, buy a JBL 600.1 amp, then find someone who can build you a good ported box and you will be well on your way to being deaf

That sub will work fine, just add a second one. I don't even think some of those boxes you were looking at would fit in your car, and guarenteed that all will sound less then pretty.

I know it sounds like you want just SPL, but you shouldn't use your hard earned money to buy less then decent gear just for the instant gratification of it. That's just my $0.02...
