First what are your opinions on the following brands in the mentioned area: -Audiobahn (subs/amps) -Alpine (headunits) -JL (subs/amps) -Boston Acouostics (speakers) Now here is what im going for: I have a 95 blazer 4 door, it has 6 1/2's in each door and a pair of 4x6's in the dash. I want to run a set of components in the from and a set of 2-way coaxles in the rear and possibley eliminate the 4x6's... not sure though. For subs and amps I want to 12's in a sealed box and I would like to keep the number of amps to 2 if possible a Mono Class D and 4-channel. My problem comes in on power to the subs, I want to run at 4 Ohms just so I dont put to much of a stress on my amp, what amps out there produce a good 700-1000 watts at preferably 4 ohms??? I know Ill come across a few other things but thats what Ive got for now.
