This is the amp setup you need. 4 channel on the left for the Front/Rear speakers and a bridgeable 2 channel on the right for the Sub(s). You could also substitute a Mono amp for the 2 channel shown for the sub.
And what brand/model amp would that be? Don't cheap out for the amp or speakers.
i was gonna go witht his boss amp: BOSS AUDIO PV3700 Phantom 3700-Watt Full Range, Class A/B 2-8 Ohm Stable 5 Channel Amplifier with Remote Subwoofer Level Control
