I've running the four speakers (3 ways) on one amp @ 125 watts each channel),the two subs ( 135 watts each ) on the other amp & got two channels free right now.
I bought the amps used in excelent conds,they are sony Xplode 550 watts each;didn't use the factory wiring,i runned the long way by adding new wiring all around the VX for all components,at 60% of power the VX shakes like a gelyou can clearly hear the music from out side.
Even though i love music pumping down the street i fall into the moderate group category.
