well you can always use the factory amp, i'm not sure what the RMS output might be.. i went and upgraded to a 500 Watt RMS when i got my video/sub/rear 6x9's installed, and everything sounds great... i would say, if the HU provides the same output (i.e. 50w x 4), then you may not have to get a new amp, provided you use the same speakers, because the head unit acts as an amplifier in a way, but if you ever plan on upgrading them, a new amplifier is required .. good? __________________ [SIZE="1"]Current: Cooler, Intake, Headers, Valves, MAF, Exhaust, HIDS (white/blue), 17" ASA tuner with low-pros, tint, dvd/audio, I stand strong; Life's a slinky. |
