Hey, I'm getting a new system and would like to get just one amp to power everything. The speakers are the Kicker Resolution RS5 5.25" components (90w RMS max) and the sub is a Pioneer Premier TS-W1241 (500w RMS max). The receiver is the Kenwood KDC-MPV7019, which I think has 2.3 volt preouts. I'm new to car audio stuff, but a few friends have told me that a 4-channel amp would be the way to go for this setup. Also, from what I've researched, the most a 4-channel will be able to give is around 75w per channel; if I bridge 2 of them to this sub, will it give enough bass for me to feel? Also, I've read about 5-channel amps, which sound like they would be good for this setup. The Lightning Audio S5.700 seems like a good one. If anyone knows of a 4 or 5-channel amp that will give a good amount of power to all the stuff, or has another opinion on what to do, please let me know.
