I have my receiver and front and rear speakers picked out. The recevier can go 57.5 peak per 4 and 27 RMS the max is 230 watt it says on it. The RMS of my rear speakers are 2-80, and the peak is 400 watts. My fronts are 2-50 and a peak of 220 watts. My question is, can you wire a amp from the receiver to just the speakers without a sub? Also what wiring would I want to install to get the best sound, instead of factory for the speakers.
