i put a 4 channel 1000 watt amp in my car for the door speakers run it like any amp to speakers just make sure the amp is on full or high pass and the level is low, my amp really only puts out like 75 watts x4. usually RMS is 1/2 the max power or at least do that to be safe. your high notes will be so loud i suggest geting a component system they are very easy to hook up even if you do not have an amp only 2 wires into it and 4 out which go to a mid peaker and a tweeter the combo willsound very cear
