[QUOTE="chris229, post: 58149, member: 542614"] so no matter which amp you plug JUST one set into it sound fine BUT when both sets are running it degrades the sound--------UNLESS you activate a crossover on ONE of the amps-------ummm well ---a HU can run out of signal when split BUT this isn't common. Is the spliter directly on the HU or on the end of a extended RCA cable? if it's on a cable---change try switching the main cable-------i don't know why the x-over would fix the problem. Maybe the HU just can't drive a split RCA---but something is a miss here cause the X-over fixes it. YOU 'd need to put the outputs on a volt meter or scope to see what is happening. Run a test CD and measure the signal voltage at the amp with just one amp wired THEN connect 2 amps and see if the voltage drops [/QUOTE]
