Amp Trouble

[bigfun101 10+ year member]

I just installed a 2 channel hifonics amp in my car to run my door speakers. Everything worked fine the first day but now when I trun up the volmue I lose sound to my driver side door speakers. when I switch the RCA around the problem switches to the other side. Just wondering if anyone know what the problem could be beside the amp itself... please help!! //content.invisioncic.com/y282845/emoticons/eek.gif.771b7a90cf45cabdc554ff1121c21c4a.gif

Why would you think the problem is the amp if the problem moves with the RCAs?

Obviously one of the RCA cables isn't sending a signal when you get to a certain volume. Check your head unit.

OK let me run this by you guys.... I unplugged the one of RCA from the Amp so I only have sound coming from my drive side door. I switched the RCA cables from the back of my head unit ( left into right and right into left) but the sound is still coming from the driver side. what could that mean?? //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

That means nothing. The amp is what determines where the sound comes from. If you have the right channel from your head unit hooked up to the left channel on your amp, the sound will come from the left.

What I would do is leave both RCAs properly plugged in to the head unit, and then try them both, one at a time, on both channels of the amp. If one RCA has the problem on both amplifier channels then switch the cables at the head unit and again try them both, one at a time, on each amplifer channel. If the same cable, hooked up to both channels on the head unit, and both channels of the amplifer, has the problem...then you have a bad cable. If not, then you have a problem with your head unit.
