Possible RCA problem?

[UNIT 6639 0]

Hey guys, I am having an issue with my amp I am wondering if my RCA's are bad, I had them loose in the trunk while my amp was uninstalled, could they have touched and burnt out or something, I didnt tape them off, only the power wire and ground, I didnt think they needed to be taped off as well.

But my amp is sounding unright! the output is very low, I turned the gain up to max and it does not sound like a 1200 watt amp should sound, I dont know if that makes sense.

I say that because I switched amps, from a eD 9.1 to a RE 12.1, nothing changed except the amp, all wiring is the same, the 9.1 was thumping, I know both amps are different but they are both supposed to put out 1200 rms so I am hoping its the RCA's.

I am going to pull the HU when I get home and make sure both RCA's are in the HU, i may need to buy new ones to rule that out, is there a way to test them without special tools?

If you have a DMM set it to AC volts and measure the voltage between the pin and the barrel. Use a test tone for a consistent reading. If you are getting voltage there, the problem is with the amp, not the RCAs. It probably wouldn't be an issue withe RCAs themselves but with the outputs of the HU. If you are not getting voltage, the HU is the next thing I would check.

dmm is proll the best way to do it, if u have a buddy that has a system barrow his amp n sub proll the only other alternative... it could also be you box maybe? or the amp itself hope u get it fixed
