Car Amp. I was messing around with my car stereo, checking the subs to see if they were both working correctly. And I accidently hit one of my RCA cables (end/ metal part) on another metal connection on the amp. Well now my amp dosen't work at all. I changed the fuse on the amp and to the battery and it gets power but no sound. Is there a fuse inside the amp? .. Please please help me. I'm going crazy.

check your subs by connecting them straight from the stereo. If they work then there is an issue with the signal comming from the stereo through the rca cables to your amp, check those. Try another amp if you can with those rca's or test the amp with a friends car, either way try to rule out everything until it points to the problem.

try reconnecting your rca's from the deck to the amp when finished wire one speaker positive to positive on left channel and negative to negative on right channel then connect the 1st subwoofer. if all power and sound is fine and working turn off power to amp and connect negative terminal of 1st sub to positive on 2nd sub and positive from first sub to negative on second crossing the wires runs the speakers in series another way to try is parralel the speakers wiring by connecting positive left channel output of amp to positive on 1st sub same with the negative then splice positive to positive on second sub and same with negative.

it is most likely a loose wire or your RCA jacks need to be replaced for proper signal processing check all of your wires for continuity.

hey been there before u need new rca wires form ur radio to the amp.

yes it could be your ground..check your negative from the amp is going to the car body and not the battery. also try a new set of rca leads from the stereo to the amp..also check that your stereo audio out voltage is the correct voltage for the amp inputs.

i have the same amp and have that same issue before. yes you are correct that if you take off the RCA cables on the input there will be no light. either you have plug the remote line on the 12v or a grounded sub. it should be 12v/remote/ground from the corner. good thing im just fixing my sub earlier. it is no problem if you have hooked the remote line on the 12v, it is the same supposed to be. to check if your amp is working, short the 12v/ and the remote line and play your stereo and see if your sub is working. by the way, what sub are you using? i just blew my sub and need a new one.

Could be bad outputs from the back of your head unit or also could be bad rca cables. Make sure the amp is on and powered.

What kind of car? What kind of system? More details will help me assist you better. If it is an aftermarket in-dash stereo, it sounds like the blue/white wire is not hooked up correctly. This powers up the car's amplifier and lets the sound through.

Try hooking an mp3 player or some other source into the amp (in place of your car stereo)while the car is running to test it. You may have damaged the output of the radio. If not report the results here.

has your amp been accidently swiched to stereo instead of mono,if so,swich it back.
