um sounds like there is no sound input, if you are running rcas ensure they are plugged in and the radio and headunit, and check for a cut in the cable, this is very unusual not to have any power output at all, triple check your headunit outputs, and your amplifier inputs, make sure you arent crossed anywhere. hope this helps
I would say the wiring, in particular the earthing for it, also check any "Compression" fixtures.and check ALL joints etc. To be sure give the actual Amp a gentle tap, and see if that brings on the fault.
There are only 3 reasons this could happen. First, faulty components in the amplifier.
Second, and far more likely, is that the impedance of the speaker load is lower than the amp is designed for. If you are connecting (for each channel) the speaker + to other speaker + terminals and then to the amp, as well as connecting the speaker - terminals to each other and then to the amp, assuming all speakers have the same impedance, your load impedance is speaker impedance divided by number of speakers. Make sure your amp can handle that load and change it if it can't or you will fry it.
Third is if you connect speaker + to amp + and then speaker and amp - terminals to the car chassis. This is shorting part of your amp and will destroy it. Neither the - or + terminals should contact the chassis.
What you need to do is first ground your amplifier securely then make sure all connections are fastened. don't remove the speaker connection and listen for sound. If there is no sound power down the unit, and send it to a repair shop because it sound like you may have damaged some components in the unit. But in order to come to this point you have to make sure you ground the unit properly and then make sure all of your connections are secure. Contact me once this is done and you are ready to do some tests.
Hi Jon, you need to hook the Remote wire up to the Radios Blue remote wire. The car battery power stays on all the time. The blue Remote wire watches to see when the radio turns on, and signal the amp to turn on as well.
