Why does the red light come on when i hook the power wire up to my car amp?

take speaker wires off amp if the lit is green then speaker are hooked up wrong or blown.

on some amps there is a duel light. red and green usually. red means it is in protect mode or you didn't hook up your remote wire. if in protect mode, it could mean a number of things. did you hook it up with speakers and everything?

probably something corssed in your speaker wiring. be sure that you did not exceed the ohmage capabilities of the amp, and that no speaker wires are crossed, or shorting out on the frame. if you have too many speakers hooked up, that can reduce the ohmage, and your not supposed to go below 2 ohms -per channel, or 4 ohms bridged mono.

when you say redlight is on it isnt very clear as the power light for the amp is red...right above the cooling fan are 2 indicator lights and if either of them is on your issue can normally be addressed by faulty wiring, you may have wired the speakers at at an ohm load the amp isnt made for which over time will blow the amp if not right away. Also if you dont have inline fuses and such setup i the system then something as simple *** a power surge could have blown the amp...again since the power indicator(red triangle in the center of the amp) is red it could always be that your head units RCA outputs are bad if you have any hooked up at all.

try hooking the amp up with 3 wires, the red power wire, the black ground wire, and the remote wire, do not hook up the speakers at this time

1st check all of your wiring, make sure the remote wire is hooked up, check to see it the RCA's are hooked up. I know this sounds stupid, but i've done it a thousand times, check to see if you hooked up the speakers. If you checked all of those and still nothing, double check your ground. Make sure where you have it grounded, you have all the paint sanded away and its a good grounding point. The red light on the top of the amp, its not a protection light is it??

My best guess is that it would be your ground wire or even the power into your amp. I would check all the connections going to and from your amp

I think the blue wire is a standby "on" to be hooked to separate or system switch. Without knowing how you have system wired, I can' offer much. A bit of caution; having a thousand watt amp hooked to 6x9 dooms their fate

ground wires(heavy black)is connected when the red light lit.so no need check the red hot wire which is connected to battery terminal maybe loose.or theres no power comming in.thre are 2 hotwire in that amp one is red which is the main and yellow or sometimes orange which is the remote on. now if you sure that the power terminals is properly connected,ur speakers is working and input wires are good and still no sound. your amp is probably gone...do not try experimenting the wires or hook up two amp by any means..u might destroy all ur amp. hope this help u....

First of all, you MUST HOOK UP YOUR GROUND WIRE FIRST. You may have damaged it if you hooked your power and trigger wire first and then the ground wire. Unhook EVERYTHING except the hot wire, ground wire and trigger wire. If you still can't get the unit to come on then it is time for a trip to the repair shop. Good luck.
