Amp is on but no power output

disconnect the speaker wires from the amp, and check for power. there is no resetting, other than simply turning the amp off and back on. if it powers up fine without the speaker/sub(s) connected, check your wiring and check the ohms with a meter. if you do not find a problem there(should read within 1ohm of how you wired it) then check for dc voltage coming out of the speaker terminals on the amp. should also check that the amp is getting good power and ground. if wiring and speaker(s) check out okay, then the amp is damaged. if you get dc voltage from the speaker terminals, the output transistors are shorted out and it needs to be repaired by a tech.

Amp is probably going into protection mode, or does not have enough current from the power wire to continue operating. Check that the speaker wires are not shorting out against each other. Also check your power wire and ground wire. Ensure that the amp is solidly grounded. Are you using the proper gauge of power and ground wire? (4awg recommended.)

The best places to look are:

1. Remote wire running from fuse box or back of head unit.
2. Ground wire, make sure it is connected good the the body of your vehicle. (I almost threw away and $700 amp because the ground wasn't secure enough).
3. If equipped, inline fuses on power wire or connections on battery.

If all these check out, then its probably a short inside the amp. You can have them fixed, but sometimes it cost just as much for a new one! Hope this helps and good luck!

Make sure you don't have any shorts on your speaker wires or rca cables. Unplug one at a time, the turn on power until it stays green with no protect light, then you know what input is causing the short. If you remove all speaker wires and rca wires and all you have connected is the ground, power(12volts) and remote and it still lights up red/green(in protect mode) then your problem is the amp.

There should be an amp input level control somewhere close to the rca inputs...does this have any effect?

Here is the breakdown of what wire does what:
+Red..............12v ignition
+Yellow...........12v battery
-Black............Ground
+Blue.............Power antenna
+Blue/white.......Remote turn on
Orange...........Dashlight/dimmer
Orange/white.....Dashlight/dimmer
Orange/black.....Dashlight/dimmer
+White............Front left positive
-White/black......Front left negative
+Grey.............Front right positive
-Grey/black.......Front right negative
+Green............Rear left positive
-Green/black......Rear left negative
+Purple...........Rear right positive
-Purple/black.....Rear right negative

Hello mcis43fan,

The protection circuit can be activated by shorted or grounded wiring or it can be caused by a defect in the amp itself.

First, disconnect all wires except power, ground and the remote turn-on lead and see if the amp powers up normally. If it still goes into protection, the amp is defective, most likely shorted outputs and needs repair or replacement. If the amp powers up normally, test the other wiring for shorts and grounds. You can reconnect them one at a time to determine which one is causing the problem.

Hope this helps.

have u connectted the remote wire from head unit to turn amp on? have u got + and - the rite way round.hope this of use.

check pwm chip ,may need replacing

Disconnect all input and output cables and check. If the light stays red, it suggests an internal error. If not, proceed by first connecting the Sub wires and checking, then the input RCA's and checking. Remember to switch off the system before connecting/disconnecting, I suggest also removing fuses during this process.
