PROBLEM
Amp or powered sub does
not turn off when you turn off
the vehicle
One channel on the amp isn’t
working
1. This situation happens when you connect the remote turn-on wire to a constant 12V power wire (often this
is a yellow wire) instead of to the remote turn-on wire of your receiver’s wire harness. Pull out your receiver
and plug the amplier’s remote turn-on wire into the proper remote turn-on terminal of your receiver’s wire
harness.
2. In a rare situation, the remote turn-on wire input is touching the power wire, which can also cause this
same issue. If this is what is happening, then simply take the remote turn-on wire out of the amplier terminal
and carefully put it back in so that it is not touching the power wire.
1. Check the RCA cable that is going from the amplier to the receiver. We recommend having a spare RCA
cable to test with. Many times RCA cables go bad since they are thin cables. You can also test your RCA
signal using a multimeter.
2. Check the RCA cable that is plugged into your receiver. Make sure you plugged the amplier into the pre-
amp output that is red and white. In many cases we have seen customers plug the RCA into the RCA video
of their receiver, which is yellow. If this is the case, just plug the RCA into the proper connections and your
problem will be solved.
3. There is a setting on your receiver that can disable your RCA outputs. The setting is under fader/balance
control. On your receiver navigate to fader/balance and nd the setting, then make sure you enable front,
rear, and sub preamp outputs. Sometimes the head unit will allow you only to enable front and rear, which
would cause the amp to have no sound.
4. Speaker wire is not making a good contact on the speaker output of the amp or on the speaker terminal.
You need to make sure the speaker wire is securely tightened into the speaker terminal and the amplier
terminal.
5. Make sure the positive speaker wire is connected to the positive terminal on the speaker and on the amp,
and make sure the negative is connected to the negative.
6. Make sure the gain of the amplier is turned up.
