PROBLEM
Amp won’t power on
Power but no sound
1. The external fuse is not properly secured to the power wire or is not making proper contact to the wire.
Ensure the fuse is properly seated and making contact.
2. Your external fuse (inside the fuse holder) is blown. Replace the fuse. Never replace the supplied external
fuse with one of a larger value.
3. Check the ground wire. Make sure the connection is 100% secure and tight.
4. Power wire is not connected properly to the ring terminal or it has acid corrosion on it. Check the connec-
tion to the ring terminal and use a wire brush to clean any corrosion off the ring.
5. Check the power wire. Make sure the positive is wired to the positive, and the negative is going to the
negative. Make sure the power wire is secure.
6. Check the remote turn-on wire. Make sure that this wire is connected securely to the amplier on one end,
and make sure the other end is connected to the remote turn-on of the receiver. A common error we see is
the remote turn-on gets connected to the antenna wire instead of the remote turn-on wire of the head unit.
Please note the remote turn-on wire is a required wire. The amp will not work if this is not connected.
It is also possible the remote terminal is loose and fell out.
7. Power wire is connected to the ground terminal of the amplier. Connect the power wire to the +12V
terminal of the amp.
8. Power or ground wire became loose. Check all connections and make sure they are tight.
1. Check if any protection lights are on. If protection lights are on, please refer to the “Power and Protection
Circuitry” section on page 12 and the “Amp goes into protect mode” section on page 18.
2. Make sure the RCA cable that is plugged into your amplier is plugged into the RCA input. If you have it
plugged into the RCA output, then the amplier will not get any sound.
3. 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
