check your speakers and speaker wires for shorts and/or grounds.

Hello billyelder,

If the amp is powering up but not producting any sound, there are 4 possible causes.

1) Incorrect or faulty wiring.
2) No input or input too low for the amp.
3) Defective speakers.
4) Incorrect amp or head unit settings.

Start by checking all of the wiring and onboard fuses. Especially check the speaker wiring and make sure there are no shorts or grounds and that the insulation is not nicked or frayed. Check the RCA cables by substituting a known good pair. Check the receiver (head unit) to see if there are any settings that need to be turned on for the preamp outputs to work.

Test the speakers on another output to determine that they are functional.

Check the amp settings and insure that filters, crossovers and gain controls are properly set. If your wiring and the settings all check out and the speakers work on another output, the amp itself is probably defective.

Hope this helps.

If the amp is in protect mode, it probably has shorted output transistors. To eliminate other possible problems, do the following. Disconnect all speaker wires from the 'amplifier's speaker terminals' and disconnect RCA/signal cables from the amp. If it powers up normally, the speakers/wiring need to be checked. If it still shuts down (goes into protect mode), the amp almost certainly has shorted output transistors and will need to be repaired. If the amp only shuts down when it's driven to relatively high volume, you need to confirm that you have sufficient power supply voltage. With your multimeter set to DC volts, the black meter probe on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle) and the head unit on (so the amp will have remote voltage applied), touch the red probe alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low. If both the B+ and remote turn-on lines are low and your battery is fully charged, you may have a bad ground connection.

Hello bloodyspokes, For the amp to go immediately into protection, something is probably shorted, grounding out, or not grounding properly. First, remove and check the 40A onboard fuse just left of the power/ground/remote terminals. If the fuse is OK, disconnect the speaker wires and try powering up. If it powers up OK, check the speakers and wiring. If it doesn't, disconnect the inputs and try again. Check the grounds of both the amp and your receiver. If these check OK and the amp is still not powering up properly, it's most likely an internal component failure and the amp needs service. Hope this helps.

If the amp goes into protect mode, it's likely due to shorted output transistors. To eliminate other possible problems, read through the following page:

Amp in Protect Mode - Troubleshooting

If the problems are not with the wiring, follow the link at the bottom of the page to the Amplifier Repair Primer page.

Let me know if you have any other questions.

If the fuse only blows when the amp is driven hard, the impedance of the other speakers is likely too low.

From what did the wire become disconnected (amp, battery, cap...)?

no that is not normal. That means your amplifier is still getting power. Try connecting your remote wire from your cd player, to an on / off switch (auto parts store) and from the on / off switch to the amplifier. When you turn your car off, turn the switch off and your amp will no longer have power.

Reconnect one speaker per channel and swap the RCA cables (L > R and R > L) to see if the working channel switches sides. If not, move all switches and controls to see if any are intermittent.
