Hi there,
This is a simple fix and happens quite offten the reason for the amp over heating is a weak ground this could be too small of cable or just bad ground bolt make sure wire is at least 10 gauge or bigger and ground bolt is clean metal no paint around ground post easy fix that will take the problem away good luck

  • For years Kicker has always been my favorite amp. For this amp I advise against bridging two speakers to it. This amp is intended to rune one speaker at no more than 2 Ohms total. If you bridge 2 speakers to this amp, you may burn the amp up or for sure send the amp into protect mode.

Regards, Tony

The fuse should be in line with the live power cable that goes from the amp to the car battery. You should be able to replace it by buying a new fuse that matches the blown fuse. You will take out the blown fuse (usually within 2 feet of the car battery) and replace it with the new one.

Faulty RCA cables, Or worse possible solution is if your amp stopped playing when it was pumping at high volume, you may have blown the RCA connectors inside your head unit Or inside your amp. If possible try another known good working amp with the wires you already have, If same happens, try different RCA cables. If problem persists after trying these, Its your head unit RCA connecters or amp RCA connectors. To rule out your amp connectors, try your amp in a friends car if possible, to rule out your head unit, try another good known working amp in your car with the wiring you already have

Hello charlietmn,

First off you need to turn your vehicle on, turn the stereo on. Go back and look at the amp. Do you see a power light on ? Is it green or red ?
If there is no light or a red light on, your amp is not getting power or is not grounded correctly in which you can try the following:

Check and make sure your ground cable is grounded properly. It should be attached to your vehicles frame on bare metal.

You can also check your fuses, in your amp, and in the power cable for the amp.

In my experience installing car audio, those are the two most common simple issues.

Post back after you've checked the things I mentioned. I will assist you further if you need further help. Thank you for choosing Fixya and have a great day.

if you disconnect all the speaker wires then turn the amp on. if its still in protection its a internal problem in the amp and will require service or replacment

well... you have to wire the sub correctly to the amplifier to get good sound.. you could be giving it like an 8 ohm load and this will cause the amp to put out barely anything at all.. www.the12volt.com and the subwoofer wiring diagram willl tell you all you need to know...

Hello pruittdarryl,

Does the amp turn off when you remove the remote wire? If it does, then wire a toggle switch into the remote wire and just use it to turn the amp on and off. If the amp does not turn off with the remote wire removed, there is probably a short between the 12V+ and remote terminals. In that case, the amp is probably defective. If it is OK otherwise, you could still use it by putting a heavy duty toggle switch into the power wire itself.

Hope this helps.

You can buy splitters from radio shack or many other electronic/sound shops which split a male or female phono jack to separate stereo or mono output jacks. The most common is a phono jack to two separate mono 1/8" plugs. One way would be to purchase one of these, cut the ends off the outputs and strip the insulation, then use those to wire your amp. "Monster" brand puts out some of these splitters as well which use heavier gauge wire which would probably be most suitable for the task.
