Audiobahn A2301Q amp, charred RCA wires

I have a Audiobahn A2301Q amp and the internal RCA wires that go from the back side of the RCA jacks to a mini 3 pin connector and run to the opposite side of the amp were charred and shorted. The protect light is on and the amp dosen't work. If I replace those wires and connector's will the amp work again? Is there any other problems that might relate to this? Please let me know! Thanks.. Chris.

If the amp goes into protect with the wires unplugged from the board, the amp likely has more serious problems. It may have a shorted power transformer and almost certainly has shorted output transistors. If you think you may want to try to repair it yourself, read through the following page (particularly the information in the yellow box). Respond to this post if you have more questions.

No sound protection light on.


Either blown subs, or bad amp.. Disconnect the subs, and try turning the amp on, if the amp is still in protect then your amp is bad, if the protect light goes off, then your subs are bad, or possibly wired at to low of an impedance, but I don't think that will trigger the protect on an Audiobahn amp.

Hello sting_ya_sco,

The ACAP501Q has 2 sets of of RCA jacks. The first set is input and 2nd preamp outputs. The jacks are factory covered with plastic protectors. Just pull the protectors off and plug in the cables.

Hope this helps.

Audiobahn amp help...


You have a Direct Short in the System Between the Head Unit and the Amp. Check the Ground on the Amp and then Check all the Wires behind the Stereo and the Common Ground There. You could even have a Spot in the New RCA Cables that is Touching Metal Somewhere. Please Rate My Response! Thanks!

On the following page, go to the section labeled 'Checking Bipolar Transistors'. Under the two images, you will find a link to a form that will allow you to enter all of the values with the various lead configurations. Follow the instructions and send me the zipped file with the images. There's a link for my email address. Testing results are more definitive when the transistors are out of the board but initial testing in the board is reasonably reliable.
