Default Stereo no sound from speakers

I have a 2011 Flhtk. Stereo sound cuts out random. J&K 500 watt amp and speakers. Amp shows no sign of overheating. Green light stays on. Hit speaker switch and will sometimes work but not for long. Now no longer works. No codes on raidio. Any help please.

The radio is most likely broken. You have a couple of options:
1. Send it in to be repaired at Iron Cross Audio. Expect to pay at least $250.
2. Repair it yourself. Or if you do not have the ability, maybe you can find someone. Cost would probably be under $50.

Here's a parts list of items available from Amazon:
A. TDA7563 STMicroelectronics Audio Integrated Circuit New, from Amazon
B. Innovation Cooling Graphite Thermal Pad (30 X 30mm), from Amazon
C. ASI 388 Clear Electronic Grade Silicone, from Amazon
D. MG Chemicals 422B Silicone Modified Conformal Coating, 55 ml Bottle, from Amazon

3, Look into replacing your radio. If the CB, Intercom, Headset and rear speaker volumn adjustment features aren't important to you, you should look into the new Rockford Fosgate PXM-HD9813 radio.

Yup. Trouble shooting mode. Could be anything. Start by isolating the HU and the amp. Then if the HU works trace every wire from the HU and battery to the amp. One loose connection will jack things up. Then track amp to speakers.
But make sure ur prob isn't the speakers themselves when u run HU yo speaker.

You may want to start by rewiring all the connections from the HU to the amp to the speakers. Likely something not making a solid connection. That is a cheap and easy task and you may not need to go any further.
