Question about JVC KS-AX704 Car Audio Amplifier
When you put power to amp protection light comes on and it makes a clicking noise.
Sounds like u have fried your amp. U didn't mention if u had speakers hooked 2 the amp. If u do, disconnect them and c if the problem persists. If it doesn't, u may have crossed speaker wires or fried speakers. I f it doesn't ur amp is more than likely fried. Sounds like that clicking noise could be the output circuit protection switching on and then off when it detects a short or problem.

Sounds like you have blown your amplifier. There could be severqal causes for this happening. Take it to an electronics repair shop, but honestly you might just be better off replacing it altogether.

Generally speaking, an amp protects itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.
Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.
You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.
If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.
If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.
