Question about RCA RT2300 System
So should this whole system be returned or is there a way to get around tearing it all out??? I don't understand amps. obviously.
First ensure it is not a disturbance from TV or any nearby device (eg. power adapters).
Generally , if the noise raise up in volume anthen goes it is a faulty amp.
If the problem goes as you whack (gently) or move the unit then it is a bad contact or connector inside.
If you just bought the item I would replace it, even if problem disappears by moving the device or whacking it, it means the machine has a fault that can come back in time.
If product is not brand new, but covered with guaranty take in for repairs.

Generally speaking, an amp protects itself from heat, shorts and overloads by refusing to turn on or stay on.
Overloads can be from excessive periods of high output 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 hands-on tech.
