Question about JBL P80.2 Car Audio Amplifier
At random times my Amp will stop putting out any sound. The green LED turns off and the red LED lights up.. The amp will output sound at a low volume then when I turn it up it cuts out back to the same problem..
However this problem is not consistent and randomly comes and goes since I have recently re-installed it, it can be working fine then the problem just occurs again, and randomly fixes itself after a while ! Anyone any idea's how I can stop this problem occuring ?
I had an amp that did that for a while before frying. its possible that it could be overheating causing it to go into protection mode which can be fixed with a cooling fan or remounting it somewhere else so it can get some air. it needs to be mounted in a way that it will have at least 1/2" clearance under it so it can have plenty of airflow. the other thing is you may be putting too much of a load on the amp causing it to go to protection mode. check and see how u have the sub wired and if the amp is stable. if u have the sub wired at 2ohm for more power output and the amp is only stable at 4ohm, then the amp will overload and cause the problem your experiencing. thats what happened to my amp. i had it wired for more than it was stable for and it fried
