My amp comes on for maybe 2 seconds and the yellow light that says thermal comes on and goes off. I dont get any sound. This anp is on my highs, but I dont get any sound out of the amp on my subs either..
There are some things I want you to check, 1) Make sure your ground is good and I mean very good, 0 ohms resistance to the negative battery terminal 2) Make sure that your AMP is grounded to that ground point you checked in step 1. 3) Make sure that your power supply B+ wire is one continuous run no taps or spliced connections. 4) Your speakers and woofers are all properly impedance matched to your amplifier (if your amp is 8 ohms then your combined speakers impedance must be 8 ohms total). 5) voltage regulation to amplifier is good. 6) Check all connections and ground points again After these items are done power on your unit and then see if the problem happens again, if it does the issue is inside of the unit, one of the internal components has gone bad and you will need a schematic, a multimeter, and an audio tracer to work on the AMP with.
