Question about Car Audio & Video
Un hooked checked all and it won't even turn on in the green even with the ground power and remot r only the last time it had speakers hooked up it made a thump beat that was not music like a heart beat
That thump beat was called motor boating and is amplfier oscillation. It means that a driving transistor in the audio output circuit is bad. You will have to send this in.

could be low current ,disconnect all power including ground for 20min N.B most amps will seem to be shorted at output but this is normal due to damping ratio.

It probably has shorted output transistors. To eliminate other possible causes, read through the following page.

SOURCE: amp goes dirctly into protect
ok well it could be two thing wrong your amp dont have a good ground or your amp is a smar amp and your subs must have to be hooked up so the power from the amp cn go to the subs so the amp can see that you do have subs hooked up to take it out of protect o and look at your fuses to to smal or to big will send it to protect to
