you should test the voltage of the amps terminalsOriginally posted by F150Matt Yea as soon as I crank up the amp turns on and both the red and green lights are on. Then a few seconds if I have ran the truck recently or a few mins if its been sittin a few hours the red light clicks off the green light stays on, the subs make sound but dont really hit for a sec or two then they kick in and start boomin. I dont think its voice coils on the subs because they push in and out just fine with no friction. What do you think it is?
