Amp goes green at first then protection.


check the impedance load or try a different ground. when you hook your ground up always make sure you sand the metal down before you connect to ensure a good and clean connection.as for the impedance, make sure your subs are wired to the right ohms. for example, if your subs are wired to 2 ohms or even 1ohm, and your amp is only 4 ohms, then it will do exactly what your saying it does.

Got a red light on amplifire how do you reset amp I have an Insignia NS P2000 I believe with two 12-inch Insignia subs & I have a similar problem with the indicator showing that the amp is in protection...


Have you tried turning your gain down a little and then slowly turn the gain up while the sound is on!!!! There could be a pinched wire in you speaker wires!!!! Make sure your remote wire is not touching any metal or ground wire!!!!

Red light


something is shorted in the circuit, or your subs. unhook the subs first and try it again, if it is still in protect then it is most likely the output transistors.

Power light


This could be a DC offset condition. Check you manual for what this means. Or other condition. First Disconnect the Subs and try it. If it still goes red then disconnect the RCA's and try it again. If the Led continues to go red after the click then the Amp is hosed. The Click you hear is an internal relay that cuts the subs in after a dely so you do not get the turn on THUMP of the radio at your subs.
