my amp is doing weird stuff so i bought a new one and the new amp is doing the same thing it will go into protect mode for no reason. when i disconnect the rca cables out the amp the amps red light goes really dim. when i gave it direrct remote power amp went outta protect but was really weak like t wasnt gettin full power when the subs hit it sounded messed up and the amp lights would dim big time.



what could cause all these problems? it will work and then next minute it will shut down and not work for an hour.

 

ok for some reason the positive wire is not getting power. cable is only 4 months old and is 4gauge and is mounted professionaly.
