ok so the other day i get in my car and there is no bass to my system at all. so when i stop i move my subbox to chek all conections to my amp.. as soon as i do this my subwoofer starts firing non stop so unplugged the rca cable to my mono amp( for the subwoofer) then i hear the rear speakers are doing the same so i unplug the rear rca wires to my 4 channel amp. the front speakers are working but there is a loud buzz that overpowers the music unless its halfway or over. so i unplugged those rca cables to. This morning i tried to see what the problem was and so no wires shorted or touching so i plugged bak in the front rcas and the same problem was there. as soon as i plugg in the rear rca the amp goes into protect mode and no sound at all comes from an speakers. if i plug back in my subwoofer rcas all i hear is the constand firing pf the subwoofer. can anyone help give me an idea of what to look for

 

Sounds like the head unit to me, if youre having the same problem on completely separate sets of RCA's.

 

how would i chek that?

 

get some diferent RCAs, and re-run them from the HU straight to the amps. if it still has the sound, odds are it's the HU.

 

Or find someone with the same brand head unit and plug it into your car to test.

 

is it posible its my ground to the head unit?
