help! sub is poping

[Sid420]

It does it about every 20 seconds or so after I started the car. It looks like the sub goes in then pops out then 20 seconds later same thing in and pop out

[Weigel21]

So it doesn't do it with the ignition in the ACC position?

[Sid420]

Yes it does.

When I turn my car on my subs will pop twice but I have the amp all the way down and the hu all the way down. I checked my rcas and everything but nothing seems to be different then my last system which is using the same wires and they never popped. Help please

Does the woofers pop when you change tracks on a CD or change sources on the unit? Usually it is caused by the amp turning on before the units line outs are activated. In your case, it pops every 20 seconds indicates a bad head unit ground/bad amplifier ground/bad rca/bad amp. If you unplug the amp RCA's and power the amp back up, does the woofers still pop? If so, get a DMM and test amp ground continuity if it is a good connection and your terminals and ground are solid to the point where you can't move it without tools then your ground is probably good. If the amp is getting 12.4v+ on the b+ & 12v+ on the remote then your wires are good. Probably a bad amp.

So I took the speaker wires out and now the amp is in protect mode

[Sid420]

I think I have a bad amp. I put my other amp and works like a charm.

bad amp or head unit.
