You don't have enough delay time from your HU in regards to supplying power. This might help fixing that

Is there a cheaper alternative to this? When first installed this never happened. When I reapliced my wires the pops started.

I didn't check the price but it's somewhere in the area of $20.

Sorry it's $34.95.

Didn't help. Hooked to good ground. New speakers. Nothing

if the speakers are powered by the head unit directly then the problem is in the head unit. disconnect the RCA's and see if the problem persists. if it persists, replace the head unit. if it goes away then you have a grounding issue with your RCA's and they should be replaced (or tested for continuity of both shields).

i've seen head units make noise on on/off when RCA's had disconnected shields - but usually only through other RCA outputs.

the internal amp is a single unit that does everything - it too can fail, or other components associated with it can fail (caps or resistors).

Sorry to hear the PAC TR7 didn't help at all. Did they ship it overnight or were you able to find one locally? You mentioned looking for a cheaper solution and went ahead buying new speakers instead, too bad that didn't work either.

I've been there's there's a speaker or remote wire shorting out

I'll get back there and try it again.

It shouldn't be my head unit. When this was professionally installed I had no problems. I rewired my door speakers to my head unit and this started
