Default eliminating pop sound when using accessory acc as remote wire for amplifier

pop sound from speaker when i turn off car, the remote wire i'm using is from the accessory (ACC) because the factory headunit doesn't have a remote out i probed all the leads on the back to no luck so my only option was to use the acc or add a turn on switch. is there a way to remove this pop sound if the rca isn't plugged in it doesn't make that pop sound it only makes it from the rear speaker. it might be because of a cheapy line out converter i'm using for the rear line out converter because this isn't happening to the front line out converter.

You should be able to purchase a relay that can give you a turn on delay or a soft turn on.

Whats the difference between 12V from remote and 12V from ACC?

Good question Mote. Alot of amps have special circuitry to ensure "soft" turn on and turn off to eliminate popping. Maybe it is an internal problem with the amp???

Do you read 6v DC on all four wires feeding the rear LOC?
