System shutdown pop through sub.

[ultimate157 5,000+ posts]

I just installed my sub and amp into my 98 GC. Whenever the system turns off, I get a loud pop through the sub. mids and highs are still stock running off the HU until I get time to install my CDT's and their amp.

I have kicker 1/0 running to a distribution block, then 4 gauge to my amp. I have the ground 4awg running to a ground distribution block, and 1/0 grounded to the chassis by way of a sheet metal self taping screw. I removed all paint in the area with a drill wire brush attachment.

Ideas?

The word PIONEER in your sig makes me think its the deck //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif another casualty of the bad ground on the RCA's perhaps?

I assume you're using the remote wire from the HU to turn the amp on and off?

Yes. I have already fixed the rca issue with some wire. I never had this problem when the system was installed in my other jeep. Well, I did for a day or two and it fixed itself.

I would try disconnecting the RCA's from the HU and see if it still happens, if so, disconnect them from the amp and try again.

Wire your head unit same way you wired your amplifier. Directly to battery or at least ground it directly to chassis. 10-12 awg is fine. Your problem is likley a result of your head unit having to share it's ground.

Where on chassis did you ground amp? When you say, "I used a sheet metal tapping screw" I wonder if you grounded to secondary chassis like the rear deck or trunk lid.

Nope, underneath the rear seat I attached it to solid body.
