Hi all, I have a Profile Mono-block driving a pair of Sony 12" Subs @ 2ohms. Power is taken from the battery via a 5AWG cable and grounded at the cross-brace at the back seat. Grounding resistance is neglible when checked with battery neg terminal.

The problem is there is always a few "pop" "crack" sounds whenever the system is shut down be it turning the stereo off or turning off the car ignition directly. Are there solutions to this problem? :confused:

5ga is tiny first of all, I wouldnt recomend that.

But as for the popping, that sounds like a low quality amp.

You can also try moving your ground to another location and make sure the connection is BARE metal and clean, and tight.

....The popping is your amp turning on and off. What kind of head unit are you using? On my Kenwood there's a wire for "remote" lead AND there's another wire for "soft turn on" lead which gradually turns the amp on and off instead of "flipping a switch"....On my C.D. player the "remote" lead is the blue wire with the white stripe and the "soft turn on" wire is pink with a black stripe....If your C.D. player doesn't have "soft turn on" feature i don't think there's much you can do..but..get a new one:D

My Clarion and JBL don't do that. I'm not sure if it did with my old JVC unit I had a couple years ago or not. I paid $342 for my Clarion, so it ought not to. Doesn't on my friend's older Sony with a ~15 yo Coustic and ~3 yo Rockford amp.
