Please help! Car turn off "bump!"

[Twistid 5,000+ posts]

I installed an epic 160 a while back and ever since then when I would turn the car off my subwoofer would give a hard bump. Well today I opened up the Epic and changed the jumpers for ground options they had like "Isolated, Ground, and 200 ohm," options and none of them worked!

How do I get rid of this problem //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif !

turn down gains or you can put a switch on the remote wire so you can turn off the amp first.

You could solder a 10k resistor from your RCA line to ground (you could make this mod on a ghetto piece of RCA cable first to see if it works... line is the center while ground is the outer part of the cable). That should give the DC bump a place to bleed off to.

If I install another sundown 1500, will this make the bump that much worse? Will it damage my sub?
