Grounding amp to battery vs chassis?

Recommended Posts

Just a quick question Which would be better amp grounded to frame or the neg on the battery? I can do either just as easily because my battery's in my trunk

I personally like grounding to the chassis. Reason being is EVERY TIME I've grounded to my battery I'll get terrible whine. I actually have a charger too. The stock ground isn't bad, I'd try both and see which one you like more.

I'd ground it to the battery, if the battery is grounded to the chassis.

Hmm thats what I was afraid of when you got the whine did you hear it out of your subs?

to me it depends on the build...if its a small setup or in a car without a 2nd rear battery, the chassis is okay. I prefer to bolt it instead of self tapping screws. Id also rather go directly to the battery if you have a rear battery that is close to the amp.

Nope, only my mids and highs amp. The sub amp gave off no noise.

Yup, I never found a way around that stupid pico fuse problem.
