Engine noise with Kicker zx700.5

[Rob09rrrr]

I just got a new system installed in my car and the amp is allowing engine noise come thru the speakers every time I accelerate. I do have a capacitor and it is grounded. I was told that is a normal sound on the kicker amps. I don't think its true. Does anybody have any ideas on how to fix the problem?

My car & system: 2004 Toyota Camry LE

JVC Kwavx800 in dash dvd receiver

(4) 6x9 Polk Momo speakers

Kicker cvr12 sub

Kicker zx700.5

Thanks

reroute your rca cables or use a ground loop isolator.

check your ground, ditch your capacitor... we need a sticky for this crap...

this is worse than "does RE/FI have a website"...

I just did search and this is the first thread I found with ground loop in the title so here goes. I got the same amp and get no whine through the sub channel but I do the mids and highs. Same thing? Check all my grounds and that? I doesnt do it when my mids and highs are running off of the deck. So I can pretty much figure its the ground for the amp right? Btw I'm running a 880 prs for my deck.

any noise that is associated with the engine IS A GROUND PROBLEM.

so yes, you have a bad ground. and no, we cannot tell you where. check them all.

dont rule the hu out. grounding the rca's at the hu could possibly solve the issue.
