subs make hu skip?

i have 2 L7's in a crv, and when i turn my subs up, my cd player skips, i recently just purchased a new pioneer 6900 HU but any reason why this happens? i changed out my ground on my HU as well

Grounding has nothing to do with why your CD skips. Think about it for about 10 seconds, and realize that when you play your system at a low volume the CD player is not skipping.. right? So what is causing the CD to skip? What is the difference that you feel in the truck from low volume to a higher volume? That same pounding vibration you are feeling - the CD player is feeling the same thing. Its skipping because the pounding vibration from the subs is causing either the CD to move, or the laser in the CD player to move, or both.

I bet if you had an Eclipse deck it wont skip , they apparently tune their laser sled to a really low resonant frequency, something like 20hz, so you wont skip it unless you can hit like 150db at 20hz which would probably be a world record.2003 Chevy Avalanche,Eclipse CD7000,Morel Elate 5,Adire Extremis,Alpine PDX-4.150, 15" TC-3000, 2 Alpine PDX-1.1000, 470Amp HO Alt.

When I first installed my Alpine CDA-9830 (factory power and grounds for car. tiny) along with the lights dimming under heavy volume and when I hit any decent sized bump it skipped, when the bass hit it skipped. I only had 400wrms on 2 10's. When I upgraded my power and ground wires for it (fused 12g stright to and from it) it took car of the problem -except for huge bumps.2013 Kia Rio -90a alternator

Mine did at first only 'cause it didn't have sufficient power. -You ever notice that when the batteries on your portable CD player are going dead, the anti-skip feature doesn't work right, like it skips worse? At that point they seem to play better with the anti-skip off. Less power required at that point. I think it's the same thing with the op's one.2013 Kia Rio -90a alternator
