cd skips due to sub woofer

I have a Sunfire TGIII, Sunfire cinema signature II and a Sunfire Signature Stereo amp powering my system. My subs(2) are custom built ported boxes loaded with JBL power series 12's (2 ohm). My problem is that when I get near a decent output, granted I am talking loud but not overwhelming, my cd player starts to skip. If anyone has a TGIII then you know what -30 is like on the volume control.This is where my problem starts. The room is not sealed and it is 24' x 15'. Yes one sub is 6" away from my rack but I do not have the option of moving it,And yes I did put additional vibration pads under the cd players feet. BTW it is a Rega Planet.Any help would be greatly appreciated. Thanks.

Try isolating the subwoofer from the floor, and maybe sound absorbtion on the rack side which is facing the sub. I've had a similar issue. My sub(s) are on the opposite end of the same wall as the system, and at extreme SPL's, the CDP would occasionally skip. I've placed a TeknaSonic isolation platform beneath, as well as a 1/8" sheet of lead (sandwiched with neoprene rubber) above the CDP (EAD CD-1000). This seemed to cure the problem.

If you've got the room, you might try placing a phone book on top of the CDP first, just to see if it helps. Add weight on top of that to see if the MASS helps steady the transport. But the microphonics of the actual mechanisms might be the issue, opposed to chassis vibration.

As with all audio gear, what works for me might not work for you.

Good luck.
