Backstrap the cd player, this is a pain in the butt to do in most newer vehicles but may be the only way to solve the issue. If this does not work, then it may be voltage related (doubtful though) but more likely is related to the subs itself. What happens is simple, a laser sled has a resonant frequency, say 55 hz for example. If your subs hit this frequency with enough amplitude, it will cause it to skip. This is not a design flaw but is standard practice. Most of the "meat and potato" lines of cd players are built to hit the price point, this means that they are built for the average consumer and not the die hard bass fiend who is trying to **** air out his lungs with his subs. If this is the case then I suggest a couple of things. One is the new MB Quart NRA450 marine cd player with a 30 second anti skip buffer - problem solved. Second is find a old Panasonic Rebel Gear cd player with a 10 second anti skip buffer - problem solved. Third, upgrade to an Eclipse that has a laser sled with a resonant frequency of 19hz and servos that react instantaneously to situation just like this.
