Well i just boutght the KD-SX8350 about 2 weeks ago and well i have turned the sub control up to 8 *max* and well if i turn it up to like 40 and the bass hits well it makes the cd player skip but i can be going down the ruffist road and it wont skip at all lol maby the bass just hits REALLY to hard or something. but any way i like it pritty good i only have a 600 watt punch he and 2 12 inch punch HE and well i have 2 ports witch i am really thinking about putting 2 more but i dont know im thinking of just making a box that will fit in the trunk from side to side and well any way enoph about the subs. this has an mp3 audio in and a cd changer in but i ordered a plug in to my ps2 so i can get sound the dealer i bought it from told me it had aux in and well it was for the mp3 and he thought it had rca plug in's for it but it was just a cd changer and mp3 input. i dont know what to do about the bass hitting it came with a rubber peace to put on the back of the cd player BUT as most of you know that hook up your own cd players there is no place to have the rubber peace to butt up against. but besides it skiping because of the bass its a good cd player even tho its not the same one you looked at
