I think its a JBL system if im not mistaken. I think unless you are upgrading the head unit, you shouldnt mess with the 460 watt system. I would simply upgrade the speakers. start with speakers, then decide if you wanna dump the stock cd player. I dont believe that the ohms are different I believe they are all the same, Ive personally NEVER heard of a 6 ohm or 2 ohm speaker that wasnt a subwoofer.
