thumbs up on the basslink... do you need RCA connections for it though? if you do you will have to upgrade your head unit.. a new headunit will get you better sound anyway, a head unit with higher output power than stock will give you better clarity at higher volumes, plus it will reduce the risk of blowing your speakers from distortion.. iirc you can find some eclipse head units that will work with the stock cd changer, i would never trust that thing enough base my sound system off of it though
