So today i purchased an new cd player to replace the factory one in the csvt. i bought the wire hook ups and all that good stuff. i remove the factory player and begin plugging in the new system. so i plug it in and put some power to it, the player lights up but for some reason theres NO SOUND! i try everything and finally give the guys at BestBuy a call. the guy tells me that since the svt has the premium sound package and a factory amp. that im going to need to have it installed by a profesional. and also im going to have to replace all the speakers!! wtf...why is this such a pain in the ass setup?!?! can anyone shed some light on this for me????
