After-market radio part of alarm system???
 

I have a 1998 VW Bettle 2.0 and last night the radio pretty much went up in flames. so i pulled it out and then the car wouldnt start, like the battery was dead. tried to jump it off but no luck. so today i replaced the 30volt fuses on top of the battery then got a jump. the car ran but felt like it was dyin the whole time. then i noticed the smell of burnin wires. so i pulled the radio out again. 2 mins later the car died out. so i have no idea wut to think, but my instincts point me else where other than the radio. any help would be awesome. thanx
