yeah its a stock head unit. and no he didnt admit to doing anything wrong, just admited he was wrong in blaming the head unit was messed up. i dont think he did anything wrong either, the thing he told me about was happing before i took my car in, its the reason i got new speakers, i thought it was beacuse my stock ones blew or something. soo should i get it rewired? its bugging me sorta that i spend like 60 bucks on speakers and cant even bummp it... but the guy said it might not even fix the problem
