I just got my PSW650 back from the CC. I have owned this sub for 3 mo but its been in the shop over 1 mo. The first time I took it in they said the amp was bad & ordered & replaced the amp. Took the sub home & it still didnt work. I took it back to CC & they checked it again & said the fuse was blown & a lead or somthing was also burnt, so they ordered another amp & replaced it again. I was told I should run the sub on a seperate AC line by its self. Is this correct? I replaced the 650 with my carver when the 650 went in for repair, & so far I have no problems, its pluged into the same outlet (power surge) & uses the same cables. Dose a sub need a dedicated ac line? I have never tripped a breaker in my homes breaker box. I think that my system although it is plugged into different outlets runs on the same circuit. Any info is appreciated. Do I need a line conditioner or voltage stabalizer, or somthing else?
