Re: Badcaps on car amp.
One Time, I rejected to fix car-amp because bomb-bomb noise make me crazy. I've been changed since everyone was young once and do the same thing love pop music...
they all think their amp is the best one, the old-school one better than the new one, for me just a piece of junk, when I fixed the amp, look likes they found an old lover with kinda of sentimental feeling or you being back home A runaway dog has been neutered. Sorry, I've no words!
PS: Badcaps also happened on car amp, after change all the Badcaps, all four channels working good.......

Re: Badcaps on car amp.
Did you use low-ESR units at the outputs of the DC-DC converter?My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.Comment

"low-ESR units at the outputs of the DC-DC converter?" YES, I use TV's low-ESR 105c capacitors.Comment
