selling my trusty old memphis 4k, i purchased it blown about a year and a half ago, sent it to db-r who said it blew because of a vibration issue with the vertically mounted fets IIRC and that he corrected that issue so it wouldnt happened again.
its been rock solid in my setup, daily at 1 ohm for the last year, with a 240a alt and 3 134ah c&d batteries in the rear to keep it fed. only been in protect once, and it was 110 degrees outside that day, went into thermal after i was beating on it a while.
amp is missing the endcaps. 550+ shipping
