i don't have a parts car to get another unit out of...but vines makes it sound like all i have to do is find a unit with the same color and shape plugs from an e32 or e34 and swap units, even if the part number is different. i've found another unit on ebay that has the same shaped plugs as mine, but has a different part number. i know that a number of companies made the amps (like blaupunkt, alpine, et cetera), but mine says "assembled in the USA", which leads me to believe that it might be an oddball (would assume blaupunkt=germany or france, alpine=japan). can anyone enlighten me? thanks in advance.
