This is a Nakamichi car stereo CD player, the MB-75. I love Nakamichi products, and I was planning to install it in a car I got at the time, but due to circumstances, I'm selling it to clear out my storage. It's a head unit designed to be used with a separate pre-amp and main amp, but it comes with a power amp unit, so it can be used as is. The 6-disc CD changer has an error and I think it needs repair, so I'm selling it as junk. For those who love Nakamichi's sound quality, please consider it. Please make any price reduction requests through the price reduction request feature.
