I have my MC443, that I just removed from my car I sold. I managed a store that sold McIntosh and other high-end equipment, so that's why I have it. It has run a single 8 ohm, 10" sub it's entire life in a Legend Coupe. Sold the car, kept the gear, bought a Honda CR-Z and this amp weighs as much as the motor, so I won't be putting it in this car. I was about to post it on Craigslist and Ebay for $800, it is in excellent condition and fully operational, please let me know if you have any questions. I have images of it, but don't know how to send them to you on here. Larry
