I have an Alpine MRV-F345 amp that I would sell you for $150 shipped. I am the original owner, and I have the box, manual and birthsheet. It birthed at 104w a channel (rated 75x4 @ 14.4v), but is only bridgeable on the rear channels. So you can run the front components off channels 1 and 2, then bridge the rears for 300x1 for a small sub. The only thing is I lost the screws for the top cover (if you look up pics you will see the brushed silver part that says "V12" on it). I personally thought it looked better without it and leaving it off made adjusting the amp a lot easier (the controls are hidden behind the panel). Alas, I still have the cover and I'd say the amp is 8/10 cosmetically and 10/10 functional. I'm sure you could get the screws from Alpine if you really wanted. Let me know via PM...
