I have a brand new M4000 amplifier I was going to use on a build of mine but no longer need. It has never seen power, never mounted, only opened for photos. I added a photo of the internals so you can see the build quality yourself. Overall it is a small physical size given the amount of power it creates. Simply a great amplifier. Still in the original box with everything it came with. MSRP is $1,500 + tax new. I am selling it for much less. Shipping is on me via UPS within the USA.
