5 MB Quart RAA Amps, Mono, 2 channel x 3, Blown 4 channel

I'm selling off these amps as it took me over 2 months to get them, and now I won't even be using them more than likely.

All 3 2 channels work, mono works, all have ALL the plugs, mono only came with one on the speaker side from what I was told, remote gain control is also included with the mono. Also the 4 channel is blown. 2 come with OG box as well.

These amps were built by RF. They are all heavily underrated, they'll all do about 35% more power than rated.

I'm looking for $900 shipped for all 5 amps.

RAA1000 MONO:

The Reference Series RAA1000 amplifier from MB Quart delivers the high-end performance and reliability you need for a serious audio system. Housed in a sleek, low-profile black chassis, this mono powerhouse can produce up to 1,000 watts to multiple subwoofers. Its convenient top-mounted controls make tweaking the output a snap, while removable end caps hide all of the wiring for a professional-looking installation. Use the built-in low-pass filter to get the best sound out of your subwoofer/box combo, then adjust the subsonic filter to eliminate the inaudible, ultra-low bass that can hamper performance. You also get a set of preamp inputs and outputs for tapping into your other audio components — flexibility that means this amp can be incorporated into just about any system.
If you're using an outboard preamp or crossover, you can bypass the amp's built-in gain and crossover controls for a cleaner sound. The included remote level controller lets you adjust low-frequency impact right from the front seat. And all Reference Series amplifiers are exactly the same size, so your MB Quart multi-amp setup will look perfect.
