I have a new in an opened box Arc Audio KS125.5 BX2 Mini. It comes with everything it should like the high level inputs and manuals. I have one of these on my bike now and this is an awesome amp! The box was opened but I never installed it. I was trying to put two of these in the fairing and both wouldnt fit so i bought a 4 channel Focal. My loss is your gain. Very clean sounding and it is a class h so it doesn't interfere with the radio like class d amps do. These sell for $359.99 new from the store. Shipping to the continental U.S. only.
