I have an MTX 4002. does 200x2 @ 2ohm and 100x2 @ 4 or 400x1 @ 4 bridged. does more than rated as well. let me know. ill let it go cheaper than your wanting to pay. Very solid amp.
Brand new in box. AURA AUDIO systems RPM stage 2 2300. Does 150+ x 2 @ 4ohms. 600 x 1 @ 4ohms.. underated. new with bass control knob. $100 . Made in USA. AURA was a high end speaker maker few years ago. Not some junk amp.
I am not going to use it. still in the box. complete.
