I give a shot to this amp for my mids and im very impressed. Sounds nice and clear. Connect 2 midbass orion at 4ohm bridge, this amp is 2ohm bridge stable and wow, used my voltmeter with a 500Hz tone and i got 40Vrms (around 400wrms). Thats more than expected. Mids start smelling like burn resin so i stopped. Review: Amplifer - Great amp still going strong.
