I took a gamble on it at 50$
From what i can tell its an a/b monoblock style amp (not real power efficient im guessing)
so heres my concerns
does it do rated? (1500@1ohm)
does it heat up?
I dunno squat about audiobahn and even less about the old stuff, if you guys have had any experience with them lmk

if its an a/b class running anywhere close to 1.5k then ya...its going to get pretty warm.

i've never ran audiobahn anything since i've never seen anything from them i trust to do what it says and do it well.

it cant do rated it will fry within minutes
