American Audio V4000 Plus Professional Power Amp 1010@4ohm 600@8ohm Modified

  

Monster of a power amp. Unit does have some scratches and marks. Has subwoofer crossovers built in.

Full range or subwoofer options. This amp has been modified with whisper quiet fans.

I did not do the work. The amp at idle has a transformer hum. Most large power amps you will hear a very subtle hum. This will not be good for studio or theater use however for production or DJ work this will be great!
