WTF! I have a Audiobahn A8000V running it at 4 ohms(400wrms). Toady I had to stop because they are doing some road construction and while I was stopped I was thumpin Living right by B.G.(Song bumps good) and I noticed the volt meter dancing from like 11V to 14V each time the bass hit. At only 400WRMS!!! I heard that amp takes 20 amps to work, but it taking way more? COULD IT BE A BAD GROUND?
