Oldschool US Amps HELP

[Lakota 5,000+ posts]

I just installed my USA-400 today. It's rated at 1140 brided at 1ohm (it's a 2-channel). I have it wired to 1.7 ohms bridged (according to my dmm). This thing is pulling massive current when I'm not even turning it up very high. I had a Kicker KX850.2 in there, bridged at about 4 ohms (which is rated to do 850 at 4 ohms bridged) and it didn't pull NEAR as much current as my USA-400. I was getting much much louder with the Kicker and not pulling near as much current. My question is, are the old US amps known for pulling a ton of current? I really don't think the install is a problem, I've never had trouble like this. Thanks.

Oh yeah, power and ground are fine. I got about 12.56v at the amp with the car off.

Yes, they draw ALOT of current. But keep in mind if you can supply it, they are awesome amplifiers and are still regarded by some as some of the best amps on the market.
