I'm setting up a new system in my truck. so far I have 4g power and ground wire and my speaker wires have been ran. My speakers I have are a pair of Lanzar Max 12's (new from friend) 4 ohms 1000watts max. And I'm now looking for my amp.

My friends have 2 amps for sale, a Pyramid PB449X and a Kenwood KAC-8104D. I'm not sure about how the power ratings work and I know kenwoods are better. but the pyramid is in my price range. If i could get more, would the kenwood be alot louder than the pyrmaid?
