Already replied in the caraudiojunkyard forum. But don't expect quality for 300-400 bucks for a new 3kw amplifier. It's not going to happen. You're going to have to either go used, or go with something with less power. As mentioned on caJ, efficiency is key. What's the point of power if alot of it is being lost? IMHO, it's not worth saying, yeah I got xxxx amount of watts (doesn't mean you are louder at all). Also, if you don't have the electrical for it, meaning at least one upgraded battery and a better alt, then stick to lower powered amps as well.
