I'll chime in on the JL amps.... I run them and they pretty much kick ass. JL put in a feature that makes the amp put out the same power no matter omh load so 1.5 to 8 ohm same output. As far as ratings go when JL says 500/1 its 500watts rms and then some. We rated 2 500/1's on a meter and they came out at 695watts and 714watts. I hear that the classAB amps(300/2,300/4,etc.) rate about the same way. So if you use a 300/2 you'll probably see about 200watts per channel. Best part is this amp is small compared to other amps putting that much out. I happen to also like the PPI amps and i hear good things about P.G. and kicker. Keep in mind not all amps put out good clean power below 4 ohms. I just went to infinity kappa's on my tower and I have a 300/4 ready to pwr them. Is that enough? I'll find out this weekend, just remember that 200 watts to one guy might be different to another. If you get a good amp putting out a true 300watts at 2 ohms to 1 speaker that speaker is gonna be toast( a few speakers can handle that but not many), 300watts at 2ohms to 2 speakers is only 150 watts to each speaker( more then enough most of the time). Bottom line with JL amps ohms don't really make a difference. Hope that all makes sense?
