The two I know of are JL "/" series and PG Xenons. I want something that will give me > 500 watts no matter what sub (1) I will put on it. What others are out there????![]()

You must be confused.Originally Posted by FoxPro5
A regulated power supply means that the amplifier will output rated power with a wide range of power input voltages (normally 11V-15V or so).
A regulated output, like the Xenon and Slash amps use, means that the amplifier will output a certain amount of power (or close thereto) into a wide range of impedances.
For example; both the Slash and Xenon use regulated outputs, but the Slash series uses a regulated power supply whereas the Xenon uses an unregulated power supply.
But, those two amps are the only amps that come to mind that have regulated outputs.
Regulated power supply is a whole different ball game.
Thanks for the correction. Confused, I am. Let's say that if the 500/1 and the 600.1 were the same price which one would you choose and why.Originally Posted by squeak9798

I'd choose the PG. Those JL's are pretty inefficient for being a Class D design.
Would the damping factor be something to consider as well??Originally Posted by squeak9798

When you're comparing amps with similar output topologies (push pull vs. single ended), the output impedance isn't going to change a whole lot - therefore, the DF isn't really something you need to take into account much.
Seems like the Zapco Reference amps are regulated too, but I may be mistaken.

No, they don't have regulated outputs.Originally Posted by bikejunkie223
And as Jack said......for the most part, DF is not something to concern yourself with.
None of them are "spot on" as to doing exactly the same power at each impedance. The PG's, for example, put out a little more power at 4ohms than they do at 2ohms, and a little more power at 2ohms than they do at 1ohm. But all in all, the small amount of power differences aren't enough to actually make any difference.Originally Posted by DBfan187

while i don;t really agree with that statement, DF typically isn't an issue. though with some class D amps it gets pretty low.Originally Posted by Jack Frost
what is more interesting is class H amps which use the ability to change the supply voltage as a means of increasing efficiecny.
