I was wondering if anyone might be familiar with the zeropoint amps from phoenix gold. If so what kind of free air subs would be good with it.

I have installed a few and never failed to be impressed. They can still be found from time to time on ebay. Its always hard to find one that the plexi isn't messed up on though.
Why are you going free air when there are soo many great places ot put an enclosure in that vehicle?

An amplifier is an amp, is an amp. 400 watts is 400watts. All amps work with subwoofers, just that some do it more efficiently.
I haven't seen the ZPAs since about oh....1999 or so, but basically, they were Phoenix last low impedance amplifiers...the ones that allowed you to run them 1 ohm mono!!!! The upside was that if you were competing in the 51-100 watt range, they were rated at like 25Wx2, you could use 2 of them, yet they'd put out 400Wx1 for the subwoofers. A 'cheater' amplifier.
That would be the advantage of that amplifier, and the only one. Why? Because it's just a class AB amplifier and not very efficient. You could buy a newer Class D amplifier that puts out 500Wx1 that uses less power and virtually no heat @ 1ohm, where you'd fry an egg on one of those--and the newer class D would be 1/2 the price!!!
It's really all about how much power you want to run. If you were competing in IASCA, there was no comparison. Those amps were severely underrated. EX:
Rated
25Wx2 @ 4 ohms
50Wx2 @ 2 ohms
100Wx2 @ 1 ohm
200Wx2 @ 0.5 ohm
ACTUAL
60Wx2 @ 4 ohms
90Wx2 @ 2 ohms
140Wx2 @ 1 ohm
210Wx2 @ 0.5 ohm
OR...MONO....
180x1 @ 4 ohm
280x1 @ 2 ohm
420x1 @ 1 ohm

those things would pull some current. We had a guy with 2 0.5's in his 300Z. It was very loud but I think it metered out at almost 200 amps once..........

That's insane!!! You could take 4 or 5 people off death row with that kind of power.
