I have an Eclipse SW8122 DVC 12 inch subwoofer, and the amp I currently have is not powerful enough for it. I have an Eclipse CD8052 headunit that has 8 volt pre-outs. Each voice coil on the subwoofer is 4 ohms and the subwoofer will be wired in parallel so the amp will see 2 ohms. The subwoofer is rated at 500 watts RMS and 1000 watts MAX, but from what I have heard these subs are "underrated".  My main focus is on SQ, but having a little extra SPL would be nice too.

Basically I need an amplifier that meets the following criteria:

*up to 8-volt input sensitivity

*500 watts RMS (or better) at 2ohm

*2ohm stable

*good SQ 

Any recomendations? Specific amps, or brands I should look at?

Thanks in advance for any replies.

The Alpine PDX1.600 would fit that bill quite nicely.
It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

max is a number that is made up...doesn't mean anything
I gave a 200 watt 25 dollar sub 3000 watts for a couple seconds and it lived...doesn't mean that it is rated for 200 watts rms and 3000 watts max

It's also a Class D amplifier. Don't worry about max power, ever. Forget what ANY manufacturer tells you about max numbers, they'll just get you in trouble. Alpine doesn't give a "max" power rating, so your guess is as good as mine.
That 600 watt Alpine will be a perfect match to that woofer.

Any links to any reviews on the  Alpine PDX line of amps? I am considering replaceing my Eclipse XA4000 4-channel with an Alpine 4 channel from this line so they match. Is the PDX line known for its sound SQ? I have never used Alpine before, myself. Mostly Eclipse and Clarion.

I'm a convert... I had a complete Eclipse system before, and it's now all Alpine amps...
Look up some of the threads on me, (they'll be the long ones, I think) I know there is a personal review of the 4.150 in there, somewhere!
