One of these amps and 8 of the D4's in 2 ohm stereo (Each channel) seems like an awesome combo. The smaller siblings (1600 and 3000) have measured very well, and initial impressions for this guy seem positive as well.
Since I have single 4 ohm VC's, 2 amps should give me more headroom than I'll need.

It's starting to look like a pretty nice amp for the price. Looks like I may need to get a PE order in by tomorrow to get the sale.
Looks like it might be able to. From the measurement sheet "Rated power readings made with BW: <10 Hz to 22 kHz. All power measurements made at 120 VAC and 240VAC

One question though.... What relay did you use in your box?
I've used both 20A SSR and 30A mechanical. You will need a 120+V relay with 12V range turn on coils. Ideally something that needs <150ma current to turn it on is ideal too if you plan on using your receiver as a trigger mechanism.
As the others have said, no problems there running both subs to one connector for a parallel load. Edited by Gorilla83 - 7/8/13 at 11:13pm
