Help With Amp Choice

Here are two amps I'm looking at to power my future subwoofer.

(I haven't decided what subwoofer to go with yet.)

This morning I'm mounting my existing amp and crossovers and I'd like to have an idea which of those amps would be better for me so I know how much room I need to give it, since space is very tight. I looked through the sticky about amp classes and read some of the links, but I'm still not clear on what the real functional differences are, and which of these two amps would suit me better.

Get the amp that makes the power you need at the right impedance. Link isnt working for me but D class amps are more efficient.

Link fixed, sorry. The two types are "Class-bd" and "Class A/B".

Any particular reason youre looking at RF amps?

Because they match the look of my existing amp. I'll probably go with one of those, but I'm open to other ideas. Also, they can't be any taller than about 2 inches.

How much are the amps youre looking at?

How much are the amps youre looking at?

the 325.1 is $175 at Cardomain, I'm not that concerned with price, though.

How about this? I plan on getting their amp for home audio and I think $88 shipped is a very nice price for 400w @ 2 ohms.

Dimensions: 9-5/8" W x 1-7/8" H x 13-1/8" D
