Good morning. I've been reading the forums for a few days now and finally joined. I was wondering what are the thoughts between getting one of the following:

AddedBoston Acoustic gt-2125$123

RMS Power Rating(CEA-2006-A):

Bridged, 4 ohms: 400 watts x 1 chan.

Bridged, 2 ohms: 600 watts x 1 chan.

RMS Power Rating(12V):

Bridged, 2 ohms: 475 watts x 1 chan

New MB Quart FX1.600(around $100 with 1 yr warranty, $114 with 3 year warranty)

Class AB

RMS Power Rating:

4 ohms: 300 watts x 1 chan.

2 ohms: 600 watts x 1 chan.

Signal to noise ratio: 95dB

Variable low-pass filter: 40-300 Hz

Subsonic filter: 10-40 Hz

Frequency response: 10-300 Hz

Used Alpine MRP-M500(History unknown. $101 but has a 2 year warranty for that price)

Class-D (Digital) Amplifier Type

RMS Power at 4 ohms: 300W x 1 (1% THD)

RMS Power at 2 ohms: 500W x 1

Signal to Noise: 100dBA

Adjustable low-pass filter (50-200Hz, 24 dB/octave)

Subsonic Filter (24 dB at 15 Hz)

Frequency Response: 20 -200Hz (200Hz/-3dB)

The setup this will be used on:

DDX-418 head unit

One Subwoofer: Infinity 1260w in a single sealed enclosure RMS: 300 watts Impedance: Single 4 Ohm

Could switch to a 1262W if it would be better/beneficial. Specs are the same except for Dual VC instead of single.

Any feedback/suggestions are greatly appreciated. I've only been given about $100 budget for the amp so those two seem to be decent. I'm only looking to fill in the low end, nothing more.
