[QUOTE="zako, post: 7878016, member: 629735"] I don't have a direct experience with either of these two amplifiers, but my gut feeling is that Alpine, when new, is a better built, better executed product. All of recent MB Quart products have obvious cost cutting in them, and FX is their lowest end line. Bump your budget a little and look for something more solid. I'd recommend to run a PPI Phantom P600.2 bridged. Onlinecarstereo.com has it for $140 right now. I have a 4-channel version of this. It runs cool and takes lots of abuse. Don't worry about fuse rating. Since you will hopefully run only 300watts to the subwoofer (setting gain by DMM might be a good idea), the amplifier will need less current than what the fuse rating may suggest. Another amplifier you can try is Boston Acoustics GT-2125, which should be good for about 400watts bridged. The GT line of amplifiers was clean enough to power full range reference quality speakers, not just subwoofers, and it was somewhat pricey. Now BA is exiting car market, and some vendors are clearing old inventory at good prices (this one is for about $125 on Sonicelectronix). The only issue is that it's a Class A/B design, so it needs good airflow about it. In my book, P600.2 is the winner though. Being only $15 more expensive, it's very small and efficient. [/QUOTE]
