which is a better amp for my Fi BTL the SOUNDSTREAM RUB1.2500D or US AMPS MD3D?

what type of electrical system should use keep these amps running at a good voltage?

Do you plan on running only the MD3D or are you going to also run a seperate amp for the rest of your speakers?

I planed on running a 1000C4 4 Channel Amplifier or something like it.

never heard the us amps, but I can vouch for the ruby, its a beast, and they are selling for about 450 with man. warranty. hell of a deal. the harder I push it the better it gets, still haven't found its limits, only mine so far. (i am too afraid to turn it up much more since I dont want to damage anything) it is ridiculous loud, and i am only running 2 ohm. sound quality is excellent, and it doesn't thermal at all. not too sure of its performance in 1 ohm, since my setup is only capable of .5, 2, or 8 ohm, until I pick up another pair of subs... I have noticed that since it is a regulated power supply, it will continue to put out full power regardless of voltage changes, but it starts to distort if you let you voltage dip below 12.5 or so. keep your voltages up, and this thing will absolutely slam a BTL, or even two, and sound great doing it...
