Amp recomendation for 2 set of components and sub

I have to sets of diamond audio coponents S500s and S400s Rated at 150rms and 100rms repectively. I also have a M6 10D4 on the way. I need two awesome amps to power my speakers. What kind of recomendations can I hear from all of you? I have been looking at Crossfire and U.S.Amps.

The thing that concerns me about the U.S.Amps is that ther are rated for 75x4rms and cost $549, yet I have been told by salesman that the rateing is a modest number. Would I be better with a crossfire 804a? Or something else all together.

For the Sub it is rated to take 800rms and the U.S.Amps is rated for 600rms, but the salesman says that it is the punchiest amp he has heard . . .

I want loud, but moreover I want quality of sound!

for the speakers, since they need 150/100w rms id say go with 2 2channel gonna b hard to find a 4chan that does 150w rms

and what does the salesman mean that the us amp that is rated at 600w rms is the punchiest amp he has heard??? underrated?

thas jus my $0.02

thezeb.com hifonics falcon 140x2 i think i got mine for like 99 bucks, so i guess you could get 2 of them.

Kicker 700.5

will do more than enough for the front stage off a class A/B design, then have a class D sub out with 400 watts, built in SSF, remote gain and fan if the amp sees to high of a temperature. Four way adjustable bass boost and settings for the front stage as well.

US Amps are great amps (some of the best on the market), and are very underrated. Great choice.

You also may want to look into the Zapco Reference series of amps. Also, look into Tru Technology (www.trutechnology.com).


Another thing to remember, is that your amp doesn't need to be the exact same RMS as your speakers. 75w on each of the 4 of the interior speakers will more than likely be enough, and power needed for the sub will be box dependent.
