Need Amp Suggestion
 

I Have A Pair Of Infinity 6x9 At A 110 Watts Rms And Infinity 6 1/2 Components At 90 Watts Rms There Both 2 Ohms. What Size Amp Should I Use And Any Suggestions On A Brand? Im Leaning Towards Audiobahn.

PRS-D4000F is what you need if you want 4 channel :
Premier™ 4-Channel Full-Range Class FD Amplifier with ICEpower Technology
150 W × 4 (at 14.4 V, 2 Ω, 1 kHz 1.0% THD)

But, for about 1/2 that price you could use 2, GM-5200T.

The amp Tom mentioned would work nice as it has plenty of power to give you abit more head room and control with out putting un-do stress on the amp. But do yourself a favour, you bought Infinity speakers don't put an Audiobahn amp on them. Kind of like putting Motomaster tires on a BMW.

Some other large amp brand suggestions:

Sundown SAX100.4
American Bass SQ780
DD C4a or C4 (Jordy O at 2LOUD4YOU has a smoking deal on those)

Look for some thing that does like 125-150Wrms x 4 I believe MTX and RF also make a nice large 4 channel. Or like Tom said a couple of 2 channels with the same ratings.

Thanks For Your Help I'm Not Sure What Motomaster Tires Are But I Guest You Are Trying To Say That Audiobahn Ain't A Good Amp? An Advisor From Crutchfield Said I Should Use A Alpine Mrp F450 100 Watts X 4 At 2 Ohms. But You Guys Are Saying Use 125 - 150 Watts X 4. I'm New To This And I'm Confused. I Don't Even Know If The Speakers I Have Are Good They Are Just Sitting In The Box.

C4s are killer and are 2ohm stable on all channels.

That could explain it a little bit.. motomaster is canadian.. lol.. haha FInally something we have that they don't.. long live crappytire
