I am looking for an amp between 150-200RMS x 2 at 4ohms for CDT ef-61 components. I am looking to spend under $200. Which of the following 2channel amps would you recomend? Might I be better of getting a 4channel and bridging it? I am open to other recomendations. Thanks for the help.

Power Acoustik OV2-820 http://www.poweracoustik.com/gothicseries.html
4 Ohm RMS: 180 x 2 Watts

Kenwood KAC-7252
170W X 2 RMS (4 Ohms, <1% THD+N)

MA AUDIO HK798 http://www.maaudio.com/productview.cfm?pid=2369228
2 x 200W RMS @ 4 Ohm

Profile AP1200 http://www.profileusa.com/products_amps_ap.cfm
RMS Output Power(4 Ohms)-200 Watts x 2

Directed Audio A802 http://www.directed.com/audio/amps/default.asp
150W x 2 at 4 ohm

Soundstream Xstream XTA600.2 http://www.soundstream.com/sub/prod...ps_xstream.html
4 Ohms Stereo: 150 Watts (rms) x 2

that's a pretty big sized (power wise) amp you're looking for

Yah... Finding a 2-channel fo under 200 bones that puts that much power into 2 ohms might be difficult... I think you're better off going the 4-channel/bridged route.

I want to run the comps at around 170W. I don't think 200 will be too much as long as I set my gains right. A little less (150) won't be too bad.
4channel amps I have been looking at:
MTX 3404
JL e4300
Soundstream XTA360.4
Orion 4004
Kicker KX350.4
Diamond Audio 3400.4

The profile HA 1000 puts 160x2 at 4ohms. It is like 90 bucks.
