2 x 200 into 4 Ohms
2 x 350 into 2 Ohms
1 x 700 into 4 Ohms
BlackMaxx High Dissipation Heat Sink for more effective heat dissipation
Illuminated BlackMaxx "M" on top-plate
Crunch MOSFET's for clean, reliable, high-speed, high performance output
G-Force Power Supply: PWM power supply instantly delivers maxx current
SEPP (Single Ended Push Pull) A/B Amplifier Operation
Bass Boost Circuit for Enhanced Bass Response
Versa Cross featuring Hi-Pass and Low-Pass Adjustments
High Level Amp Inputs for OEM Receivers without Preamp Outputs
Silver RCA Inputs
Silver RCA Outputs for Amplifier Daisy Chaining
Protection Circuitry guards against: current, short circuit, or thermal overload damage

is this the amp I need

thanx again for the help guys:salute:

If I understand you right, this amp will not push the sub well. You're going to need to find an amp that will push a 2 ohm load bridged to 1 channel since the dual 4 ohm voice coils will make a 2 ohm load when run in parallel.

Yeah...find one that's 2 ohm stable...

But don't go cheap. Often, an off-brand manufacturer (blaupunkt, kraco, jensen, etc) will put 2OHM STABLE! all over their product, but in all reality, it's only stable @ 2ohms for a brief pulse of energy.

And along the same lines, it's got to be 2 ohm stable when bridged (or a two ohm stable 1 channel amp). Most amps today are ok at 2 ohms in stereo, but not 1 ohm which is where it has to be for it to be 2 ohm stable when bridged. Your best bet would be to find a class D single channel sub amp that can drive a 2 ohm load.
