it would be fine, but i question the quality of that amp

 

yeah, i know what you mean. But my friend ran 2 12 polk momo's off it, and said theyre great. I wanted something like mtx or JL, but i just dont have the money for them. Thanks.

 

as a rule of thumb, dollar per watt

and I personally woulnt run that amp @ 2 ohm load bridged

i take it you changed your mind on the sub too

 

yeah, went with a 12 type r. And what do you mean 2 ohm bridged?

 

well the type r specs yu gave said dual 4 ohm voice coil. 2 ohms or 8 ohms. paralell or series.. 2 ohms give you more power (so to say) but the amp will work arder, and I question the ability of that amp @ 2 ohms for too long

 

ahh, i think i know what your saying now, well thanks for the hint, i guess ill be doin some more research.

Thanks.
