I am looking at Rockford Fosgates product line and i notice they sell the Power subs in either 2 ohm or 4 ohm. What is the difference between them, and which would be better. (Money is not really an issue).
Also, I was planning on getting a Power T30001bd for the amp, and the sub would be the Power T212D4.

 

If money is not an issue, why are you only looking at Rockford Fosgate?

 

There is no difference in the subs other than the impedence of the sub.The 2 ohm voice coils take advantage of amplifiers that are able to handle 2 or 1 ohm loads. Basically if your amp can handle it, you will double your power with a 1/2 reduction in impedence.

Generally speaking....there are exceptions to the rule of course

Speaker manufacturers provide you the option so that you can better match their woofers to your chosen amplifier...
