LISTEN CAREFULLY!

Two dual 2 ohm subwoofers can be wired to a 0.5 or 2 ohm load. Two dual 4 ohm subwoofers can be wired to a 1 or 4 ohm load.

so if the sub is 600watt rms duel 2ohm you would need an amp that is 600watts rms at 2ohms, but if the sub is 600watt rms duel 4ohm you would need an amp that is 600watts rms at 1ohm?
if i am correct i have no clue why and if you could throw an article or explanation my way i would really appreciated it.

Let me google that for you

Of the original that you stated, planet audio is decent, as is Hifonics...personally, i hate power acoustic and i stay away from them...the Mb Quart that was suggested is a great value

also, if you were interested in Hifonics, the MB is from the same parent company
