Correct.im assuming your subs are dual 4 ohms and thats why you asked for that power at 2 ohms?
I saw a wiring diagram on crutchfield.com showing 2 subs at 2ohms. I may be wrong though.Wait what? If you have two d4 subs you can only wire to 1 ohm! Don't know why you'd run at 2...it's just going to cost you twice as much money and you'd need two d2 subs.
There are a bunch of amps that'll give you 1500-1800 at 1 for cheap.
Where in socal are you?
