I've got a focus 2001, with a SQ HDS310, its really nice and hits alot harder than it sounds to, which is better in my case cause i dont like pissing off other drivers.
Anyway, yeh that should be fine, as long as you run 0-gauge power wire. Technically, my battery shouldn't be able to handle the ratings on my 2600watt planet audio, but it can without a capacitor, and my lights still don't even dim. I can blast it up as loud as my unit will go, full bass boost and it still doesn't dim on me,
So the i'm guessing the rating on the sub is a bit higher than reality.
So it should be all good, its a very accurate sub, make sure you box it properly, they recommend a ported ~3.4 cubic feet with like an 18" port,
Or something like that, i'm stretching it in my 2 cubic foot 14" ported box. But it still sounds great. I can pm you if you have more questions, just pm me first.
