these kicker subs go quite ok, got 2 myself, so i dont need to buy them, but yea, they've done me good.
they're around $220 each new, without a box so the price isnt too bad either.
They are a dual voic coil ratted at 400rms each
are your dual 2ohm, or dual 4 ohm?
*has distant thoughts about 4 subs...*
