hey jonny i own that same model power acoustik 980.i had to wire it to 8 ohms mono to my dual 4ohm voice coil kicker 10.that amp is not 2 ohm mono stable. if you get that 12 that viking suggested.the 4 ohm single voice coil sub.that amp will push at least close to its rated rms of 560.to it.that thing ran my 10 all day long and NEVER failed me.EVER!! if you treat them right they will last.hell i still have a hifonics vulcan from 1988.and it still runs great.very under rated at 50x2.cause it's a quality product.
