Need the perfect sub amp for 12" xplore 1200 watt sub @ 4ohm?

I have a Xplore 12" sub that I have currently hooked up to a house stereo....I need the right car amp to power it without the cause of a burnout. The subwoofer gives out 1200 watts peak power at 600 watts RMS and at 4 ohm. it is a dual voice coil sub and i need a amp that can give out at least 1200 watts but split it into 600 watts to each coil....and i'm on a tight budget.....any suggestions?
