short answer, yes but it's complicated.
 
the fact that you are asking this means you don't know enough about electronics to go fiddling about with it. How you go about adapting it for the car will depend entirely on the circuitry of the amp, specifically the type of amp (class A, class D etc) and how the mains AC is converted to DC, and at what voltage.
 
My suggestion would be to get a PURE SINE inverter rated for your amp and hook that up to your car. Not ideal, but it is easy and will work well. Make sure your alternator can handle the extra load as well.
 
Otherwise if you want to do it properly, take it to someone who knows how to repair and modify radio electronics. Get them to adapt the power system to run on 14.4v DC (not 12) as well as add the necessary filters to shield the system from the electrical noise in the car.

Thanks for the somewhat condescending remark, but you're a bit late to the party. All ready sorted it and yes it works very well.
