I know that there are many amps in this range out there. I'm looking for the one that will only use about 15 amps and power a sub. I don't have a lot of battery power available.
vfl 1880 will give you alot more than 200 rms tho.and they are 40 amp fused i believe ,but if you run it at 2 ohms power for 500 watts rms it will use only 20 amps
The smallest mono amp I have is the Massive Audio BX2. 6.3" x 5" x 1.6" 480W x 1 at 4 ohms. It takes no larger than 8 ga power and ground wire. Off battery power it will make less power, of course, but it's very efficient.
