so im considering buying a 15" subwoofer, but its passive and rated at 400w RMS. well unfortunatley, i can't find a 400w or similar monoblock amplifier anywhere online. would it function with just 100w? that seems to be the highest i can go unless i want to buy some 4500 watt amplifier from pyle, but that would destroy it...
also if at all possible can someone show me where to get a monoblock amplifier thats not too expensive?
