My subs (2 audiobahn 12") are 550w RMS, single 4ohm voice coil and the amp that im looking at getting (hifonics brutis 1500) gives 500.1 @ 4 ohms. Does this mean that 500watts are going to each subwoofer or 250watts are going to each subwoofer? and do you think that this amp is good with these subs?
