[sleepyspl13]

What is the difference between POWER ACOUSTIK BAMF-5500/1D, the Power Acoustik PS1-5500D, and the Power Acoustik OV1-5500D? all have the same ratings just different pricings......is that all? :confused:

and trust i have the bamf5500 and its not even close to 5500 or the 3200 rms probably 2k rms hits hard but wish they would rate them properly but for 275 its a kill and a bag for ur buck just dont kill da amp
