wow... ok.... there will be a knob on the side of the 2200 that will say subsonic, use a flat head screw driver and adjust it to a little under your box tuning. Then, about 3 things to the right, there will be a knob with LPF over it, adjust it to 70-80hz. theses "knobs" are where the bass remote plugs into the amp.
try reading the amps manual.
