Hello I have a rockford t1000.1 bd works fine but when i turn the knob it doesn,t work bass stays at same level lights on the knob are on any input thanks.
are you using the correct 3-pair cable? or just a cheapie phone cord? also, what is the model/year of the t1000.1bd? the first bigger ones can use an older gain knob, but the newer ones need a punchbass knob/dual knob, and i don't know how far back the newer knobs can go either....
