Ive got a legacy american LA890 amp, and using it to power one sub . I havent set it up properly yet because i dont know what the knobs on the amp do. Its got:
Bass boost [0 - +18] (ive got this set just over half way_
Level [min - max] (dont know what this is)
Low pass [35 - 350] (im powering a sub so i guess i need this set up)
High pass [60 - 25k] (powering a sub so im guessing i dont really need this one as its switched to lowpass filter)
any help is appreciated

wat size sub u running?
Low pass about 120hz 8", 90Hz 10", 80hz 12" 65hz 15".
Level matchs the amps input stage to the voltage of your hu preout. Look what voltage input range the amp has, and the output voltage from your hu and set accordingly.
