2: to get the best loud sound frmo what i have what should i set and to what level eg: LPF or somethign w.e the list is on the amp website above and i also have posted in one of my post , if u can plz tell me what to do then ill be set:D if u can plz prove with something like this
LPF: 50- 90 LOL i dont know if its 50 hz or w.e but plz provide with something liek that so that its ez for u n me.

You could kill your blow your subs if you clip the amp...you clip amps when you set the gain too high. (a.k.a. "crank that sh!t up".)

Try setting your LPF to ~80hz. Set your gains accordingly...dont just gap them open and hope for the best. Put you HU to about 75% volume and turn the gains up until your hear distortion, then turn em back just a lil.
