Spec's: Sub Pioneer TS-W300R, Amp Bazooka ELA150.1, Box 1.25 cu. ft., Speaker's Stock, HU: Kenwood KDC-MP2035

Question: What should I adjust the 3 control's on the back of the amp for. There I think is Level, X-Over, and Bass Boost. Thank you.

 

Also, what is the maximum amp I can get without upgrading the alternator and batterys.
