I've got a 12" alpine type R with an alpine mrp m650 amp and it isn't sounding as good as my audiobahn amp sounded running this same sub...I dont know how to tune the amp to make it sound right. I know this amp has to be better than the audiobahn, so does anyone have any advice on how to tune an amp or is it all just playing with it and trying to figure it out (ive had no luck doing this
