Bronze Member Username: Krom79Lilburn, GA US Post Number: 11 Registered: Jun-07 | 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 |

I hope this helps you out good luck. Heres the link to set gain right. http://www.subwoofertools.com/forum/setgain.asp |

Silver Member Username: 2pacalypse1971Sandusky, Oh Post Number: 382 Registered: Jul-05 | make sure your gain is set to your headunits prevolts out and that is about it when it comes to the amp, do you have it in a sealed or ported box, because if its a ported box and the specs are all wrong, the sub will soudn horrible |
