AMP Tuning
 

hey guys whats the best way to tune your amp to your sub..im pushing a 2500watts autotek mean Machine..pushing 1 HDC312 sound qubed,in a 17x23 box with two 4'' ports 18" long.

xover : around 80Hz low pass
Subsonic : around 28 Hz
level (gain): read up on how to set your gain with a multimeter.

My amp has a bass knob how should that be set

That's a bass bost knob, set and use it moderately if you have to, most people dont really use it..

Mine is set with a DD-1 SMD Distortion Detector DD-1 - SMD Distortion Detector - SMD Install Tools / Electronics

I found this amp gain setting chart would this work my amp is 2500watts and my sub are running at 2 ohm
