Alpine MRD-M1000
 

I just picked up a Alpine MRD-M1000 mono block for $100 today and need help setting it up. I downloaded the manual offline but its not very help full.
Its pushing 2 Earthquake DBX10 in a ported box. Each dbx is in a 1.75cu.ft tuned at 33 hertz.

Some of the setting I did today are:

input 2ch
gain +6db
LPF 80 hertz
SUB 25 hertz




Any help would be great.
