sub/HU tuning

[starfish]

The system is coming along well, i'm doing more in depth tuning now.

I have the 9887 Alpine HU set at: 3 way (active front)


80 12 Db
80 12 Db

80 12 Db
80 12 Db

4k 12 Db
4k 12 Db

4k 24 Db
4k 24 Db


I have the sub channel set too mono

Cadance a7-hc amp 0 degress polarity

I have a filter on the amp, were should i set this?
LPF.


The subs (3 JL w6's) in sealed box
sound good, but don't seem too play the tight bass as well
as the booming bass. Also i'm not sure they are loud as i would expect
for 1200 watts rms. (1 ohm)

I have the HU set at L/H

Also could use some tricks too get better MID bass from the PG RSD's comps.


We are tunning now, and suggestions on tricks too dial this in a bit better
would be a huge help.


Thanks all.
