Does the 3.1 have a subsonic filter? I was checking the manual here and didn' see it mentioned.

Are you running a high tuned ported enclosure?

i suppose his bass amp has 1 (unless it a Brazilian amp like taramps or Soundigital). if not, sum of the Brazilian amps have a high pass filter. that can be used in place of the subsonic.

hmm so the mono dont have a low pass filter?
if it does why jus connect the amp to the sub out on the deck and tune from the deck according. i tink on the deck it cross down to 25hz, 31.5hz, 40hz, 50hz etc. jus cross to what frequency you want a use the eq to get the output you looking at..

well the sd 8k has a variable hp from 20hz - 80hz. and a lp filter from 20hz- 15khz. in this case the hp on the am,p can be used as a subsonic filter. ie cutting off freq lower than the set value.

what a subsonic filter does is to cut off low frequencies that can damage ur sub when it is in a ported box. you will need this seeing dat u have alot of power and your box is tuned to 45hz. i usually set my subsonic filter around 3 hz lower than that of the tuning of the box.

if you box is tuned to 45ish u can set the hp filter to 42hz or around there and the lp filter to that of where ur mids are being crossed. let say 100hz.

i personally like having a preamp installed so i can easily make quick adjustments when i need to. like sumtimes i like loads of midbass and little or no sub. so in my opinion a preamp comes in handy for a daily driver as i cud adjust it without having to take my eyes of the road for a long period of time (as if i had to change the settings on the deck)
