Re: High Pass Filter and sub help
Using the HPF is diverting bass frequencies from your sub. Sounds like you just need to turn it down..
The level control on your amp is in the area called Amplifier Input Selection, and it's labeled Input Sens. Take note of its current position (or mark the panel with a sharpie) before adjusting it, in case you want to put it back where it was.
