I currently own 2 Polk SR124dvc's powered by a Polk Audio PA1200.1 amp. I'm not so great with tuning the amp and was wondering what my filters settings should be for the following:

Gain
Subsonic filter (on-off)
LP filter (30Hz - 250Hz)
Phase (0 - 180)

    I'd say set the LP filter to 120-150Hz or so. Then just increase your gain slowly till the subs sound a little distorted, and then tune it back just a smidgen. I'm not too sure about the subsonic filter. I think if your sub sounds sluggish or out of time you can switch the phase and see if it sounds better. I know there will be more in-depth answers coming but these suggestions should get you close to what you want.

    Low pass filter set to 80 at most then adjust down from there. 80 Hz is where bass starts to become boomy and easy to localize.

    Turn the subsonic filter off.

    Phase depends on where your subs are mounted. If theyre facing the rear of the car try setting this to 180 and see how if the bass output increases.

    Set the gain to around the 10:00 position.
