I have a DSP system.

Settings:
Gain 3/4
Cross-Over - 1/2
Bass - 1/2
Bass Remote Switch - I have Bass turned up all the way

To sum it up: Treble > Bass. Meaning my speakers are louder than the Bass.

This thing is 'ok', but it is definitely not for shaking your car or vibrating your car seat.

Basically I am pretty disappointed. I was expecting there to be a lot of bass. It does add a needed improvement to the overall system.

I listen to trance music and I hear sounds that I didn't hear with the DSP system. That's the only plus.

If you are looking for loud bass then this is not for you.

However, I guess for $250 I shouldn't have expected too much.
