    How effective are "bass knobs"?

    Anyone out there who'se used a remote bass knob control for a Rockford Fosgate amp? How effective are they as a volume control? Do they only work for certain frequencies, or are they good across the low end?

    Thanks

    They work just like the punch bass boost knob on the amp. It's cool to play with for a little while.

    they can be very handy, and they are good across the entire sprectrum, it just pushes the sub harder it does not change the frequency

    Can it turn the amp down to near zero if you want?

    It changes the amount of boost at the centered boost frequency ( 40hz I believe ). You can turn the boost all the way down with it. But it doesn't control the volume.

    that depends on the amp, some amps bass knob act as a "bass boost" pushing an extra 8, 10, 12db's to the sub

    Yes sir at the set frequency. It works like a crossover in the sense it has a roll off on both sides of the set frequency.

    I think we are pretty much saying the same thing just that it is coming out a little differently

    Yes sir I believe so. I had an argument with a couple of people over at carsound about this very same subject. I just don't want it to end up like that

    I'm currently using an inline volume control in the rear RCA's, for the subs. I like the ability to set bass power where I want it. But now I want to also amp my rear speakers, so I need to remove the volume control. My RF 160.2 (sub amp) has a remote bass knob, they say it controls +/- 8 dB at 40 Hz. What I'm asking is how much range is that? Would it be an effective way to dim the subs when Grandma rides with me? Or is it more like changing the equalization setting on the HU?
