A NOOB Simple Question

I usually dont use a bass knob but i was wondering when you use one, does it adjust the gain on the amp or the bass boost? Im guessing the bass boost but jus would like to know.

It controls the gain, to some extent. Most can be used as a simple volume control, and turning it all the way up will not overpass where the gain is st on the amp.

k so it turns up the gain and not the bass boost. Then im going to put it in tomorrow.

it depends on what amp, though.

kenwood amps actually have bass boost center frequency and boost on the remote.

and some actually over-ride the gain controls (bad) instead of just attenuating (good)

Did your US amps amplifier come with the knob...or did you have to get it as an option?

So you guys turn yours all the way up, then gainmatch the amp with a MM, then when you want to turn it down you just turn the bassknob down from full?

Do RE12.1's come with bassknobs? Viper 1200.1s?

Yes, thats how you would do it.

I dont know about the 12.1, but the 1200.1 does include a bassknob...

i think xlube's right, it depends on what amp

Some have a bass boost EQ, like the JL slash series amps and Rockford Fosgate amps.

Some are an external gain control, like on the Kicker KX2500.1

Two different things. Although, if the Q is adjustable on the EQ, you can set it wide enough to act very similar to a gain knob.

Use it and run a test tone at 50 hz and find out where your head unit clips then back it off 1 notch then turn up your remote thing and see if ya get the rated power the manufacture said, you should, since the term "rms" is really a continuous sine wave and that's how they measure amps if ya didn't know //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif.
