as long as you don't go crazy with it, you can use it. but if you set your gain right, there really is no need for it. |

Some bass knobs are actually bass boost. And that can cause problems. Most people think you your bass knob will "turn it up"...which it totally the wrong way to think about it. That way of thinking is the reason people blow subs.
Personally, I would rather put an control in-line on the RCA's. Like a Hooker Audio XRBC. That way you can set your bass w/ the knob all the way up and use it to turn the bass DOWN. |

i thought they where used for an easy convient of turning off the subs? how could it sound good then with out the bass knob? because rite now i have the kicker zx1000.1 and i have the bass knob hooked up and my gain is set half way, and i usually turn the bass knob pass the halfway mark. if i take it off how would it still sound the same? |

especially on the kicker amps. you don't need the bass knob. it makes the bass sound muddy. |

Listen to thives hes right on.........
Bass boost = clipping
Bass knob = the same thing as tuning up the BB on the amp
Set gain properly and don't use.
Now there are a few, not many, amp that have an external "gain" knob. This is also bad, as once you set the gain properly you don't want to increase it anymore. |

I use my BB on my amp, but I don't pound my stuff, ever really.. so it's okay
BB on my amp is set ~1/2, but my sub control on the HU is set below half and I don't go over half on the volume. So you could use the BB, but not if you like wanging alot |

Turn down the BB and turn up the sub level...... it will sound a lot better. BB creates a peak at one frequency (translation: sounds bad) |

bass knobs pretty much do the same thing. i have mine at like 1/8th just so if i want to turn my subs off i can have the control in the front of the car. |

Question here, Where should you set the sub level on a HU when setting your gains? In the middle? Is there a limit to how far it should be turned up to prevent clipping? |

imo everythang should be set on flat gives you a better sound.set it on 0 and adjust the gain where it should be with a dmm |

I always tell people to set their gain with the sub level on the HU all the way up. That way, the only way it can go is down, and they are sure never to clip their subs.
You CAN put it in the middle, which is where I put it when setting my gains. If you do this, you have to know how far you can turn it up safely, in other words don't have it all the way up when playing bass mekanik. Not a good idea for noobs. |

You Morons still haven't learned anything in all this time, guess I need to come back, lOl. Bass knobs and or bass boost is two totally different things. In most modern amps the bass knob controls the amount of gain attentuation. What this means is that turning the knob all the way down you effectively are reducing gain, all the way up it cannot go past the level of gain set on the amp itself. Now here is where bass boost comes in. Modern day amps have a pot on the amp that says bass boost usually centered at around 40hz, good for getting loud but sounds like crap, quite ghetto actually. This center frequency usually has a rolloff between 12-18db/octave, higher the number the less it effects the surrounding frequencies, more like a single band perimetric EQ. Now if you were to turn the bass boost pot down to ZERO, that is the magic number, you can still make good use out of the bass knob which will effectively control the gain from its set point. This is most usefull when you come across music with different recording properties which you could actively without having to run to the trunk control the amount output from the amp, turning your bass down on your HU is the wrong thing to do, all should be set flat anyways. To see if yours indeed controls gain, set your BB to zero, set your gain to 1/2 and plug your knob in. Turn the knob dial to 0 and turn your HU up to like 20. turning the knob up it should go from inaudible to audible, if it does, all is good. The only thing that makes it a bass knob is the knob adding the bass! Polo..  |

The knob isn't bad, the amount of bass boost is! Go right to your amp and notice the adjustment that says bass boost, turn it to zero now you have nothing to worry about. Polo.. |

Polo you don't seem to understand that on many amps the bass knob IS a bass boost control. On others it is a gain control.
In either case you don't need it, and in the first case it's very bad.
I stand by everything I said here 100% as well as what jake papa and Canaan posted. |

I still use my BB on my amp, but I am very careful with it as I said before I never go past half on anything really...so long as the BB isn't cranked up and you aren't jammin all day long, you will be fine....
on the other hand, I will give the proper way a try, with the DMM and all, instead of just playing conservative and somewhat by the ear |

Thieves: Do try setting your gain right, get rid of bass boost, and increase your sub level if you need to make it louder. I guarantee your bass SQ will sound 3x better with a flat frequency response. Bass boost does the opposite, creates a peak, exactly the same thing that most bandpass boxes do.
Torn:
As I said above " I always tell people to set their gain with the sub level on the HU all the way up. That way, the only way it can go is down, and they are sure never to clip their subs.
You CAN put it in the middle, which is where I put it when setting my gains. If you do this, you have to know how far you can turn it up safely, in other words don't have it all the way up when playing bass mekanik. Not a good idea for noobs. " If you do put it in the middle and set the gain, you can turn it up on songs that are not bass intense. Just don't turn it up and blast the latest bass mekanik CD..... good way to clip your subs.
HU sub level does not equal bass boost. |

BB causes a peak like he said and is more likely to clip your amp and subs. the subwoofer control on the HU does increase the strength of the signal but not as significantly as the BB does. So you are better off using the HU sub level control rather than the BB but stilll need to be careful if you set your gains with the sub level ~1/2 |

^^^^ yes exactly
The sub level control on the HU is pretty much a volume control for the subs. It increases and decreases the level of all bass frequencies.
Bass boost creates a peak at one frequency, and by doing so actually makes other frequencies sound quieter. |

Now on some amps the remote control has the same effect as the HU sub level....... but not many.
It's usually a bass boost control. |

RemoteBass(level control) with the remoe bass level control you have the ability to control the level of the subwoofers remotely by controlling the output level of one or more ZX series amps. |

That may actually be a volume level control....... do the subs turn off when you turn it all the way down? If so then it is. |

Mark, I think the sundowns may be a volume control rather than a BB control, I have an RD, which is virtually identical and when I tested out my remote knob, when it was on max it was playing at the levels I had set the amp to before I plugged the knob in. |

Yeah VT it sounds like yours is a level control not a bass boost. Which means it is safe to use, but the HUs sub level control does the same thing, so the knob is unnecessary.
"that wave thing" = an oscilloscope 
Don't take offense to this, but if ya don't even know what its called, you not going to be able to use one effectively. |
