When I turned down the bass a bit from the HU (and increase the output to the sub a bit), I notice the sub produce sharper (cleaner) bass. All along I was turing it up to get more. It seems like the opposite works better.

Anyone else notice that?

 

This is because something in your signal path is causing distortion. It could be the headunit, amp or sub.

 

I'd bet that the Headunit is the culprit.

I remember reading somewhere that it is best to leave the bass on a negative setting. I think it was the Car Stereo Cookbook (FYI).

 

Are we talking bass and treble control or sub level?

I always kept bass at 0, and use sub control for more bass.

Doesn't make sense without further information. Most Bass ***** on decks give a gain in the 250 Hz and up region. So it affects mid bass more than subs.

could it be the gains on the amp are set to high?

(not sure...just an idea)

That is possible. Turn the bass to zero, and zero any other equalization. Set the gains to about the half way point for starters. Put sub level at 0 and listen. I normally listen to the sub and midrange components seperately when I am looking for distortion. If you are using the bass control, then don't(*slap* bad basshead ). As said earlier the bass control will send more midbass to your components, and you will end up with massive distortion.

 

I think that your wrong with the 250 hz thing, when I didn't have a sub I would turn up the bass on the h/u and then change the crossover and there was way more bass below 60hz with the bass on 7 then when the bass was on 0.

It could be that when you turn it up the distorted bass is coming from your components, because the h/u is pushing the bass all around.

I think he is probably right. First of all he did not say what the q was for the boost. 60hz is 2 octaves away from 250, so this is within reason. Second, the people that use bass boost normally don't have subwoofers. Since components can't play well below 100 or so, if you want it to sound bassy that sounds like a very reasonable place to put the boost.

 

i would happen to me with certain subs....maybe its your amp it might be maxxing out but then again i am a audio noob.
