Gain setting problem

[djtomczak 5]

I have a Soundstream TRX 2.550 and I need to properly set the gains for my subs. I checked the sticky in this section and it says to use the frequency that the bass boosts uses. My boost is +18 from 35-80hz. So what tone should I use?? I wish I didn't have to use the Bass boost knob but I have no other way to turn the subwoofer level down as I am on a factory stereo. If I turn the bass down on the factory stereo it turns the bass down for all speakers making it sound bad.

Thanks

40hz tone is what I have used when using an O-Scope.

I'm using a dmm. Would 40 work with my bass boost? because I bet there's a frequency that rises more than 40 :/

Try 40-80hz tone.

Set it on a 57hz tone, which is in the middle of the 35-80 and I played white girl with some insane clipping. I just set it by ear on that song.
