Just a quick question... Where should my sub amps LPF be set to. The installer left it at like 125 Hz, but that seemed a lil high, I lowered it 80Hz but i feel like im losing some bass. I have two 10s and an alpine amp in a ported box. What does everyone else do??? Thanks

 

80-90 should be fine, if you raise it too much it will pull the soundstage from the front to the rear.

 

80 is fine, but it's always where it sounds good to you - take responsibility.

Is it a switch or a knob? If it's a knob, you can experiment a bit, because the labels don't correspond precisely.

You did lose some volume, but no LOW bass. You might have to bump your output gain a bit to make up for it.

 

It's always a taste thing. In one of my previous vehicles, believe it or not, I set the low pass to 80Hz and the high-pass to 120Hz. Technically this is bad because nothing was set to respond between 80 and 120. However, if I let either set of speakers hit those frequencies, on certain songs, the bass hummed very irritably. I figure the cutoff is not hard, it's a slope, so even with those settings I was still getting those frequencies a little.

Anyway, I said all that to say don't worry so much about what the "proper" setting is, just go with what sounds best. I personally don't like hearing much mid bass from a subwoofer because it hums to much.

 

really depends on how low your mids can go. a decent 6 1/2 should be able to hit 80 hz, so I have found that to be a good starting point. jps
