Car audio question: High pass and Low pass filters... where to set them?

[BigToque]

My component speakers have a frequency response of 48Hz to 25KHz. My subs have a frequency response of 37Hz to 150Hz.

Do I want to set my components HPF to be as close to 48 as possible or should I set it higher like say 60 or 100Hz?

What about the LPF for the subs... Do I want to set it as close to 150 as possible, or do I want to set it lower to something like 120 or 100Hz?

Do I want any overlap?

How do you find the best possible balance?

Generally speaking, the subs LPF is supposed to keep too much midbass from being played through the sub, and the speakers HPF is suposed to keep too much bass from being played through the speakers.


I'd start with 80hz for both, and tune from there.
You want a nice blend between the subs and speakers, so that you're not missing out on any "midbass punch", but you also don't want to overburden your speakers with too much bass, or make your subs play too high.

just do this until it sounds good

over explaining or getting into details doesn't work if you don't want to get that in depth and you'll probably be happy with those simple results

What about if I feel the tweeters on my components are putting out a wee bit too much treble. Can I adjust my amp to cut out some of the high freq stuff?

i think you can toss a resistor in the crossover for the tweeters to cut off some of the treble.. dont quote me on it though, definitely verify with a more audio-experienced person 😀😀
