what do you guys set your low pass crossover on your amp at? I have mine at 100 Hz but my so friend thinks that a bit high and should be at 80 Hz instead. any input?

i agree 80hz seems to be a good spot, but there is nothing wrong with using 100hz.

I like my front & rears at 80Hz, subwoofer at 125Hz (12dB/octave slope).
My Pioneer amps have passive crossovers builtin that are fixed at 80Hz, 12dB/octave (though I use the active crossover in my Alpine H/U instead)

Try it and see how it sounds to you. I actually switch it back and forth from my HU. I change the sub LPF from 100 to 80 and back, and the HPF on the fronts vise-versa. With some of the bass heavy music, you will get tighter hits with a lower LPF setting, cuz the sub can concentrate more on those hits.

i actually did try that this morning. with it set at 80 and some bassy songs, the subs hit a wee bit harder. at 100 it helps out with the higher bass. think i'll keep it at 80

thanks for the replies!

80 is good.

80hz is pretty standard in amps with a non-adjustable low-pass crossover.

The important question is what size/how many subs are you using? 80 is pretty standard, 50-60 is Very safe. But all of this depends on what you have.

two fosgate HEs 10s in a sealed box with a 400s amp pushing it.

I would say 80 then.
