i have my crossover for my sub set at 125 low pass and then for the fronts i have it set at 125 high pass, and i was wondering if 125 low pass is to high for a sub?

I like mine at 80... anything under that and you can really tell that the sound is coming from the back of the car.

how can i tell what my sub is crossovered at if there are no indicator marks or anything by the crossover knob on my amp?

I've never had mine set above 50hz.

The frequency doesn't matter, only the effect it has on the sound //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Honestly, don't worry about the specific frequency.

i have mine set at 35 hertz

well the reason i have it so high is because on my h/u the lowest the HPF for the front was 125 so i wanted to have a like flow from the midbass to sub bass

well ive got my sound setup which sounds good to me. just curious to know if theres a way i can find out using test tones or something. correct me if im wrong but if my LPF is set at 80 (24db/octave) does that mean 80hz test tones should be 0 db and 160hz should be -24 db??

Technically the crossover point is the point at which the signal is -3db down.
