This video is actually correct. I go to The Los Angeles Recording School
and I am majoring in audio engineering. In ALL electronic devices, the
crossover point is the point at which the signal level goes down -3dB. The
reason for this is because two signals playing the same frequency at -3dB
will end up equaling exactly 0dB. In actuality, setting the LPF and the HPF
at BOTH 60hz means that both signals at 60Hz will each be playing at -3dB
and -3dB, yielding 0dB total at the same exact crossover point. DO NOT. I
repeat, DO NOT listen to those websites that tell you to set the LPF to
50Hz, and the HPF to 100Hz because it will supposedly cause boominess at
the crossover point. All you will end up with is holes in your system's
overall frequency response. DON'T BE IGNORANT. You can install car audio
for 50 years, but still never went to school to learn audio engineering,
then you will be giving the world misinformation because you think the
crossover on electronics means the last frequency at which the signal plays
at 0dB. YOU WILL BE SORRY.
I have 2 4000 watt amps i believe its called 4 way but sometimes when im
listening to music my sub doesnt boom on every beat thats it supposed to
which control on the amp would fix the problem? and im not to far from your
location about 15 min
say if you only have your sub woofers hooked up to a amp which has the
cross over adjustment, how would you know what frequency your stock car
speaker's leave off on, so you can adjust your subs to pick up on?
Good call. Crossovers are not perfect and their actual crossover frequency
is at .707 of the full voltage. Crossing the sub a bit high and the
speakers a bit low will reduce the sag at that frequency.
plug in a the AUX cable and play some frequencies via a tone generator and
go from 50Hrtz to below and u will no at what frequency your stock speakers
cut of at
