Hertz Setting

I have my sub amp at 65 and my high pass filter at 100..does that mean im not getting anything between 65 and 100? what is 65 to 100.. is it mostly mid bass? thanks

it doesnt mean you arent getting anything between there it depends on the slope of the crossovers. and 65-100 is at the high end of sub bass,

thanks bro..anyone else the amps are rockford T2500bd and T600-4

Ok so here is how u can break it down.

Bass 20-80 Hz

Midbass 80-200 Hz

Midrange 200-2,000 Hz

Highs 2,000- Up Hz

This is not written in stone just a rough idea of the crossover points.

Set them both at 80 and go from there.

T600-4 has 24dB/oct crossovers

what speakers are you running? you want your high pass filter coordinated with the frequency response of the speakers you are using.

don't separate the crossover points by more than 10Hz with steep crossovers.

Yes, that

Need to be careful that the mids will play down to 80hz, plus if the crossover points overlap you can get a bump in your response curve at those frequencies, cause both the sub and mids are playing them.

Correct. But tuning by ear is always better than tuning by what works on paper. 80hz is a good starting point, then you shift them around until you find a sweet spot for your setup.

Right, cause you cant alway trust that the crossover markings on the amp are correct

24 db oct crossover what does that mean?..speakers are t1 6.5 components

The loudness of the speakers is reduced by 24 decibels for every octave below the crossover frequency. So if it's set at 80hz, the normal response curve will be 24db down at 40hz, 48db at 20hz etc. I personally use a 63hz at 18db/oct slope for my sub and 80hz at 24db/oct on my mids.

The steeper the slope the less overlap.
