    I have just setup my Tacoma to be actively processed and running in three-way configuration. i have a couple newbie questions:


    1. i have removed my passive crossovers, so how do i set my crossovers for my mids. My amp is set for a HPF at around 60hz so i don't send the low-lows to the mids, but how do i cut the high frequencies so that just the tweets will deliver them. is that something i should be doing with my imprint processor? or will the mids just not play them because they "can't"?
    You can see details of everything ive done to the stereo here:

    Are you running a three way with tweeters, mids, midbass, and sub or are you considering a three way the tweeter, midbass, and sub? If it is the latter, which I assume it is, you need to set a bandpass filter for your mids. Set you high pass where you want your sub to take over and then your low where the tweeters need to come in.

    wow... crutchfield is awesome. Turns out i already have a bandpass filter! Thanks for the reply FishNTaco:

      • Tweeter/High Pass Filter: crossover from 1 kHz to 20 kHz in 1/3 octave steps with a slope of 6, 12, 18, or 24 dB/oct, additionally you can adjust the output level from -12 to 0 dB
      • Midrange/Band Pass Filter: a band pass has both high pass and low pass filters; HPF 20 to 200 Hz in 1/3 octave steps with a slope of Flat, 6, 12, 18 or 24 dB/oct; LPF from 20 Hz to 20 kHz in 1/3 octave steps with a slope of Flat, 6, 12, 18 or 24 dB/oct, additionally you can adjust the output level from -12 to 0 dB

    You're going to have to play around with it to find out where it sounds the best. It's not just a set it and forget kind of thing. An active setup takes a lot of time to set up properly.
