    Setting up the DNX 8120 in a double cab 2009 taco, with stock speakers. The truck had the non-JBL stereo if this matters.

    The Head unit permits the setting of a cross over for the front speakers. I set the size (there is no 6x9, so I will guess on a size), and a CROSSOVER frequency.

    At what frequency should I set the crossover? I assume this is depended on the Frequency response of the tweeters, but, I have never done this before.

    thanks

    the best answer is se it to your ear. the best way to do this is to play somthing with a lot of bass, like rap or hip hop you want to crank it up pretty good and while your listening to it listen for distortion from the speakers they will sound like your overpowering them.
    if you move the xover higher you will eliminate some of the low bass frequencies. choose a 12 db / octive slope that HU goes all the way to 24 db/ oct move the crossover frequency from the lowest setitng to the highest setting untill the distortion goes away. then set the xover to 18 db / oct and back the xover down 1 setting. it should get you close.
    your objective here is to retain as much bass as possible without the speakers getting distorted. i would guess without an amp you can get away with about 60-80 hz with an amp a little higher than that.
    i have the same head unit as you.

    thanks, will try this. I was playing with it with music, but your procedure is much more defined, than "does that sound better to you?"....

    Appreciate the help.
