    I have installed the Apline ilx-f309 in my tundra (factory JBL) and finally getting the time to sit down and dial it in. I'm pretty impressed by how much it 'woke up' the factory speakers, although I think it's possible to get it better. Does anyone have a guide or advice on tinkering around with the frequency limits that can be set for front, rear, and subs? I honestly have no idea what I'm doing when it comes to the crossovers with the factory components. Any others with this headunit care to share their settings? Thanks in advance

    yes Alpine crossovers filter when adjusted properly will wake up your system.
    Alpine used to have an app where you can load other people settings to your system and go from there. It helped me dial my system.

    Yeah I've been messing around with the app, however I'm wanting to learn a general basis on what all these numbers mean so I can set up my system the way I prefer. Also very few tundras on the user uploads through the app. And none jbl that I have seen

    it's really up to each person but I will say start with any truck settings and fine tune it to your liking. I think I started with a 2016 Tacoma and adjusted from there once I understood what each setting was doing for my kind of music.

    that's pretty much as low as you can go. High you can go up to 17.5 KHz

    you have 3 major bands: low, mids and highs . Adjust filters for the band. slope is the shape of the filter i.e frequencies low pass/high pass. flat means it won't taper, it just stays flat.

    Eq set to flat.
    You can tinker with different frequencies but the main function of the eq is for 'room correction' and that requires an "real time analyser" (RTA), or a niffty free program "Room Eq Wizard", the 20$ mic from parts express, some tutorials, and some free time.

    Crossover setting depend on the speakers, but some common arrangements:

    Subwoofer - lowpass filter, 80hz @4th order slope.
    *ported box, subsonic filter 28-30 hz.

    Mid speakers - high pass filter, 80hz to 100hz @4 order slope.

    Mid speakers (same speaker as above) low pass filter - 4k hz @4th order slope.

    Tweeters high pass filter - 4k to 6k hz @4 order slope.

    Those settings are usable as a starting point but the amount of spearkers and their t/s parameters, those setting might not be useful at all.

    Yes, you wont play below that frequency, kind of sort of. That is the frequency that the filter starts to reduce output of anything played below that number.

    The setting "slope" is how dramatic the output is reduced. Higher the number, the more it effects it.
