    Hello,
    I have a 2024 Prius prime xse premium with the jbl sound system, which harness and colors did you tap into for the two front speakers ? I’m looking forward to adding a jbl bass pro 12 in the trunk and as you mentioned before the front speakers are better than the rear. Also is it easier to just buy the harness and tap into that one compared to splicing the original harness ?

    Yes :)

    What it SHOULD be and what Toyota has made it to actually be are different things.

    And this is not new to the Prius 5th Gen. It will not be changed no matter how much you complain about it. This is a deliberate choice by them that has persisted over years of some of their vehicles.

    I still think you should've tapped the front signal. While I didn't check the EQ output for it personally, when I was reading up on this issue at the start of my upgrade journey people had mentioned that it did not give the full EQ signal. Whether that means it has bass roll off (the front does not at least up to 50 vol, didn't check past that), or that it just doesn't send highs (would make sense), I don't know. But since it's been stated that it's not a full EQ signal I just skipped it due to that and its weak output.

    So if you're going back in, tap into fronts, set your crossover on your sub from 80-100hz (normally for a sub you wouldn't set above 80 but your sub has to compensate for the oem door speakers so it might be worth it to go to 100hz) and I think there's nothing else that I'd change given your current gear. Maybe wrap up the wires with some tesa tape and tuck them away but that's just if you're bored.

    Go listen to the rear door speaker.
