    Hey everyone. So I was able to get a great deal on a 2017 Prius 2 and wanted to upgrade the sound system. I traded in my 2016 Dodge Ram 1500 Big Horn with the upgraded Alpine system in it and now I miss that awesome stereo like I lost a child... I'm a huge gadget nerd when it comes to all of the different displays I can watch when I'm driving, so I know I don't want to lose any of the functionality of the OEM head unit just to get better sound. So I have read so far there is no way to replace the head unit without losing at least some functions that the stock head unit has, but is there a way to at least upgrade the speakers and maybe the amp and get at least a little better sound quality? I'm not opposed to getting an upgraded OEM head unit from the dealership to replace the one I have if I need to.. Any advice or suggestions would be appreciated. Also a good place to even start would be the best.. Thanks in advance!

    If I did lose any oem functionality, I didn't notice. I would start with replacement speakers though. Probably the biggest bang for your buck.

    What all did you do to upgrade your sound system? Did you end up changing out your head unit?

    I changed everything. I have a JVC head unit, Audio Control amplifiers, Audiofrog mids and highs, and Massive ToroX 12" subs.

    How difficult was changing out the speakers? I’m not as concerned about the door speakers as that seems fairly straightforward. The ones in the dash seem like they will be difficult to get to.

    Issues to note with changing out the speakers (at least on a Prius Prime 2018 with non-JBL):
    1. It is difficult to run aftermarket speaker wire from the cabin to the door. Very little space.
    2. If using the factory speaker wire in the door, keep in mind that this wire is connected in parallel with the dash speakers. This means that if you disconnect the dash speaker, power will not run to the door speaker.

    Not sure where you heard about losing some functions. If you get an idatalink compatible head unit, you’ll keep the functions and get more. With most other head units, you can keep at least the basics with most used functions assuming you are getting a compatible aftermarket head unit. Something with an equalizer, crossover control is recommended. I installed a compact amp behind the head unit. My head unit has CarPlay,but not cd or dvd, do it was pretty compact which allowed to fit the amp behind. It got a bit tight with all the aftermarket harness and amp, but it all fit. I reused the same wiring (dash speaker wiring parallel with door speakers). I replaced all 6 speakers with inifinity references coaxial. The sound is much cleaner, a little brighter, and bass is punchier. I got an underseat subwoofer to add a bit more bass since the punchier bass of the speakers didn’t hit the really low tones well. The dash speaker has a really large capacitor that prevents bass from going through. I didn’t install a capacitor crossover on my new dash speakers but I do notice a tiny bit of distortion on low frequencies. The aftermarket dash speakers did come with a 270uf capacitor so I’ll be installing that this weekend.
