Further Down the Rabbit Hole We Go

If you have been following my other thread, I have been on a months-long search to find a way to kill my 2012 JGC's speed sensitive volume feature.

Today, I experienced a major leap forward in my search for information. I received a phone call back from Mitsubishi, manufacturer of the 430N RHB media center. They spoke with an engineer at Chrysler and the engineer confirmed that the programming for the speed sensitive volume control is built into the amplifier.

So, my question to anyone out there is this: has anyone either done any aftermarket work where they have circumvented the factory installed amp or replaced it altogether?

My initial plan was to connect an AllGig module to the headunit, which cuts speed info to the HU. This is all well and good, but a source told me that the amp is getting its speed signal via Can BUS wiring harness and not an analog signal from the HU. That means that no matter what I do to the HU, the amp will still modulate the sound.

So, if anyone has dealt with replacing the amp or abandoning the amp, id like to know if you encountered a Can BUS wiring harness at the amp, or was it wired directly from the HU. My suspicion tells me it's the former.

Any help/advice is appreciated.

Thanks,

Josh

If you want to do that, be prepared to remove everything head unit and amp related. Chrysler has used data driven amps for almost a decade now, and the source unit will not have a normal volume output when equipped with the amp, it will output all your stuff, but only at a set volume.

Good luck.

there should be threads here on upgrading the audio system. My durango had the audio system upgraded and two alpine amps installed so I know it can be done.

Personally, I wish my 730 had it. If it does, then I don't notice it. With windows down and sunroof open, it's hard to hear the system clearly at highway speeds without cranking the volume too high (almost max). Then it's too loud when I slow down. Granted, listening with the vehicle open to the air probably isn't intended, but I get so few nice days in the Pac NW that I like to enjoy them as much as possible while I can.

Listening to anything with windows down and moonroof open at highway speeds is near impossible :p That's a LOT of wind noise to overcome. Just for fun, you should download a dB meter app on your smart phone and see just how loud that is.

80+ with all windows open is actually very, very loud.
