    As of 5/21/15 my HC sits at the dealer for Piss Poor sound quality from my 18 speaker 8.4 sound system.
    The volume level is very low compared to my other SRT units. I drive a SRT Jeep daily and it sounds light years better than the HC.
    I have had the flash done and its sounds worse plus the screen freezes up WTF!!
    I dropped it of on 5/13/15 and refuse to pick it up until its fixed.
    Last word dealer is getting intel to change head unit and amp?
    Does anyone with a Challenger HC have any solutions?
    thanks

    I have had my entire unit replaced and still can't even turn the damn radio off. Favorites do not work either.

    You just noticed this LOL! Did you do the UConnect updates and the dealer only amp flash?

    On 5/6 a TSB came out which is a dealer only flash for the HK amp. I would ask the dealership if they are aware of the TSB and if it has been applied. http://www.hellcat.org/wiki/?title=08-050-15-Flash:-Poor-Audio-Sound-Quality

    Pretty much ever body says the sound quality/volume is sub par. The Uconnect updates and this service bulletin are what is available.

    It's nice that your dealer is looking into replacing parts but unless you have bad hardware the dealer isn't going to be able to help much. The dealer can't fix bad design.

    The Uconnect updates helped a bunch of issues on my car. It's better but still sub par. I need to get the TSB flash done.

    Most of the time I've got the windows down and I listen to the mechanicals of the car but I would like my audio system to sound good too.

    Im having same problem. Need to set volume at 24 to hear it. The sound that comes out is extremely "tinny" . Definitely have some cracked speakers. Cant compare to my 2012 srt stereo. Huge disappointment. Going to dealer on Tuesday. Im so surprised that this pos system passed inspections /quality control to begin with

    My car has 138 miles on it and the left channel is cutting out periodically - its out about 20% of the time.

    The system sucks for sure.

    That TSB seems to only list Chargers and Chrysler 300's.. I wonder if the Challenger could be updated if one took it in?

    Challenger sounds like sh*t, have done updates. Only real noticeable difference is now favorites doesn't work- FCA, we have a problem!
    -I'm comparing to '14 Shaker, that system rocks.

    Good point. I missed that! Hmm... I bet it's a different amp in the Challenger but no idea.
