IMO the factory HK system isn't worth it if you don't mind doing some minor upgrades to the Alpine system. If you plan on never touching the truck then go for the HK and just disable ANC (Either with AlfaOBD or the ANC bypass harness). The configuration in the 19+1500's is slightly different than the HD's, but I've ridden in and worked on more than enough rams to experience both in stock and slightly modified configurations. In my experience the Alpine with upgraded speakers, some basic sound deadening, doing something subwoofer wise, and disabling ANC makes them sound quite a bit better than the stock HK system. That said nothing you do to either of them is going to make them anywhere close to audiophile grade until you replace their meh amp/dsp situation that's engineered around low cost stock speakers and the loss in frequency response due to ANC.
One month update... the Alpine system in the 2024 Limited SUCKS! Sounds TERRIBLE. Everything sounds "tinny"... like I'm listening to a 1980's Chinese boom box. There is no base... no range. The factory Alpine system in my 2014 blows this thing away. I couldn't be more disappointed.
I don't have time to do a lot of work.. but this thing is so bad I'm ready to drop Sirius XM and turn it off. What can I do to make this sound similar to my old system?
Honestly, with all the crap I've had to deal with I wish I had my old truck back.
Do yourself a favor... spend the 5 grand and get the better stereo, bedliner, in-bed lighting, etc. I was STUPID for not getting that package.
This will be the last vehicle I ever order. Never again will I trust a manufacturer - they've cheapened everything.
