The dealer refused to do the enhancement even though I printed out the update details from FCA website, what is the Ram direct phone number I can contact hopefully they can helpSo after much more effort than I thought it would require, I finally got my dealer to update my amplifier. Ended up having to contact RAM directly and let me tell you, they were an incredible help. Night and day difference in volume and clarity at higher volume levels, had to turn the sub down a little because its pretty overpowering, now my truck is perfect.
