Challenger SRT Hellcat
Lucky you challenger guys didn't have to buy this as an option, it sucks the big time and Dodge should refund every Charger owner that had to pay for this POS..........
No it's NOT! To have the HK system it actually costs 2k more!!! A fully loaded Charger is 5k more than a Fully loaded Challenger. The HK systen is part of that Extra 5k.2K is the same whether it is built in to the price or paid extra for it as an option.
I believe it is/was a phase issue. It is easier to get the amp firmware updated if you have a Charger HC, but it may be worth a shot for the Challengers since there is not currently a TSB available for them.I wonder if its just a speaker phase issue. That would make the subs cancel each other out. Pulling one out and disconnecting it would prove it pretty easily.
