The Durango has the Infinity audio option - it should be fun! The OEM HU has all but died.
It looks like I'm going to go with the PAC audio interface to try and keep as close to a 1 : 1 ratio on the HU to amp output levels. I'm going to add a TT-CC17 backup camera and leave it at that for now: replacement speakers are next, but I have to keep feeding my reloading habit and there are some sweet match grade 55gr spitzer hp's that I really want to build up a load for!
I'm going to obsess over the interconnect - but that's nothing new.
Mediocrity is so common, so forgiven.
