I have a '15 2500 CC with the 8.4AN Alpine premium sound system. Since I have been in the audio industry for over 35+ years, i know what to listen for and I felt the dash speakers were muddy sounding and the bass was tubby and not very tight sounding. Thus, I did lots and lots of research trying to find a smooth balance of sound. I also wanted to keep the dash speakers at the same efficiency as the OEM speakers so they would balance out with the remaining OEM speakers. So here is what I upgraded to:
Dash speakers: I installed Infinity Reference X REF-3002cfx. They were a direct drop in / plug and play install using Metra 71-039C adaptors. They are much more detailed sounding and have more "sparkle" than the OEM speakers. Makes for a nice image.
Subwoofer: It was tough to find an 8" dual 2 ohm subwoofer with a shallow enough mounting depth for the factory under rear seat enclosure. The Pioneer TS-SW2002D2 fits perfect - even the holes line up. Make sure you use the gasket that comes with the woofer. Also, PROPERLY plug the hole in the bottom of the enclosure where the screw that went into the back of the factory woofer. (You'll see what I mean when you take it apart) It is 100% plug and play using a Metra 72-6514 adapter.
Definitely a cleaner tighter, more accurate bass. It "may" be a tad louder but it is much less muddy and you really 'feel' it when it hits.
The system sounds pretty good with these upgrades. I am pleased with it. Hope this info helps some of you.
