Hey just wanted to share a few thoughts on this. I unplugged the sub this morning on my 21 Iimited. Even at bass at -5 was giving me a headache…especially since my 3yo is now into Rhianna.
I tested a few different things and at the end of the day I just left it unplugged. It’s now lacking a bit of mid range bass but it does indeed sound far better with the bass setting maxed. I think the culprit is very weak 6x9s and I’m likely going to bite the bullet and replace those. It now sounds much closer to the “base” HK system in our X5. I think the 3.5s do most of the heavy lifting in these systems, did Ram just put a sub in to compensate for crappy 6x9s?
I also plugged the sub back in and removed it from the enclosure and noticed all the boom was gone. It actually sounded real good plugged in and just lying on the back floor - as soon as you stuff it in the box it booms. I think the problem overall with this system is a shi tty plastic sub box. Unfortunately there’s no room to just “leave it hanging” without rattling or screwing up the back panel. I tried stuffing the box with towels and also tried leaving it loose but the boom remained. I honestly think a good custom wood box under the seat like the gen 4 would help a lot. I’m terrible with car audio so I’m probably just going to leave it unplugged and hope to get better mid bass from upgraded 6x9s
Finally, here’s some tips for guys wanting to do a simple unplug with a couple pics as I encountered a few differences from the experiences above.
For the 21 it’s pretty easy. Find the seat back string and pull (come at it from the middle seat with the back pulled down) and remove one single grommet. Also sliding the seat forward (recline position) gives you a few extra inches to work.
Pull hard on the back lining from the C pillar as mentioned by the OP. The wire is now contained within the white harness and you need to unsnap it. Everything goes back easy. Of note see the air pressure flaps that cause some peoples trucks to boom at certain speeds.
