Looks like a great set up. I’m in the middle of figuring out what subwoofer upgrade I’m going to do right now after my BavSound Ghost kit failed again. I’ve got two loaded enclosures about to go in the rear passenger footwell. Would love to ask you a couple of questions on the route you went!

How much bass are you getting into the cabin and past the insulation? Is the backseat pass through open? How’s the rattle? Any sound deadening material installed for it?

I'm looking into doing something like this:



I'm trying to find the middle seat in Caramel to let my audio guy cut up that instead of my OEM seat. Then I can swap it back if I want.

I am getting more than enough bass. I do have the pass through open slightly. I have like a 2 inch spacer to prevent it from fully closing and thus the bass easily passes through without me having to push the subwoofer very hard.
