Do you know which part# is the original mounting bolt (for the sub but no spare)? Need to buy the right one soon. I assume its 1K0-803-899-D but wanted to confirm.

You are correct. Here's mine for confirmation:

I plan on doing this in a few days....has anyone put the Helix sub UNDER the spare? It seems to fit fine with spare sitting on raised lip of sub. My thought is if anything I would be using the spare before I have to touch the sub. I wonder about sound but know low notes travel through stuff fairly well.

The spare weighs more than the sub though, so you're putting a little more stress on the little plastic bolt by trying to hold the extra weight (which would be higher now) down.

I get your point though, but I would think you'd want the weight lower

Has anyone checked their Rabbit models to see if anything is pre-wired?

What I did with feet removal for spare tire:


Rather than just removing them I re-attached them with the screws 3" in from the outer edge. This keeps them if you ever want to set it down and will fit inside the rim of the spare. It will also help keep the sub centered on the spare. You do have to shift feet around slightly to clear speakers but it ain't rocket science. I filled the old screw holes with small 3/4" screws just because I had some.





Instead of disconnecting battery to kill power to the head unit pull the 20 amp fuse located behind coin bin by drivers knee/steering wheel. Top row 3rd from right.

I'm in the process of doing this very same on my 2019 Rabbit + installing the MIB2 + larger glass radio screen. It's going to be a long project day!

I didn't run the harness through the tire hole, reason being what if I need to use the spare? unplugging the harness from the amp isn't quick and there's always a chance you break the connector. I put some felt near the amp to let the harness wire sit ontop of the spare, thus far no issues and it does wiggle so it's not being pinched. Just FYI because I did try the 1st way but then simulated needing to remove the harness from the amp and it took a hell of a long while! Otherwise great solution and works great! Thanks to all who contributed.
