Note: if not using the Y-RCA splitter. Connect the OEM adapter to the white input on the amp.

We are sorry this took SO FREAKING long to get out to you guys. It was an extremely annoying process to get these in our hands. I will have the install video go up on Sunday, but figure about 2-3 hours for the install.

Only recommended for R1S, as stated in the link provided? Would this also apply to R1Ts?

R1T has its own product And Different recommendations but I have been using the 47Key in my truck and it's amazing.

Beta testers have been running it for months. Also no issues across all the T systems sold.

We also run our own power for the amp.

Purchased! Thank you for working on this. I'll just need to gather the courage to rip the interior side panels off 🤪

Hopefully the install video will be up tomorrow.
Maybe we should have a project day and upgrade our vehicles LOL
I'm not clear where the sub is located, mine may be extra challenging due to all the extra stuff in the door panels etc. Hopefully not, though may rule out this as a possibility.

The S has a 10" sub in the passenger side panel in the rear trunk/storage area. You can see the grill there. This kit allows an aftermarket sub and to replace the OEM one.
