Today I finished installing a new Android based head unit (Atoto S8 Ultra) and a new sub since the original JBL sub was blown. I decided to go with the MB Quart DS1-204 sub and so far it's working great.

Here are the wiring harnesses and parts I used in case someone else is looking into using this radio (for JBL system):

- Metra 95-8210 Double DIN Installation Kit
- Metra TYTO-01 JBL Amplifier Interface Harness
- Metra Axxess ASWC-1 Universal Steering Wheel Control Interface
- Metra 70-8114 Steering Wheel Control Wire Harness with RCA

To get the steering wheel buttons to work right with the S8 model, make sure to set the wiring harness radio input setting to 22. This took me a while to figure out as the Axxess manual only mentions the settings going up to 18 only. I had to call their tech support to find out that it actually goes up to 23 now.
