Where and how to tap into audio for a subwoofer?

[kas_lar]

Hi everyone.

Long story short:

I’ve got an Hansshow subwoofer with a broken harness. The subwoofer is working fine but the harness has some of the rear speakers was reversed, some wires were broken and the DSP box wasn’t working correctly. I pulled it out and was much happier without the Version B upgrade The car is a 2020 SR+ with factory speakers and rear speakers.


Last weeke I’ve installed a regular DIY Hansshow harness and everything is working. All the speakers are activated but I still need a little bit more bass.
Now I need a place to tap into to get a signal for the sub. This would be a Frankstein Hansshow setup.


Is this possible with the DIY harness and a homemade harness to the Hansshow subwoofer?

I know this is an older post but I see you have no answers. I have a 2019 SR plus that I bought my sister and I’m wanting to upgrade the audio before I send her the car. I ordered that kit as well. Not sure of mine comes with DSP or not, but I’m trying to find out where to tab to add the subwoofer. If you ever figure this out, please update thank you.

This is a step by step walkthrough of the wiring and general connection overview. This and the video above helps tie things together. Even though it’s for a RHD, the wiring is the same.
