Need help with kicker hideaway 2021 Tacoma

Hey what’s up guys needing help on connecting the speaker outputs on my kicker hideaway do I to into my factory harness or where do I tap into any help would be appreciated thanks in advance

 

I just tapped one of the rear speakers

 

Just so you know, Toyota crippled the rear speaker output on the latest generation. To see for yourself, put the fade all the way forward, put the volume at a comfortable level, then fade back. The volume is almost nonexistent. Best to tap into the fronts for best performance. If you can’t get to the door, go behind the headunit.

 

I tapped passenger front in the kick panel from a post I saw here somewhere.

 

Definitely tap the front speakers.
