this plug solution to connect to factory speaker bundle
used near the factory amp
PAC APH-TY04
https://pac-audio.com/products/aph-ty04

I know the factory amp will have to stay "alive" so the factory stereo doesn't freak.. but I think I can disconnect the speakers? Confirm?

some speed wire (10ft?) sourced at a local stereo shop and crimps to get to amplifier under seat

+
TacoTune bracket? (don't want to go through carpet) (any alternatives?) +
