Can change whatever you want, but the factory HU doesn't send much power back there. Also due to the design of these trucks and the speakers being that low, even with a new HU you will need to crank the rears in comparison to the front to get a balanced sound. I think my rears are about +3db over the front IIRC.
It sounds like you're experiencing a common issue with the rear speakers in your 2020 SR5, where they're not producing much sound at higher volumes. One potential fix could be checking the balance settings to ensure that the sound is evenly distributed between the front and rear speakers. Additionally, verifying the wiring connections and speaker integrity could help diagnose any potential issues with the rear speakers themselves. If these basic troubleshooting steps don't resolve the issue, seeking advice from a car audio specialist or consulting with fellow owners on forums might provide further insight or potential solutions tailored to your specific situation.
