Better sound!

2020 tundra non jbl jl audio speakers in dash helped some will the new alpine head unit f-509 improve the jl dash speakers and door speakers sound quality a little from my understanding the door speakers are powered buy amp under passenger seat n the dash r powered by headunit what happened to tech12v website?

 

Yes the door speakers are powered by the amp. The dash is powered directly from the head unit.

So if I put a alpine head unit in it will improve sound out of dash speaker? Also do I need to run a new backup camera and mic I also have Wi-Fi in my truck will I lose that sry for dumb questions my last vehicle was a 04 so things have changed a ton I missed that best buy sale unfortunately

 

You sound like you're about a tech savy as me LOL. I think I'm just going to take the unit I bought in to an audio store and them what I want and to make it happen.

 

Your Alpine backup camera will work with the OEM backup camera with the proper adapter, if needed.
You'll need to run the Alpine mic for Bluetooth, but that's pretty easy.

You'll also need a steering wheel control interface, most of us use Maestro RR with the proper Toyota adapters.
iDatalink Maestro RR Interface Module Connect a new stereo and retain the steering wheel audio controls and factory amps in select vehicles at Crutchfield

It might improve the sound out of the dash.
Some things to keep in mind:
The front door speakers are woofers - low and mid signals sent from the under seat amp.
As @Tundra234 stated, the 3 dash speakers are powered off the HU run as mids and tweeters and will be powered off your Alpine HU.
