Iphone to car speakers

[TechNova]

I don't want to run a conventional radio, gauges will occupy that spot for better legroom.
Is there a Bluetooth driver that will receive the Bluetooth signal from the phone
and send to conventionally wired speakers?
I am aware of Bluetooth speakers, have one in my shop don't want that in the car.
I want a conventional 6x9 dual mount in the package tray. It would also be cleaner to power a driver under the dash and regular speaker wires to the rear without the need for power in the rear.
And, it must pair automatically to the phone I set it up with, my shop speaker has to be manually repaired every time I go out of range.
Pre-pairing a couple phones would be a bonus feature.
