Hey everyone, I recently purchased a 2019 Peterbilt 389. The truck has the SmartNav head unit installed. I'm looking to upgrade the sound system in the truck and I'm curious as if anyone has ran an aftermarket amplifier and subwoofer in their truck with the smartnav installed. Obviously I could pull this unit out and replace with an aftermarket radio but I really like the OEM look and functionality of it. My question, is there RCA's behind the radio to run for a subwoofer, or do I have to use line out converters and go off of speakers? Any help would be greatly appreciated.
Also, I would normally take a Sunday night and pull the dash to find out myself but the truck is currently at the body shop getting some "extra goodies" paint matched and installed and won't have the truck back for a week or so.
Thanks again!!
