2020 ram classic subwoofer install

[cooperdavid]

Hey there, I traded in my 2016 big horn with alpine stereo and the factory subwoofer and got a 2020 ram classic warlock. I scooped the factory sub from the big horn to put into the new classic and after some digging around I've found the correct wiring harness under the floor for me to plug it in. Only problem is after plugging it in I have no power to the sub.... this new truck never came with a sub in the first place but had the wiring for it so I'm wondering if there's a fuse or something or some means of activating that plug so that my subwoofer gets power. Any and all help would be greatly appreciated!

If the factory amp is there you will need the dealer or use alfaobd to turn it on in the bcm/stereo and then it should work.

Your new truck doesn't have the amplifier to run the sub. Would be cheaper to go aftermarket. If I remember correctly, the factory amplified system has a different radio (or program to run it). You would need to replace that (or get your radio programmed) , find an amp, hope the wiring is the present. A lot of money and hoops to jump through for the mediocre sound you will get from that sub.
