Are you using an adapter or has the original harness from the Jeep been cut?
If you are using a universal adapter you just need to switch the blue and blue/white wires from the Alpine head unit. On some harnesses they use a solid blue wire for the aux power so it's easy to connect the wrong wire.

Find the blue/ white wire coming from the Alpine. Connect it to the blue wire of the harness.
The solid blue wire from the Alpine should not be connected to anything.
 
There should be 2 blue wires. 1 is the power antenna wire, the other is the amplifier turn on wire. I haven't seen a head unit in the last 20 years that didn't have the amplifier turn on wire, but I have seen many that don't have a power antenna wire. As mentioned above, usually one is solid blue, and the other is blue with white. The way they work is the antenna wire will only put out power when the AM or FM source is selected, any other source and it will shut off. The power turn on wire will power up when you switch the head unit on and should put out power until you turn off the head unit, or turn off the key.

If for some reason you cannot find the amplifier turn on wire, or your head unit doesn't have one, the red wire on the radio harness is your switched accessory wire and the yellow has power at all times.

I had the exact same issue with a Kenwood head units. Amp and sub worked fine with FM stereo. When I switched to bluetooth streaming no amp or sub.

The solution was in the settings. I had to call Kenwood. If you can't find anything on the internet I suggest calling Alpine Tech Support.

Blue is antenna power. Blue with white is amplifier turn on. Page 44 of the pdf I attached is the wiring diagram for your headunit.
