Run a new power wire from the battery into the car for your constant power. Then find a fuse like the one for your windows that only works when the car in in the run or acc position and use this for your switched power: https://www.partsexpress.com/pe/showdetl.cfm?&DID=7&Partnumber=071-580

That thing is expensive and another trip to the store, how about wrapping bare wire around the side that doesnt have power in the fuse and inserting it back into the holder?

It will work that way. I would not do it in my car! The cost I guess is depending on how much you want it to be safe and professional.

If you have the acc on in your car use it. It does not carry that much power, all it has to do it provide enough juice to trigger a switch for the hu to power on. The constant power run new, but use the car wiring for the acc on.

Just go in your ignition harness grab the constant 12volt wire, fuse your new wire from it to the head unit, and do the same with the acc wire from the ignition harness.  Fuse both wires at about 20 amps assumeing your useing 14 guage wire. and SOLDER! the conections
