UPDATE: I used my wire tracer and confirmed that the drivers door speaker wire does lead to the frunk and the drivers dash speaker does as well. However, none of those lead to the dash and connect up with the head unit. I would assume that there was an aftermarket amp in the frunk at one time that all the speakers plug into along with the big sub. But now that is gone, I assume like others have said is to buy a small basic amp and reconnect things that way and run sound out via RCA cables to the amp then to the speakers.
Sound about right?
