Oops, forgot to say it's the Nak system. That seems like alot of excess wiring to go from the headunit to the trunk and back to the fronts.
I did it like 2 days ago, its not that bad, but you'll need about 45 feet of wiring. You only have to wire from the HU to the trunk, after that its already prewired right to the speakers. Its alot of work, but soooooo worth it
pretty sure, when i upgraded mine i forgot to get that rear deck amp and my front speakers didnt work but my sub did. i beleive the sub/rear speakers amp is under the changer.
