2015 How To: Run Power Through Firewall

[QuarterSwede]

I just received a sub (the excellent 10” Pioneer TS-SWX2502) and amp (amazingly small 1600w mono Pioneer GM-D8601 amp) for Christmas and went to run power through the firewall of my 2015 (automatic/no clutch) and could not locate a grommet that wasn’t in use.

 

I read a lot of threads talking about where there is a 2” one but no one had pictures and I couldn’t locate it myself. After an hour I found it by accident. It’s just to the left of the brake booster and hidden under the rubber mat. Its right underneath the protruding rubber square. This rubber square pulls away and off to reveal a massive 2.5” grommet. From there it’s trivial to wire it to the the posts (near the drivers shock tower).

 

You used to be able to get through the drivers door grommet but that no longer exists on the 2015 (you should avoid possible pinch points anyway). It seems that as Dodge is refining the Journey’s design they’re making it more difficult to install aftermarket accessories. Why hide the grommet at all? It serves as a fireblock but once it’s permanently removed that is no longer the case so why have it there?

 

Anyway, I thought I’d post this to help anyone else installing aftermarket power for an audio system.

Did you hook up a sub? If so what were the wire colours when hooking it up? That’s if you were using stock radio?
