I bought a powered sub to go with my base '09 HU. Everything is hooked up behind the HU correctly (even talked to the Crutchfield guy about it), but there is no power to the sub. As it looks like my ground is the problem, where do you all reccomend putting the ground cable in the trunk of the xB2? And I know to scrape off any paint where I put it, I just need to know the best place to put it.

 

Run it to one of the selt bolts.

Just a question, how do you know it is your ground that is the problem? Did you test your power lines with a multimeter to make sure you have power and turn-on signals?

 

Also check the remote turn on wire. Seat bolts are okay. Scrape and sand until you hit shiny metal, then run your wire lug to the bolt. Add a dab of Loc-Tite to the bolt and torque it down. Spray paint over the bolt to cover any exposed metal.

 

Thanks guys I got it working now!

 

Curious to know, what was the problem?

 

Turns out the first Crutchfield tech guy was wrong on one of the wires, so the second guy straightened it out. The ground was ok all along.
