Where is a good ground in the trunk? It seems when I had my bazooka grounded to the trunk latch, it worked fine. That is not realistic. Anyone else have a ground idea? I don't see any more places to attach!
This is the absolute best way to do it. A nut, a bolt, a hole, and a sanded bare metal surface is what you need for a proper ground connection. Self-tapping screws will loosen up over time and cannot be relied on for holding down a ground terminal. It's easy and simple, but most certainly not the best or most reliable way to do it. I'd even add a lock washer or use a locking nut.I have basically done the same as Boats with the cars I previously owned. I would drill a hole and use a bolt. I would use a Dremel tool to sand the area and then paint over everything once it is secured to prevent rusting. The area where the spare tire is stored always seemed to work best for me.
I haven't had a chance to install my system in my Cruze yet, so I didn't look for mounting points that may already exist. If there's already a place like this to mount it to, definitely do that, but don't forget to sand off the metal surface so you make a good contact.Nooo don't drill! On the passenger side to the rear of the fender, there is a box mounted (remove trunk liner). There are grounding bolts already there. Just loosen the nut and attach your Bazooka ground. That is what I did with mine and all is good.
Can you take a picture of how you have the ground wire ran? I did the same as you. But, need to find another place to run it as it looks like the tire resting on it is having an affect with the wire..I ended up using the stud that holds my spare tire in place. It is close to the sub and the eyelet they supplied fits right over it. No drilling etc seems to work fine with the spare fastened in. Thx for all the ideas tho.
