I'm installing a Rockford Fosgate T600-4 amp and 6x9 speaker lids in my saddlebags. My question is, for those who have a similar setup, what size hole did you use for your 4GA power, 4GA ground and 16GA speaker wires?

Where is the best place to drill the hole and what did you use to cover the hole on the outside of the saddlebag after you threaded the wires through?

Any help would be appreciated and pictures would be even better.

Thanks!

 

Painters tape and used a 3/4" hole saw. Start in reverse to help keep from chipping the paint. I also found it beneficial to drill the pilot hole first and then use the hole saw.

8 gauge should be sufficient as well unless you are running the 4 gauge to a distribution block.

 

Just to give you an idea of where I ran my wires. Everything is quick disconnected. I made 2 holes to separate the power/ground from my speaker/rca wires, not sure how much was gained here since they are all zip ties together on the bag rail anyway lol.

 

4 gauge is a lil much. 8 is fine.

 

Thank you, I will use painters tape and 3/4" hole saw. What did you use to cover the hole on the outside of the saddlebag?

 

I used these bulkhead grommets thanks to Slye. I put the rubber and nut on the outside bag part and trimmed off the excess threading

 

That's a nice clean setup. Do you have any concerns with water coming through the holes if caught in the rain?

 

Use a uni bit. Less chance of chipping.
After running the wires through a rubber grommets use clear silicone to waterproof. Just a small coating.

 

Im not overly worried, but I have some rtv sealant to fill in the holes if I want. And will as often as I've switched things out I don't think I'll use the sealant just to make running wires easier when needed.
