Hi! Tomorrow I am going to be running the power wire for my battery to my new amp. Instead of running the wire through my firewall, I was looking at running it through my fuse box. There are wires running from the engine compartment into the fuse box. I was going to run the wire for my amp with that then simply drill a hole in the bottom of the fuse box where I can then easily pull it down from under the dashboard and run it under the carpets to the trunk. Before I do this, I want to make sure it is safe to the wire through the fuse box. No, I am not hooking the wire to the fuse box, just running it through it. Thanks!

 

Why not just use the firewall passthru?
there is one on each side of the firewall
I wouldnt compromise the fusebox, for an amp wire. thats the last thing you need is moisture to get into it and corrode those connections...

 

I ran wiring for my gauges and fog lights through the fuse box. But...I routed them through the existing wire conduit (the hard plastic one on the drivers side fender) and then down through the fuse box.

 

Yeah if you were going to use the fusebox access id do that but I wouldnt drill any holes

 

I agree 100% on that. If you take the fuse box cover off with the torx screws, then unscrew the panel that the fuses mount on, it's relatively easy to slide a few smaller gauge wires down through there. I went that route because I hate seeing visible wires, even if they're encased in flex loom.
