I just noticed the place that installed my speakers and sub drilled through the firewall to run the power cable. However they did not use a firewall grommet. My question is, will the 4 gauge cable insulation be cut overtime from rubbing against bare metal? Or is the insulation thick enough whereby I do not have to be concerned.

 

I would be concerned. The bare metal will likely eat through the insulation with enough time. I would make them fix it.

 

Cehome,

Thats why I installed my own sh$t. Its not about the money, but I don't trust most of the installers.

The installer cut a big a$$ hole in my brother's land cruiser and it caused water leakeage.

Yeah, I usually do it myself, but did not have the patience to pull and reinstall the panels in the Z. Especially the rear. This place is pretty reputable. I was rather surprised when I saw it.

 

I'd take it back and demand that they do it right. If that shorts out ....

 

Yeah, I haven't done mine but it looks as if there is plenty of room in the existing area to run the wire through.

 

there are two easy places to run the wire, seems like the shop didnt take the time to look for them...
