Im looking to see if anyone knows where to put a wire through the firewall on any of these cars (S/V/C70) to power an amp?

 

I should know. I had a system on my 850 and it would be similar in the s/v/c70 models.

There is a firewall pass through on the drivers side. You might try using that.

 

Excellent, Thanx Rob.

 

No problem. I don't know how big the wires your trying to pass through are or for that matter how many wires. So the pass through may or may not be big enough.

I think however that you can get more wires through where all the other wires come through at as well. Not sure 100% but I think you can pass some more through it.

 

What I did was run the power wire along the drivers side inner fender and through car by the hood release; just drilled a hole. But make sure you make a clean drill otherwise you'll need put some silicon on the hole so it doesn't puncture your wire. Good luck. I couldn't find the passthrough on mine.

 

the 70 series has a pass through on the drivers side. Some have a fuse box there, in the dash (the part that faces the door). (If you dont have a fuse box there, as my c70 doesnt, you have to remove the dash to access it.) There are several holes filled with plugs right there. You can feed em through that then further up in the door joint there is a big plug you can pull out to help feed your wires through.
