It depends on where you are mounting your antenna

Well I guess. But if there was a good spot to get through the firewall I'd make it work regardless of where my antenna's mounted.

It wouldn't make sense to run the cable through the firewall if your antennas are located on the roof.  If you are putting it on the edges of the hood, then ya the firewall would be my choice.

Yeah, should have mentioned I was mounting at the side of the hood. Well at least i was planning on. Kinda hard if you can't find somewhere to run your cable. God i hate wiring...

One of the problems with the firewall, is that the connectors are so large for the antenna. If you felt comfortable cutting the end off and crimping a new one on, it would be a breeze. Heck, I've got a spare end I would give ya Dan. There is an electrical boot under the glove box that has enough room to sneak a cable thru.  What i do is push a phillips screw driver thru the area between the edge of the boot and where the loom comes through.

Then just chase the cable back thru as you remove the screw driver. Might be a two person job!

Thanks for the tip!

I will try and find this boot you speak of. I don't have too much of a problem cutting the end off, could I just use a regular butt connector to re-attach it??

I wouldnt just splice together with a regular crimp because you have two connections inside.  I would take the very end of the cable off and then crimp one of these on.

here is a pic of where I routed my amp wiring thru the firewall.  It is located just below and to the right of the battery tray as u are looking at the battery.

I took me all day but I finally got the whole system up and running. Time for some mischief with the PA!

Thanks for all the help!!

Let's see some pics

I'll try and take some tomorrow.

I ended up finding a large rectangular rubber boot just below and inboard of the battery. With an exacto knife I cut a slit in it and away I went. So easy.   

I'll snap some photos of the boot and of the antenna bracket I made.
