2002 Chevy Blazer Amp Install Through Firewall
I just purchased an amp and need to run the power line from the car
battery through the firewall to my amp. I looked under the hood and around the driver and passenger's side, but couldn't see any obvious place to pass the wire through. I pulled back the driver's side carpet a little and didn't see a firewall grommet I could use. Does anybody know the best/easiest place to pass the amp power line through the firewall on a 2002 Chevy Blazer? --Vince-- |

2002 Chevy Blazer Amp Install Through Firewall
I don't know from personal experience if there is an existing hole in the
firewall of a 2002 Chevy Blazer that the power wire can be routed through. Perhaps someone else can tell you. But in case there is no easy way, you may have to drill your own hole (which I have had to do many times myself). The trick is to find a spot, usually up high, where you can reach up underneath the dash and touch the firewall (or at least a place very close to the firewall). Then drill your hole from the engine compartment at that approximate place (you may have some insulation comming out of the hole). It's best to use rubber gromets around the metal holes you will make to protect the wire, but since the large guage power wire I am generally using (usually 4 or 2 guage) is nearly as large as the diameter of the hole itself, I sometimes just wrap the power cable up with multiple layers of electrical tape at the place it passes through the hole. This protects the wire just fine and usually ensures a nice tight fit as well. Sometimes the firewalls are two layers of metal with insulation in between. This is OK as long as you drill the hole nice and straight through both sheets of metal and then insert stiff cable (anything thicker than 8 gauge is usually pretty stiff) through both sheets. It really isn't that difficult to do if you cannot locate an existing hole. Good luck, MOSFET "v1nce" wrote in message oups.com...

Luckily, I was able to follow the antenna wire down and use that
existing hole. Thanks for the info. |
