Default Cant get through firewall with power wire!

Hi,

I recently bought a 1996 Honda Civic 1.5i LS 3dr (vtec) and I am trying to fit an amplifier. I have routed the rca cables and remote turn on wire to the boot but am having trouble finding a way to get the power cable through the firewall! I found a large rubber plug blocking a hole to the bottom left of the battery but behind it appears to be a lot of white cotton wool type material and solid metal behind that!! Anyone done an install on one of these cars and know where to put the wire through?
Any photos would be a great help.

Thanks in advance,
Kev.

You might be able to get it through the fresh air vent. The place where air is drawn in by the AC/Heater fan. There is a filter screen which you would have to push the wire through but a small hole in there shouldn't be a problem. At least it never has been for me. You just have to put the wire through in such a way that it doesn't block the systems ability to select between fresh and recycled air.

Just a suggestion. Attempt at your own risk.

If i'm not mistaken, i think i went through the same hole my clutch cable goes in, but not sure. I'd have to go look. Just went to look. Actually, i ran mine through the hole right up under where the clutch cable goes through. You'll need a razor to poke a hole in the rubber thing to push it through.

Use the hole you found behind the rubber plug you can use the rubber plug as a grommet, just poke a hole through it. The material you found behind the rubber plug is insulation/sound deadening material. Behind that may even be some heavy cardboard type material... just poke a wire coat hanger through it.

The only pic I have is of the rubber plug, you already know where that is.

Good luck,

JD

Thanks guys. I'll keep poking at that hole!! Hopefully something will go through!! All the posts i've read say to use it so it must go through somehow! If you used that hole, did you do it without taking the battery out? Also should I be looking to be pushing straight through or at an angle? (which way if it is at an angle!)

Kev,

Yes, I've used that spot on 3 different Hondas I've owned... an '87 Accord, a '97 Civic, and my '99 Integra. I have never found it necessary to remove the battery. When pushing through there, I'm pretty sure I did it with a screwdriver, then fed a wire coat hanger through the hole I made. I had to angle down toward the floor a bit.

Once I could see the coat hanger from the inside of the car, I then made a little hook on the end of the coat hanger, ran the wire through the hook and taped it to the hanger. You can then pull the hanger on through the hole and the wire should follow it through. If you meet any resistance, be gentle... you don't want to yank the wire off the hanger until it's through.

try pulling back the carpet and removing some of the sound deadening material.

on my 94 accord, I poked a hole through the rubber gromet over the brake pedal. Pretty easy. On a friends Integra, they used the gromet behind the glovebox, but I've searched and searched on my accord, and find the driver side one easier.
