Default Running Battery Wire to Subwoofer

In my 00' Subaru Legacy im trying to run the battery wire through the firewall to my Infinity Subwoofer in the trunk. The problem is there are no grommets to run it through. I drilled a hole into the firewall and fed about 3ft of wire into it and it went no where.

Anyone know where/what to run the battery wire through?

Thanks

-Chris

YOU DID WHAT NOW?!

Man....

The grommet is reachable on the drivers side of the car, about 8" down on the firewall between the airfilter and the strut mount.

It's covered by a piece of rubber that pulls out. feed wire in and it comes out above the gas pedal

Whoever gave you a drill should be shot.

mmmm drill bits, make sure you lick it when your done. I heard somewhere that it grows hair on your chest.

Make sure that you run the signal wires (RCA's) at least 1ft to 2ft away from the power wire to keep from getting interference or distortion. lots of RCA's for subs are shielded but the freebee ones that come with powered subs are not at all.

From inside, if you pull the floor mat, then lift the top of the carpet it will be right there. There may even be a cut-out in the carpet padding to help access it…

I can’t believe you drilled from the within the engine bay not knowing what was behind. You probably punctured some portion of your HVAC system which stretches across the entire FW on the inside. Or even luckier you didn’t hit the bulkhead harness which is right there too…

PS: Use a metal coat-hanger to investigate where how each hole passes through the FW next time...

When I've done stereo installs into BE/BH Cars, I've always used the grommet to the left of the brake pedal. On the other side of the firewall, it outputs right below the brake booster. It's always worked great for me. See pic below. You'll have to remove a precut section of the sound deadening material, and then push the grommet out. I always put the grommet in backwords because I could never fit my hand between the top of the frame rail and the bottom of hte booster to put the grommet back on. At least you can get right at it from inside the car. Just cut a slit in the center of the grommet and run your cable through that. You don't want to leave the grommet out and then end up with road grime all over the inside of your car (or have the wire rub on the firewall and then short out which could possibly start something on fire if you don't have a fuse or circuit breaker)

How do you guys run the cables from the firewall to the trunk? I'd assume you tuck them under the center console panels (where the plastic panels meet the carpet), then under the carpet in front of the rear seat and then under the rear seat itself and into the trunk? That's kind of how I ran my XM antenna cable anyways, is there an easier route?

It depends on the size of the cable. What I usually do is run the RCA's down the right side of the car, and the power wire down the left side. I believe there was enough room along the side, under the carpet for 4ga wire and still not be able to tell it was there. I was always taught to keep the power as far away from the RCA's as possible, so that's why I run them on opposite sides of the car. I've never had a problem with interference that way, except for in a 1986 GL-10 Turbo that, for some reason no matter what I did I still got the alternator whine.

I'm not going for trunk rattling, so it'd probably just be some 8ga power cable. Down the side would probably be easier, don't know why I didn't think of tucking under those side moulding things.

No, the drillbit needs to look like this:
