Thank you for the diy. The pics are awesome. cant wait for a better weather in nj to do my install.

 

i ran my amp wire thru that bar on the drivers seat worked out great

 

made it easy!

 

going to give this a shot with 0...guess ill drill if need be

 

Glad I found this write up. Looked pretty difficult to get to the firewall to drill a hole or find access from under the hood. Thanks!

 

good write up

nice diy theres like nowhere to go thru the firewall..

 

i took an alternative route

 

What if your fuse is not removable from your power wire???? can you run it through the opposite way???

 

07 Civic Si

Sorry guys if I post this incorrectly, much less answering WAY late. I've been looking for a solution to this problems for many moon now and finally found a nice way to run the wire. The previous posts showing the wire fishing won't work on some Si's as we have a double firewall and the hole goes to no where.

What I have found is on the drivers side, under the boot going into the door there is a Grommet directly beneath it. Pop it out, run the wire from the battery through the fender, through the grommet, into the car, the hole comes out above the Fuse box, run however you want.

Here is a link to my Flikr Account for picture showing how I did this. This method is much less intrusive, no chance of messing your main wires coming into the vehicle from the engine bay.

Hope this helps a bunch of people!

Made running the power wire to my trunk so much easier

 

Thank god for this thread cuz I wasn't looking to spend the money on labor for some one else to do it for me plus it gave me the experience I needed to say I can now do it and well came out perfect, also if anyone had problems with the remote wire for the amp and where to get a good on/off signal I ended up using the radio fuse I think its number 3 but it took some digging around to find a solution seemed like everyone was doing it with the antenna wire behind the back seats and I didn't feel like going that route...

 

It was a pain to pull power wire up through the fender but I got it done and it came out good. Nice diy

 

Haha, good comment. I always try to tell people they don't need a capacitor.

 

Can someone please go into more detail regarding the remote wire, where is radio fuse 3 and whats the best way to hook up a wire to a fuse.

 

I'm gonna try running my 0 gauge wire like this..

 

This post was very helpful. Now I just need to find another set of speakers for my rear, and another amp. If Anyone has an amp that can put out around 1000 watts rms at 2 ohms inbox me!!!

 

Useful post thanks!

 

This really helped me run my wires!! Thanks so much!

 

Thank you!

This is the way I ran my 4ga wire, A 0/1 should be able to do the same except where I went through the plastic in the engine compartment, you might have to drill,

Step 1,

Open engine compartment and remove side trim on the driverside.

Step 2

Under the driverside dash on the side of the car is a plug, pull out the plug and run your wire through it into the sealed fender of your car, push as much wire through as you can untill you can reach it from the engine compartment, you may need a hanger or grab tool to get the wire. Make sure you cut a hole in the plug and run the wire through it (use a grommet if your wiring kit had one) then replace the plug, nothing worse than a draft.

Step 3

Remove clip over your trunk lock, and remove the panels, be carful of the center pillar, inside it is the airbag sensor(not that you could set it off but if you damage it it might not work when you want it) and remove your rear panels, now you can either pull the seat out or just push the wire through the space into the trunk.

there is a space to run the wire when this is removed,

And voila Power to the trunk, with no drilling, or altering of any metal or material in your car except the plug.

This is what you get after all the work lol.

I hope this helps, if any of the pics need to be better just ask I'll go out and take some more with panels off etc.

I hope this post isn't too long. sorry if it is

I had this posted Before and people keep askin about it so I figured I'd start a new thread with just this post, If the moderators want to add it to the DIY go to it:wave:

I had been racking my brain for so long trying to figure out how to route my 4 gauge power wire. This had to be one of the most simple routes I have ever done now.

Thanks again friend!:dance::woowoo::dance:

 

Good write up! Will use this in the future.

 

Can anybody tell me how much wire they needed? I'm buying an amp install kit on Crutchfield.

 

about 20' should be good if I remember correctly but what comes with most kits works find @jlrpena

 

I did 3 x 1/0 power wires in my 07 si.

 

Nice

I was able to do this easier by removing the fender. The grommet's other end is behind metal.
