!Audio help! Subwoofer Installation for my Civic 8th gen.

[wilzee]

I'm thinking about Installing a Subwoofer into my Civic 8th gen. I'm just wondering if anyone has installed a sub on a 8th gen and knows where's the best place to feed the power cable through the firewall? thanks for your help. :thumbsup:

not sure about on an 8th gen but i've allways run through on the pasengers side under the carpet you don't want it behind your pedals get under your car if you can and look at the engine side of the fire wall as you need to keep it low in the interior side! please use thick power cabel 4 awg and up i put a sub in my work van and didn't want to spend more then i had to so i ran wires in a normal extension lead. if it can carry 240v it can carry 12v right?... Wrong it melted and i'm lucky i didn't shock myself touching my van :p

i started my audio install today, pretty slow progress but getting there eventually. found the hole shown in the pic above, fed the power cable through, but now i have 2 problems:

1) how do i get a grommet in that hole? there's too much padding around the hole to get enough working space.

2) how do i get the cable from there up to the battery?

[serpo]

use screw driver to widen hole bend more and more at the metal, and to get cable to get to battery PULL! lol take photo of place where u put the hole and I can tell you from there if ya want

the hole itself is big enough :) (can almost stick my thumb through it) it's just getting the damn grommet in there that's the problem.

pulling the cable through was what i tried first, except i had no way of actually reaching the power cable (the hole i used was right behind the engine.)

any other 06 civic owners have any tips?

[serpo]

lol whyd you put it behinde engine? how stupid you will melt the cable lol I put myn on passenger side, there should be hole there or make one and make sure you dont hit anythin lol

my engine is R18, so that might explain how can I get the cable from there to the battery.. you can see it clearly in the engine bay.. however, if you jack the car.. you should be able to get the cable from beneath..
and.. I don't use any grommet.. no more space around.. can't be bothered..

ahh that's true, the 1.8 would have more room to work than the 2.0... forgot about that.

not too enthusiastic about getting under the car with it only being held up with the jack... if i do have to resort to that i'll go and borrow some ramps from a mate, but i'll try again tonight and see how i go

finally got the power cable through :) managed it by dangling some ribbon out the hole, then manoeuvring a 'rearranged' wire clothes hanger behind the pipes in the engine bay to where the ribbon was... had some double-stick tape on the end of the wire hanger so caught the ribbon with that, pulled the ribbon through and then used the ribbon to pull the power cable through. now the power cable is easily zip-tied to the existing wire looms there... just gotta wait until i buy some loom for the power cable itself before i affix it.

tried to get the grommet in before that but ended up dropping it somewhere in the engine bay... so i improvised by wrapping a small section of the power cable in ensolite (3mm fireproof closed cell foam) and pushing that through. actually better than a grommet because it's easier to install/uninstall, and also waterproof+fireproof. and obviously it'll stop the power cable getting eaten away by the firewall, especially cos it's quite a sharp angle.

ac03n: do you have any pics of your engine bay firewall power cable routing? also, any idea where to put the amp turn-on lead? :) (using the stock hu)

[serpo]

ye man rund it down same side as your power cable and put it to the back of your Deck (cd player) should be Blue wire on cd player attach to that
