Subwoofer wiring

[juice]

Apologies if this has been covered before, my searching couldn't find it.

I bought one of those slim "under the seat" subwoofer units and have wired it up to the head unit and ground, no worries. However I am still looking at the best way to get the 12V power to it. The manual for the sub recommends running 8 gauge wire with 30A fuse direct to the battery but that seems a bit overkill to me. The sub is "1500 watt" but that is in fairytale numbers so I doubt it is going to require that sort of power feed.

I had a poke around looking for convenient holes in the firewall anyway, but no joy.

What is my best bet?

There is a rubber plug in the firewall on the passenger side. You dont have to remove the plug. Its rubber so its quite flexible. Poke the 8 gauge wire through there from the engine bay side and it is easily found on the other side under the glove box. Just remove the cover under the glove box (just a few clips). Then hide it under the scuff guards until the seat.

Thats my set up anyway :) Hope it helps!

If you have another amp you can connect the power cable to the power port of the amp. That's what i did with my under the seat sub.

Thanks guys. I ended up going with jaysonn341's suggestion and it works great. I figured out the rubber firewall grommet has two "spare" channels on each side of it. If you look from the engine bay side you see two rubber "fingers" next to where the main bulk of cabling passes through. If you lop the end off a finger then the channel passes all the way through to the passenger side footwell. My power cable fit through perfectly :)

I ended up running the cabling with the rest of my head unit cabling under the centre console as I had removed the centre console cover to install some other stuff anyway. Works great :)
