I'm in the process of installing a sub-woofer amp in the trunk and have been eye-balling the best spot to run the 4-gauge power wire through the firewall to the battery. My current game plan is to remove the battery and the tray to get a better look from the engine compartment side and make some room to work.

If anyone has a recommendation (or photos) on a good spot to get through the firewall on the driver's side it would be appreciated. Thanks!

If you have an automatic. There is a rubber grommet where the clutch mechanism would be.

Found it! I saw the pre-cut in the insulation under the dash and was wondering what it's for.

I installed a round wire grommet in the larger factory grommet for a 100% leak-tight pass-through. Thank-you very much, saved me a lot of time!
