Help. Firewall?

I own a 2001 Honda Civic LX Coupe I recently bought a Rockford Fosgate amp to hook up to my two ten inch subs. Problem how can I get to the firewall to hook it up? Are there any grommets and I can punch through for it?

I'm not familiar with that car exactly, but there should be some grommits already there with wires running through.

You can also think about running it to the frame and out to a fender then to the battery.

Follow the wiring for things like headlights and such to see if they can lead you to a way into the cab.

I assume that you have run your wires to your firewall already. Just use the openings that are already there. Look under the dash on the drivers side and you may want to see places to put you wires through. do not make another hole unless you don’t have other choice.
