This is how I installed my Kicker amp under the steering column of my 2005 Wrangler X. I used an 8 gauge wiring kit and a 2-ohm DVC Kicker sub wired in parallel for 1 ohm for 400 RMS into the sub.
I created a mount using a cutting board. I trimmed it to size and drilled the mounting holes for the amp. I also drilled a hole in the center of the cutting board to mount it to an existing hole in the steering column.
I then screwed in the amp onto the cutting board using little nylon spacers so it would clear the bolt.
I zip-tied the long RCA cables, which I couldn't cut directly to length, to the steering column.
I mounted the fuse onto an existing bracket right next to the battery. I found a #8 bolt fits perfectly into the existing bracket.
To go through the firewall I used an existing hole normally used for the automatic transmission. I have a manual so it is just a plugged up hole in the firewall. I drilled a hole in the plug for the cable. A replacement part can be bought for about $8; part #2424864.
Here is the same plug (now a grommet) from the inside.
And that's it! The amp is grounded to an existing bolt on the right side of the driver's side floorboard; next to the center console. Here is a YouTube video:
