If the amp has a small barrier strip for power and speaker terminals you can use a 4 gauge crimp connector designed for that exact purpose. Otherwise there are other options. I can't remember what type of terminals those amps use. But a friend will be over at my place in a couple days and I'll take another look at his RF.

Running the 0 gauge under the carpet is very easy. Most of the way it will be in the corner, right down the side of the car. There are a bunch of other wires already in the same area and adding a single or more 0 gauge wires should be simple.

Look at the terminals in the middle of that page.

The RF amp has straight stripped wire inputs for power and ground (no connector needed, just strip the wire and push it into the terminal). Currently I have the amp power wire running along the left side of the middle console. My speaker wires are running alone the left side of the car, and I wanted to keep them away from the amp power cable. Switching to the 0 or 2 gauge wire would require removing the seats and carpet again . I'll weigh the pros and cons and see if I have time to do this.

Thanks for the suggestions,
