Splicing 4 Gauge Wire?
I am planning on getting my new amp in on probably Monday, and I realized that my power cable is probably not going to reach to the position it needs to be in on the new amp. I have 3 or 4 feet of power cable left over from the original install, so I was wondering, what's the best way to splice 4 gauge wire? I am inclined to just twist it together and wrap in electrical tape, but that'd look kinda crappy and probably wouldn't be that safe. So what's another way?
I have a basic soldering iron, but I doubt it could handle that sized job correctly.
