I would do what "Aneonrider" mentioned,but would use Adhesive-lined shrink tubing once you made the connection.Cut the shrink tube to overlap the connection at least a 1/2" on each side.Once you heat the heatshrink,the adhesive liner will start to flow around the joint.Heat this type of shrink tube with either a Heatgun or a blowtorch,and "Do Not get real close" w/ the blow torch flame if that's what you use,and use back & forth motions w/ the blow torch.
And heat all the way around the tubing to make sure the liner melts.You should see some of the liner seep out the ends of the tube.I've used either tool for the job.I used 1/0~Welding cable for my power and ground.The Insulation will take alot more heat than car audio cable insulation,that can melt with too much heat applied.Just my $.02.Good Luck and take your time. //content.invisioncic.com/y282845/emoticons/wave.gif.002382ce7d7c19757ab945cc69819de1.gif
