I'm planning on building a set or two of interconnects here soon for my car audio. I've been through 1 or 2 of the sites that people have put up but it never answered a question of mine. The tools, are they absolutely necessary? I understand they make it alot easier to do but what if I'm not going to make alot of cables and its really not a time critical project? In the future I'm planning on making all the cables for my home theater, but not till I upgrade my receiver and some other stuff so its not a concern right now. I plan to buy the tools then, but just wanted to know the necessity of them... Thanks in advance.
