Ok i just re-routed my power wire under my carpet in my truck cuz it was just layin on top so i thought id clean it up before i put my new sub in. Anyways when i did this i was about 1 1/2 feet short of where i wanted to put my amp so i just took a little piece of wire i had laying around and twisted the 2 ends together and wrapped electrical tape around it. Is this safe? Or am i going to have to get new wire and re-do it?
