Good bye, account! If you don’t pay close attention in hooking up your stereo than you will be spending your bank account. First, you must be sure and disconnect your negative battery terminal. For example, lets just say you weird together two wires you knew went together, and by accident you push the positive red wire aside, and it hit the metal box that holds your radio. First you would hear crackle pop, and smell smoke, and now you need to change your fusses. Because the positive wire hit the metal box and 12 volts of electricity just went all through out your car. Second, be sure not to use black electrical tape. To explain, let’s just say you had your whole stereo hooked up-perfectly enough or so you thought. But instead of using wire connectors, you decided to use the more cost-effective method of black tape. Now at first you will have no problem, but as soon as that wire gets hot no a hot day it melts the tape, and the wire falls and hits the metal box again, than you might as well throw out your 400.00 dollar piece of metal because trashed explains your radio. Third and final safety tip involves be absolutely certain you didn’t hook up the positive and negative wires together. To elaborate, you just got a brand new stereo, and you had idea what you were doing, and you just wanted it hooked up right away. You go through there just pulling wires left and right, and you clumsily hook up positive and negative wires together. Well, you better get yourself a new car or buy about a 1,500-dollar electrical system because the positive wire has electricity running through it and the negative wire doesn’t have any power, so it will melt and start a fire.
