So I've been saving up some money to get a nice sound system in my car but a big problem came up with me while reading how to wire this stuff I know how to do all the wiring and stuff but I've heard that if you disconnect your battery you can lose all your settings including your head unit setting and you would need a code to get it to work again...so is there any way to not disconnect the battery while wiring would it do any harm if I were to not disconnect it ?
