Question about Car Audio & Video
I just installed a new stereo and speakers in a 1966 mustang. when I turn on the stereo I hear a popping noise through the speakers any Ideas? How important is the + and - connections on the speakers and could this cause the problem?
Does this only happen when you turn the stereo on? If so, it's perfectly normal. It happens when the amplifier in your stereo powers up. It's an older car with "unshielded" wiring that isn't going to be grounded properly. Oh, and to answer your question, yes, the plus (+) and minus (-) are for positive (+) and negative (-) terminals. Make sure that red is on positive and black is on negative. Reversing the polarity (installing the wires backwards) normally won't make the system stop working but it can damage your new speakers.
You also should make sure that you've connected the stereo ground. It will probably be screwed onto the back of the stereo and if there isn't a provided green wire in the bundle coming from the car than you'll just need to find a place to attach it to the car's metal chassis.
