What is turn on / turn off pop?
A lot of people have probably noticed that after installing a new piece of equipment, you will get a pop in your speakers or subwoofer when you first turn the key on, turn the key off, or sometimes both. There can be many causes of turn on/off pop including amp ground, bad amp, or the order the amp is being turned on or off.
Probably one of the things people have the most trouble with when installing multiple subs or dual voice coil subs is when it comes to wiring them to the amp. This post will explain what series and parallel wiring is, a little bit on Ohm’s law, the difference between single and dual voice coil subs, and how to wire subs to different Ohm loads.
