Ya when your learning about things like that it can be confusing but no worries man that's what this forum is for. Just read and learn as much as you can so you can make an informed decision on whatever type of product you buy. Read up on impedance loads, subwoofer wiring diagrams, etc or whatever else you want to learn about and also understand and know the specs of your patrticular amp so you know how much power at a certain ohm loads the amp puts out. Then you can figure out the sub wiring configuration which will best suit your desired setup.
