A DMM is a Digital Multi Meter. It's very simple to use, and if you plan to continue in this hobby its a great tool to have.
Oscope is a shortened version of oscilloscope. The DD-1 is a Distortion Detecter than Tony D'Amore and Steve Meade have just released. It detects distortion, and clipping causes distortion. So it basically detects clipping as well. I believe that is how it works.
What brand 1/0 wire? Have you tested the resistance of your ground connection?
Yes, definitely learn how to do it. It's incredibly simple.
AGM is Absorbant Glass Mat, a type of battery.
By reputable, I mean an amplifier that is proven to do rated power. Maybe reputable isn't the word I was looking for lol.

My dad has a DMM but it doesn't show the graph and all that. Just numbers and stuff haha.
How much does this so called DD-1 cost?
Um this guy that knows a lot about car auido said I have the newest 1/0 wire. Its some QA wire. He said its good s*** lol.
So what battery would you suggest?
How would I know if its the proven to do a rated power?
