Various Speaker and Questions! Tell me if I got this right..

[KeithPuetz]

Okay, I have some various questions about hooking up a Nintendo speaker from my Donkey Kong cabinet to my amp.


So I bought this AMP system. Turns out there was a defect. Some of the metal on the button came off. It looks ugly, it's kind of depressing I want to return it.


I can't seem to figure out how to get this damn thing to work.

I have a bunch of metal plugs with a hole in it, it looks like they are supposed to be grounded. So I just ground those right? There is a bunch of them. I imagine I ground them.
Right?

Than there is a plug like this.

I guess that's to give it power? Right? I just plug that into my PC?

Than there is the back..


I imagine I get a red 2-sided audio plug and plug one into the amp and the other into the computer right? I don't know what the input hole is for, I imagine that may have to be plugged into the computer as well? What is the plug I need to make this work called?

Here are some other questions. I got to plug two different led light systems into the power supply (for the CP) will there be enough room to plug in this one for the amp?

Another question is, is that all the plug that need to be plugged in to make this amp work? Currently there are many wires in the cabinet and the speaker system is still grounded to the cab and I have no idea if there are more plugs to be found. Sorry I haven't done more looking into the cabinet but I been real busy as of late. But does what I said seem to be accurate?

Currently I have one of those power strips that will turn on everything once one thing turns on, the electronic that's currently in the a activation outlet is something that has a SWITCH to turn on and off. Everything that I tried that has a switch does not work to turn everything on.. My only guess the only thing that will work is something that is turned on and off by a button. Is that true? And if so, what do you suggest I use besides the PC itself (it will be deep inside the cabinet.) I was thinking maybe I can just get a different amp with a BUTTON that turns it on and plug that into the activation outlet to turn on everything, since it's up front. Would that work? Or do you guys have another idea?
