I'm replacing my 4 channel amplifier to another 4 chan amp, and looks like I need some help doing this. From what I can see, it's pretty simple REPLACING an existing amp, as all the connections will be same to the new one. So, I took out all my RCA Cables, Speaker wires, and Ground, Remote, +12v cables from the Old AMP and now I'm putting them in the new Amp..But, when I try to put the GRND, And Battery cables into the slots in my amp, that **** SPARKLES!!! WTF, Why is it sparkling? This scared the **** outta me..how do I correctly put the GRND, BATTERY, Cables into the slot without sparks?
