i got the walmart 2 amp install kit and when i was looking at everything, i saw the gold plated battery terminal that was 'for use with dual amp installation kit'. not knowing what i was doing, i figured i needed this. now after having everything open and viewing it.. the kit came with a short piece of 4g with a terminal ring on the end for the battery.. so whats the terminal for? did i waste $8? does anyone want it? :mad:
