Guys I need help. The 14g speaker wire I bought from home depot does not have anything to indicate which side is which? So my question is, while I am crawling through the attic how can I be sure I hooked up the + input of the speaker to the + output on the tuner and the same for the negative. Will it just sound bad if it is hooked up with the wrong polarity? Before I get flamed I checked the forums and could not find anything specific to tell me if I did it Wong. Please help this lowly newb.
