I' gonna hook up my crossovers but i came to a snag. I have passive power acoustik x overs and they have 8 hook ups. 2 are the inputs 2 are the woofer out puts and the other 4 are the tweeter outputs this is the problem. I have 1 negative and three positives for the tweeters. -6, -3, and -0 dB. What is the difference between the three or which one should I use?? There is nothing in the instructions about it.
