Ahhhhh the joy of D.I.Y.! Wow think of all that money you saved! So why not come here and ask people who make a living installing this stuff for advice? I have a better idea, why not ask somebody who knows what they are doing before you go and buy stuff that you want to "figure out" on your own? You have a friend who is a speakercraft dealer yet you still chose to buy b-stock from the internet? I hope you saved enough money on your MZC system to cover the money you wasted on that fireball because it is not compatible with the system.
