Where can I buy these Mach Audio MLI6.5? Not in the SSA store right only from the mach5audio.com website? I am also going to get some seas tweeter. I have an eclipse ea4000 so the woofers will be getting 75rms each and so will the tweeters. My headunit is a sony cd700 or whatever with graphic equalizer etc.... can I go active with it? Just with the headunit? This is my dumb idea. Cross everything over at 75hz and then play the woofers and mids, but obviously that isn't right? Anybody give me a hand or point me in the right direction if I'm doing this right? -Andres
