well if you have a seperate amp for the speakers, just set the amp to HI so all it recieves is the hi frequency's and no bass would go through, like my amp has HI/LO/BOTH which basically means PURE TREBLE/PURE BASS/BOTH MIXED
I think im going to go ahead and buy a crossover. I have around 50 bucks to spend on it, and i can buy off ebay so things are alot cheaper. I do want to hook up both my 5 1/2 and my 6x9 with it. Thanks
