Bridged to two channels, or bi-amped/bi wired? Otherwise just run one set of components to one channel, and the other set to another channel. The speakers will have their own passive crossovers, which you SHOULD NOT try to run without. Set the high-pass to aound 80 to 100Hz (depending on your components), and you'll have two channels still available to bridge to a sub!It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Each speaker has its own channel. My speakers 60w rms, 180 peak, @4ohms. So im already pushing it as it is.2004 F150 STX 4x4

So are you bi-wiring? Using all four channels of the amplifier to run the four drivers in the component sets? If that's the case, bypass the crossover on the low pass section, run those two channels to the tweeters through the crossovers, and put the woofers on the hi-pass (set at 80Hz) channels through the passive crossover. Then set the gains to how you like the sound. If I am misunderstanding your posts, elaborate a bit on the COMPLETE system setup. Your posts really don't tell us a lot about what you have, or how it's installed.It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice.
