I have the equipment that tex sold me like two years ago and I intend on hooking it up in my car so far so good. I've got infinity kapas in the back, getting a set of component kapas for the front, and i'm going to take the infinity reference that are in the front and put them in the back seat doors, maybe next year I will put in a pair of 10's in the trunk. Everything except the rear seat will be run off a pair of amps, the back seat will be run off of the head unit. The only thing that I'm having a problem with planning is the crossover has two inputs and three outputs, the inputs are for front and rear speakers off the head unit and the outputs are front, rear, and SW. My head unit has front, rear, and SW outputs. I was hoping to use all three of the outs off the head unit and run them all to the cross over. So right now I see a few paths. 1) Use the F+R off the head unit and the three out of the crossover. 2) Use the F+R+SW off the head unit and run the SW directly to the SW amp. 3) Buy a new crossover that has three imputs, a alpine so I could control the crossover from my head unit. 4) Use the F+R+SW off the head unit. Run the SW out of the crossover to one of the channels of the SW amp and run the SW out of the head to the other channel. I'm not sure if this method would work, or if its even worth it. Let the voting begin!
