Seems hard to find wiring diagrams for the audio systems anymore. 14 Taurus, Sony sound system with NAV. Does the sony amp output low-pass to the front door woofers and high-pass to the tweeters? Looking for a component setup for the front doors. For the time being, idea would be to hook the woofer and tweeter up to factory wires and not use the crossover. Once i get an aftermarket amp in there, id install the cross over. Hard to find 5x7 component setups, any one got any recommendations? Have found the Kicker components and JL. Kicker any good? JL's are pretty pricey. Thanks
