This is an optimal crossover setting on most vehicles. inverting phase Depending on the placement of your subwoofer enclosure and associated components, it may be necessary to invert the phase of one or another of your system's connections in order to gain better subwoofer/mid-range blending. Inverting the phase simply means switching the positive connections with the negative connections at the amplifier. If you choose to do this, invert the phase of only one set of speakers (either your mains, or your subs, never both). low frequency cut-off for mid-range speakers in systems with subwoofers Now that you have a subwoofer in your system, you may want to decrease the amount of bass going to your midrange speakers. This will get you better mid-range sound and increase the power handling. There are two ways to roll off the bass before it gets to your mid-range speakers. One way is to use a "bass blocker," a capacitor placed in series with the speaker input. Bass blockers are installed in series, one end connected with the positive lead from your amplifier and the other end connected to the positive lead of each of your speakers. Bass blocker capacitors (200 microfarad @ 100V, non-polarized) are available at any Radio Shack or electronic parts supply house. The other route is to use an electronic crossover device that allows filtering below 100Hz or so. Find these devices at your authorized Polk dealer. 14 DXi: high performance car speakers more information @ www.polkaudio.com 15
