CROSSOVER MOUNTING
When choosing the mounting location of the crossover, accessibility is important. Adjustments to
the on-/off-axis setting and tweeter attenuation are to be made after the components have been
installed, so convenient positioning of the crossover is crucial. Also, the crossover has electronic
components that must be mounted so it does not come in contact with moisture.
WIRING
When installing these separates consider the age of the factory wiring and gauge (size) of wire. If
the vehicle is an older model or was pre-wired with small wire (18 gauge or less), running new high
performance wire (http://www.streetwires.com/products/speakerCable/microUltraCable.cfm) will be
necessary. The speaker wire should run from the amplifi er’s output terminals, under the carpet and
through the factory rubber boot (loom) that protects the wires in the inner door jam. If the factory
boot cannot be used, take other measures to protect these wires as best you can. Sometimes the
door has to be completely removed to use the factory boot. If this is something that you do not feel
comfortable doing, please ask a professional to help you. The wires should originate from the ampli-
fi er and attach to the crossover inputs.
CROSSOVER CONNECTIONS
Included with each TXC component system is a 2-way 18dB (tweeter)/12dB (midrange) octave
separate crossover network. The crossover networks allow each driver within the component system
to independently recreate frequencies within a precisely-designed range so that the speakers do
not become distorted by trying to reproduce frequencies that they are not physically able to. This
network ensures that the tweeter does not receive low bass notes and the mid-bass driver does
not receive high frequencies. The 18dB (tweeter)/12dB (mid) octave design complements both the
tweeter and mid and provides greater musical detail.
Note: Pay close attention to the markings on the crossover to be certain the correct speakers are in
the correct outlet. If a tweeter is accidentally asked to play the frequencies reserved for a mid-bass
driver, it will be damaged.

BI-AMP CONFIGURATION
These crossovers feature Bi-amp connections so that the components can be wired to drive the
tweeter and midrange independently using two amplifi ers. When using the components in the Bi-
Amp confi guration you are going to need two stereo amps or one four channel amp to run a pair of
components. You will need to remove the Bi-amp jumpers from the input connection points of the
crossover. Connect the desired amp or channels to the tweeter input. The second amplifi er, or third
and fourth channels of the 4-channel amplifi er, will be connected to the woofer input on the cross-
over. When the crossover is set up in this confi guration, the fi nal load will be 4 ohms.

Note: It is important to make sure the gain of each amplifi er is matched. Final gain level adjustments
should be made using the crossover settings.
