CROSSOVER MOUNTING
When choosing a location to mount the crossover, accessibility is important.
Adjustment will need to be made like tweeter attenuation.  Keep in mind the cross-
over has electronic components inside, and must be mounted so that no moisture 
can make contact.
WIRING
Two things to take into consideration when installing these separates is 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 amplifi er 
and attach to the crossover inputs.
CROSSOVER CONNECTIONS
Each TX speaker system has a 2-way 18dB/6dB oct separate crossover network. The 
crossover networks allow the drivers to recreate the frequencies within a precisely 
designed range so that the speakers do not become distorted by trying to reproduce 
frequencies that they are physically unable to reproduce. This feature ensures that 
the tweeter does not receive low bass notes and the mid bass driver doesn’t receive 
high frequencies. The 18dB (tweeter)/6dB (mid) oct means the slope, or the amount 
of other frequencies that will be affected, is fairly narrow. This design complements 
both the tweeter and mid and provides greater musical detail. 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. 
CROSSOVER CONNECTIONS FOR TX1000
Separate 1-way 18dB/oct crossovers are included with the TX1000 tweeters, which 
allows the drivers to recreate the frequencies within a precisely designed range. This 
ensures that the speakers do not become distorted by trying to reproduce frequencies 
that they are physically unable to reproduce. The 18dB/oct means the slope, or how 
many other frequencies will be affected, is fairly narrow. This design complements 
both the tweeter and mid-bass to provide greater musical detail.
