Signal Cable Tips
- Don’t Do This...
When routing your signal cables you want to avoid placing them directly next to any factory wiring harness or
other 12 volt power wiring. (Fig. 1 & Fig. 2) If you route your cables like this, you greatly increase the possibility of
your system picking up noise. If you absolutely have to do this, refer to Figure 6 and Figure 7 on page 9 and keep
the distance they run together as short as possible. Or better yet...Don’t Do This.
When routing your signal cables, do not coil or tie the cable into loops or bundles. (Fig. 3, Fig. 4, Fig. 5) Doing
this enhances the wires ability to act as an antenna and will increase the chances that the cable will pick up induced
noise from the car or other wiring and inject it into your audio system.
Finally, do not use an excessively long interconnect cable. (Fig. 6) You want to use just enough cable to get from
your source unit to the KQ30 and just a little bit extra for usability and serviceability. Typically 6-12 inches per end is
plenty of extra cable to accomplish this.
For example, if the distance from your
source unit to the KQ30 is 17 feet (Dashed
line in Fig. 6) then use a cable no longer
than 19 feet. Do not use a 25 foot cable.
Using more cable than you need leads to
the problems described above in Figures
3,4 and 5.
