Before you start the process
of replacing speakers,
disconnect and secure the
negative terminal from your
battery/power source. This
will prevent the risk of
damaging yourself or the
products.
Place the disconnected terminal in a secure and
isolated location away from any possible
connection belonging to the battery/power source
system. Speaker connection
Make sure you connect the cables with correct
polarity on the speaker terminals. Observe the
markings and size differences on the connectors.

Installation
Mount the speakers in the door or in the rear shelf
of your car. They may fit in the factory pre-made
mounting holes, if not you might have to modify
the fitting. If you want to improve the sound
reinforcement you can use a baffle of MDF-board
or similar. For door placements, there are normally
speaker rings that have to be used to make the
speaker fit to the door panel.
NOTE! It is important to fasten the speakers
properly in order to avoid bad sound or rattling.
General installation
Custom baffle installation
It is very important that the custom baffle are
stable and fasten properly, but it is just as
important that it´s shaped in a way that the driver
is allowed to “breathe” correctly. Bass reproduc-
tion will be enhanced when the air flow is free and
not obstructed.

Speaker phasing
To be sure that the CRPP-UW64 woofer are using
the correct polarity (phase) after installation, it is
possible to check this easily by using a 1.5 volt
battery.
Connect the battery’s positive and negative pole
to the speaker cable. If the speaker is correctly
connected the cone should move outwards. This
need to be tested on all left/ right pairs to make
sure all drivers are in phase with each other.
Note!
Don´t use this testing method on tweeters or
other low excursion drivers without a correct
connected high pass crossover.
