It is always best to plan the complete installation prior to attempting
to install any product. The routing of wires, power connections and mounting
locations should be planned rst. As with any car stereo installation, all work
performed should be checked thoroughly and carefully prior to the operation of
the system.
The placement of your Alphasonik speakers within your vehicle will
greatly affect the overall performance of your audio system. Installation in
every vehicle may not be possible without modications. Factory provided
locations are generally preferable due to ease of installation. In all cases
speakers should be placed in a location free of obstruction by body panels,
window cranks, storage compartments or anything that may hinder the
speaker’s performance. Avoid areas that do not provide a at, sturdy
mounting surface.
Alphasonik speakers are designed to t in almost any factory location.
Again, if at all possible, it is recommended that you use a factory location.
This applies mostly to later model vehicles. For those earlier models that do
not have factory locations or are limited to front locations, it is recommended
that you choose an area with sufcient air space.
If you allow an insufcient amount of air space, the speaker may not
reproduce low frequencies very well. It is recommended to mount the
speakers in door panels, kick panels, rear decks, etc. Ideally, the speaker
should be mounted where it will be in an enclosed airspace, allowing for
extended bass response.
INSTALLATIONINSTALLATION

NOTE: Alphasonik strongly recommends that you operate your system at
low volume prior to the completed installation of your Alphasonik speakers.
This will allow a test of the speaker before securing it to its permanent
location.
CAUTION: Make sure that all speaker wiring is fully protected from cuts,
tears and possible wear. Any short circuit developing as a result could
severely damage the source unit or possibly the amplier. Make sure all
speaker wires easily reach the speaker terminal with no stress on the wires
or connectors.
MOUNTING:
1. Conrm the mounting location and depth requirements by inspecting the
area where the speaker will be mounted. Most speakers will t into stock
locations on the vehicle, in this case only depth is important.
2. If the location you have picked does require cutting, use the hole cutout
measurement from page 4 and mark the mounting location.
3. If there is a cosmetic panel where the speaker will be mounted, we
recommend using a utility knife to carefully cut a hole in it. Conrm the
cut by placing the speaker in the hole. You may modify the hole as
necessary.
4. If it will be necessary to cut steel, reinstall the cosmetic panel in place
and use the hole you have previously cut as a template. This will help
to insure proper cutting and a good t. Mark the location for the speaker
mounting screws, remove the panel and drill the screw holes. When
nished you may replace the panel.
5. After cutting and drilling all holes, inspect the mounting areas for any
metal burrs or rough edges. File any area that may interfere with the
mounting of the speaker.
6. Clean any metal shavings from the mounting area and check for areas
in which water may enter the speaker cavity. Treat the area for water
protection when necessary.

Make sure your source unit (CD, DVD, etc) is turned off while
connecting the speaker terminals. Turn on the various components and
slowly advance the volume. Remember to check and recheck all connections
to insure proper use.
1. Alphasonik recommends using at least 18-gauge wire with your new
speaker system. Thinner gauge wire may easily be severed and can
cause damage to your system should any bare wire come in contact with
the vehicle’s chassis.
2. Make sure that your audio system is off while installing and connecting
your new Alphasonik speakers. Failure to do so could result in damaging
the speaker beyond repair.
3. Be sure to route the wires to the speakers with the insulated terminals
ending at the speakers. This will insure a good contact with the speaker.
If you need to shorten the speaker lead, do so at the opposite end of the
insulated terminals or the bare end.
4. Be sure the polarity is correct at all times. The speaker leads are
color-coded for negative and positive. Be sure that the leads are
connected to the correct terminal of the speaker.
5. To insure long-term reliability, all bare wires and wire-to-wire connections
should be soldered and insulated with heat shrink or electrician’s tape.
Under no circumstances should you leave any bare wires uncovered, as
this can and will lead to the damage of your speakers.
6. When mounting in a door, it is imperative to have the right amount of
slack in the connecting wire so it does not get crimped or torn when the
door is opened and closed. Avoid areas of the door jam that pinch, this
will cause damage to the speaker over long-term use.
7. Once the speaker wiring is completed you can connect the opposite end
to the source unit or amplier. Again, be sure to observe the correct
polarity. Solder and wrap all stripped connections.

Once you have tested your system and have conrmed that it is
operating properly, turn off your system and prepare for the nal mounting
of the speakers.
1. Position the speaker into the mounting hole and reconrm the
correct mounting location and hole placement. Screw clips are
provided to insure a snug t. Place screw clips over the metal surface
and line up the hole with the hole you have previously drilled. Place the
speaker into the hole, align the mounting holes and proceed to insert
the screws. Be sure to tighten the screws evenly as to not warp the
speaker frame.
2. Turn your system back on and conrm the speaker’s operation, rst at
low volume and then you may increase the volume as you desire.
3. Carefully inspect the speakers surrounding and make sure the area
does not obstruct the mounting of the grill.
