The woofer and the tweeter use .187 spade lugs for electrical connections. Use standard .187
female quick disconnects to attach wires to the speaker.
speaker mounting
woofer installation
The 3-series woofer will fit into standard factory mounting locations using the existing mounting
holes in the automobile. The woofer uses .187 spade type terminals for electrical connections.
To connect the woofer, use .187 or .205 female quick disconnects of a size appropriate for the
wire gauge you chose. You may also solder wire directly to the terminals. If you choose to solder
the wires, be careful not to use excessive heat so you do not melt the plastic around the terminal,
which is not covered by the warranty
Remove the trim panels and inspect the installation locations before you cut and drill the holes
required to mount the woofer. Removing the panel will also make it much easier to route wiring
inside the door. Look for original equipment speaker installation cutouts that can be used to
install the 3-series woofers with little or no modifications. Use the template supplied to help you
locate and mark the holes needed to install the speakers.
If the planned installation location is in a door panel be sure the speaker will not interfere with
the window lowering mechanism. Be sure that the speaker wires clear all moving parts inside
the door.
For each woofer you will need to cut one large hole and drill small holes around the circumference.
If the mounting surface is covered by carpet or fabric, use a knife or razor to cut the material
away from the holes and cutting path. This prevents material or fibers from becoming tangled in
the drill bit or cutting blade.
If you are using the sheet metal screws provided in the hardware kit, drill the four speaker
mounting screw holes with a 1/8" / 3mm drill.
Clean the work areas of all filings and shavings with a vacuum cleaner before you proceed with
woofer mounting.
woofer mounting
Route the speaker wire from the woofer installation locations to the crossovers. Pull the wire
through the installation hole and attach the terminals on the ends to terminals on the speakers.
Connect the positive wire to the positive (+) terminal, which is indicated by a “+” on the speaker
magnet. See the information in the speaker wiring section of this manual and the wiring diagrams.
Push the wire back into the area behind the installation location and be sure it will not interfere
with the speaker.
Adhere the supplied foam gasket strip to the mounting surface of the speaker. This will ensure
an air tight seal, which is required to achieve the best bass performance.
When installing the speakers drive the supplied sheet metal screws by gradually tightening them
in turn. Drive the screws in until the speaker is well seated, but take care not to over-tighten the
screws.
Each of the 3-series woofers is installed in a slightly different way. See the following illustrations
connections to crossover network and radio or amplifier
route the wires connected to the input terminals on the front of the crossover network to the
power amplifier (or, if you are not using a separate power amplifier, the in-dash radio/tape or CD
player). Connect the wires to the amplifier outputs as recommended by the manufacturer of the
unit. Make sure there are no stray strands of wire which could cause a short circuit. Observe left
/ right and polarity markings.
bi-amplified connections to the crossover network
connections to the woofer and tweeter are the same as the normal wiring method. Connect the
amplifier you have chosen for the tweeter to the terminals marked high input. Connect the
woofer amplifier to the low input terminals.
Important note - you must cut the jumpers that connect the low frequency and high frequency
sections of the crossover. See diagram . Failing to cut these jumpers could cause damage to the
amplifiers or the crossover.
for biamp operation cut these jumpers
