WARNING: High-powered car audio systems may produce sound
pressure levels that exceed the threshold at which hearing
loss may result. They may also impair a driver’s ability to
hear traffic sounds or emergency vehicles. Use common
sense and practice safe listening habits when listening to
your audio system.
DUAL VOICE COIL WIRING
CAUTION: Never connect only one voice coil of a dual voice coil woofer.
Both must be driven at the same time for proper operation.
Never connect an amplifier to an impedance load lower than
it is rated to handle.
SERIES/P ARALLEL MONAURAL CONNECTION

result in a total impedance load of 1 Ohm at the amplifier, (See Fig. 1) if your
amplifier is rated to drive 1 Ohm in bridged or one-channel operation. If each of two
dual-voice coil 2-Ohm woofers are connected in parallel and then wired to each
wiring for a single, dual-voice coil 2-Ohm woofer in a monaural system will

other in parallel, a 0.5-Ohm monaural output would result (See Fig. 2). On the other
hand, if your amplifier is rated for 2-Ohm operation in bridged or one-channel operation,
series-connect the woofer voice coils (See Fig. 3). If the amplifier is rated for 4 Ohms,
interconnect the voice coils of the woofer in series as shown to obtain an 4-Ohm monaural output (See Fig. 4).

connect one woofer to each channel for 2 Ohm stereo operation (See Fig. 6), or two
parallel-wired woofers (one-per-channel) for 1-Ohm stereo operation (See Fig.7).

INSTALLATION RECOMMENDATIONS
To realize the utmost in sound reproduction from your subwoofer(s), follow these
installation recommendations:
l Use a quality large gauge wire to connect your subwoofer to the
amplifier
l Use a subwoofer crossover to remove unwanted higher frequencies
l Position the enclosure in the rear of the vehicle with the subwoofer
facing rearward to improve bass response and avoid cancellation of
audio frequencies
ENCLOSURE CONSTRUCTION RECOMMENDATIONS
T o enhance subwoofer performance, the following general recommendations should be
addressed when constructing the speaker enclosure:
l Use 3/4" MDF for your construction material
l Glue all joint seams
l Screw all joints tight
l Brace all walls
DESIGNING AND BUILDING YOUR SPEAKER ENCLOSURE
The following parameters are offered to assist you in designing your own enclosure.
There are many computer software programs available on the market that, along with
this information, will allow you to construct the type of enclosure that best suits your
needs.
To obtain the best possible results, we suggest you use our recommended enclosure
designs and have an automotive sound professional build your enclosure.
