each other in parallel, a 1-Ohm monaural output would result (See Fig. 2). On the  
other hand, if your amplifier is rated for 4-Ohm operation in bridged or one-channel  
operation, series-connect the woofer voice coils (See Fig. 3). If the amplifier is rated  
for 8 Ohms, interconnect the voice coils of the woofer in series as shown to obtain an  
8-Ohm monaural output (See Fig. 4).  
The same applies for parallel wiring of a single, dual-voice coil 6-Ohm woofer, in  
which a total impedance load of 3 Ohms will be seen at the amplifier.  
SERIES/PARALLEL STEREO CONNECTION  
Series wiring of each of two, dual voice-coil 4-Ohm woofers will result in a total  
impedance load of 8 Ohms at each channel of the amplifier (See Fig. 5). Otherwise,  
connect one woofer to each channel for 4-Ohm stereo operation (See Fig. 6), or two  
parallel-wired woofers (one-per-channel) for 2-Ohm stereo operation (See Fig.7).  
The same applies for series wiring of a single, dual-voice coil 6-Ohm woofer, in which  
a total impedance load of 12 Ohms will be seen at the amplifier.

INSTALLATION RECOMMENDATIONS  
To realize the utmost in sound reproduction from your subwoofer(s), follow these  
installation recommendations:  
Use a quality large gauge wire to connect your subwoofer to the  
amplifier  
Use a subwoofer crossover to remove unwanted higher frequencies  
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  
To enhance subwoofer performance, the following general recommendations should  
be addressed when constructing the speaker enclosure:  
Use 3/4" MDF for your construction material  
Glue all joint seams  
Screw or nail all joints tight  
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.
