Congratulations on your purchase of the Prestige High Performance Subwoofer. The Prestige Subwoofers are designed to provide you with high quality Bass reproduction required to make your car audio system perform to its full potential.
two dual-voice coil 4-Ohm woofers are connected in parallel and then wired to 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 8-Ohm monaural output (See Fig. 4). PARALLEL SERIES - + 2Ω 8Ω 2Ω MONO - + - + Fig.
SERIES/PARALLEL CONNECTION USING THREE WOOFERS Three dual 4-Ohm voice-coil woofers can be connected in such a way as to produce a 0.66-Ohm (See Fig.8) or 2.66-Ohm monaural output as shown below (See Fig.9). + 2Ω - + - + 2Ω - + 0.66 Ω - + 2Ω- - + + - Fig. 8 + 4Ω - + + 4Ω - - + 2.66 Ω 4Ω - + + Fig.
