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/PARALLEL MONAURAL CONNECTION

Parallel wiring for a single, dual-voice coil 4-Ohm woofer in a monaural system will result in a total impedance load of 2 Ohms at the amplifier, (See Fig. 1) if your amplifier is rated to drive 2 Ohms in bridged or one-channel operation. If each of two dual-voice coil 4-Ohm woofers are connected in parallel and then wired to
