Integrated Impedance Selector

To help installation, Cerwin-Vega Mobile designed a simple but effective single terminal Dual Voice coil setup. Simply pull out the terminal, rotate it to the impedance desired. The impedance above the terminal is the impedance of the driver now, with only one set of speaker wires going to it. No complicated wiring anymore!!!

Illustration of the terminal block with an arrow indicating rotation for impedance selection. A note indicates "* The sub shown is wired into a 1 ohm load (1Ω)".

Wiring Configuration

VEGA subwoofers (V65DV2/V65DV4) feature dual 2Ω or 4Ω voice coils. It is essential that both coils be connected to an amplification source. When the dual 2Ω voice coils are wired in parallel, they present a 1Ω load to the amplifier, while wiring them in series results in a 4Ω load. Similarly, for the dual 4Ω voice coils, a parallel connection yields a 2Ω load, and a series connection provides an 8Ω load. Make certain that your source unit or amplifier is rated for the appropriate ohm load to ensure proper operation.

The illustration below shows how to wire V65DV2 and V65DV4.

Series Wiring

Dual 2Ω Voice Coils = 4Ω Load
Dual 4Ω Voice Coils = 8Ω Load

Parallel Wiring

Dual 2Ω Voice Coils = 1Ω Load
Dual 4Ω Voice Coils = 2Ω Load
