Subwoofer Wire Diagram

Image with text

Tutorial for multiple subwoofer systems/wiring, which often include dual voice coils (DVC) on each sub, the level of wiring intricacy can be enough to turn-off even the most experienced car audio do-it-yourselfers. Don’t worry; we have collected wiring diagrams of several configurations for dual voice coil (DVC) drivers.

Furthermore, if you have an idea for a wiring formation and you do not see it here, chances are you should re-think its application. You will more than likely find that the results will be less than best.

Single Woofer, Series Wiring

Connecting the two voice coils of the sub in series (+ to -) will score the following impedances:
Dual 4Ω Subwoofer: 8 Ohms
Dual 2Ω Subwoofer: 4 Ohms

Single Woofer, Parallel Wiring

Connecting the two voice coils of the sub in parallel (+ to +, – to -) will score the following impedances:
Dual 4Ω Subwoofer: 2 Ohms
Dual 2Ω Subwoofer: 1 Ohms

Dual Woofers, Series Wiring

Connecting the two voice coils of each sub in series (+ to -) and the subs themselves in parallel will score the following impedances:
(2) Dual 4Ω Subwoofers: 4 Ohm
(2) Dual 2Ω Subwoofers: 2 Ohm

Dual Woofers, Parallel Wiring

Connecting the two voice coils of each sub in parallel (+ to +, – to -) and the subs themselves in parallel will score the following impedances:
(2) Dual 4Ω Subwoofers: 1 Ohm
(2) Dual 2Ω Subwoofers: .5 Ohm

Three Woofers, Series Wiring

Connecting the two voice coils of each sub in series (+ to -) and the subs themselves in parallel will score the following impedances:
(3) Dual 4Ω Subwoofers: 2.67 Ohm
(3) Dual 2Ω Subwoofers: 1.33 Ohm

Three Woofers, Parallel Wiring

Connecting the two voice coils of each sub in parallel (+ to +, – to -) and the subs themselves in parallel will score the following impedances:
(3) Dual 4Ω Subwoofers: .67 Ohm (Find a .5Ω Stable Amplifier)
(3) Dual 2Ω Subwoofers: .33 Ohm (Ugh, Do Not Pass Go…)
