![]() Be aware of the fact that if your amplifier is a stereo amplifier (amplifying both left and right), bridging it would cause it to become a mono amplifier (amplifying from one either the left or right).It may already be bridged internally, and you could cause damage to your amplifier. For you to bridge a 4 channel amp to one subwoofer, you’ll need to ensure that there is a signal on all channels of the amp. If your amplifier does not claim to be able to bridge, don't try to bridge it. 800 Watt 4 Ohm Car Subwoofer Speakers and (1) Audio Stereo Amplifier. When bridged it is rated at 150 x 2 at 4 ohms. I have (3) 4 channel amps that have been sitting in the garage for awhile and Ive decide that rather than buying yet another new amp I will use one of these to power a sub. Most amplifiers have a small diagram near the channels indicating the terminals you would use to bridge it. MAX 4 Ohm Dual Voice Coil Car Subwoofer Speaker with 2 Channel 1000 Watt Amp. Using a 4 channel Amp to power a Polk Audio db1040 DVC sub. ![]() Be sure to check your manual (or the manufacturer’s website) to see if once connected to a speaker, whether or not your amplifier can function at half the ohms it currently uses. Bridging an amplifier cuts the resistance load (measured in ohms) in half, which can cause it to overheat.If the amplifier is used, or lacks documentation, go online and check for the specifications on the manufacturer's website. This should be indicated on the documentation pamphlets that came with the amplifier, or the amplifier itself. Six Dual Voice Coil Speakers in Series / ParallelĬonnecting the two voice coils of each driver in series (+ to -) and the drivers themselves in parallel (+ to +, etc.Make sure your amplifier can be bridged.

A DVC 4-ohm sub can be wired into a system as a 2-ohm or as an 8-ohm load. Three DVC drivers with Voice Coils in Series / Parallel Subwoofer manufacturers make subs with dual voice coils (DVC) to take advantage of this difference in wiring schemes, so the user has more freedom of system design. Two Dual Voice Coil Speakers in Parallel / ParallelĬonnecting the voice coils of each driver in parallel (+ to +, - to -) and the drivers themselves in parallel (+ to +, etc.) will result in the following impedances: Mono amps: mono amps are a case of it depends there are 4 stable, 2 stable, 1 stable, and even 1/2 stable amps although 1/2 is a bit rare. Two DVC drivers with Voice Coils in Parallel / Parallel 5 channel car amps: Like 4 channel amps, 5 channel amps are usually also 2/4 (stereo/bridged mode) rated while the 5th (subwoofer) channel can be 2 or 4 in some cases.

For more information, please consult our Dual Voice Coil FAQs.Īdditionally, if you have an idea for a wiring configuration and you do not see it here, chances are you should re-think its implementation (in other words, don’t do it). This does not include series connections made between voice coils on the same driver. Please note that when wiring multiple drivers it is recommended that series connections between drivers be avoided at all costs. Fear not, though, for we have compiled wiring diagrams of several configurations for dual voice coil (DVC) drivers. With multi-driver sub systems, which often feature dual voice coils (DVC) on each driver, the level of wiring complexity can be enough to turn-off even the most adventurous of car audio do-it-yourselfers.
