![]() Usually, this is regarded as the maximum wattage of the amplifier, and it is achieved by combining the positive signal of the first channel with the negative signal of the second channel.įor instance, if you’re looking to power a 150 watts subwoofer, you can decide to bridge a compact 4 channel amplifier rated at 30 watts RMS power per channel. Ideally, bridging amplifier channels helps double the amount of power that each channel could possibly put out. 4 Channel Amp to 1 Sub Wiring Diagram How amplifier bridging works At this point, the process of adding a single subwoofer is complete, and you can now go ahead and test your system. To prevent distortion, you may want to ensure that the signal transmitted to each voice coil terminal is exactly the same. You can use a screwdriver to clamp the cables securely into the amplifier’s terminals. For this step, you’ll need to run your cables from the third channel and fourth positive terminals to your subwoofer’s second set of voice coil terminals. ![]() ![]() The same wiring scheme will apply when connecting the third and fourth channels to the subwoofer. Step 4# Connecting the final set of terminals To achieve this, you’ll need to strip the wires (you can use a wire stripper to remove about 1 inch of the wire insulation) coming from the subwoofer before you can finally secure them to the amplifier terminals. Next, connect the subwoofer negative lead to the amp’s second channel negative terminal. Now, using the Y-splitter cable, you can start by connecting the first set of subwoofer positive terminals to the amp’s first channel positive terminal. Step 3# Connecting the amp to the subwooferįor this application, you’ll need to connect each channel to the designated voice coil terminals to increase the amount of power needed to drive the subwoofer. On the other hand, the two Y-splitter ends will be plugged into the RCA inputs found on the back of the subwoofer. When using a Y-splitter cable, you’ll need to plug one end of the wire into the SUB OUT port at the back of the amplifier. This adapter is specially designed to let you wire up each bridged channel to the subwoofer voice coils. The easiest way around this is using a Y-adapter to tap into the bridged amplifier channels. In addition, you may want to find of way of ensuring that the amplifier is delivering the same signal to the bridged channels. Step 2# Locating the subwoofer terminalsįor 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. ![]() As such, always double-check the specifications of your amplifier before you attempt any bridging work. Furthermore, some amplifiers come bridged internally, so attempting to bridge it further will only do more harm. Note: Never attempt to bridge an amplifier if the user manual does not indicate it is bridgeable. The good thing is that most bridgeable amplifiers indicate which terminals you need to use to facilitate bridging. Generally, a 4 channel amplifier should have a total of eight terminals i.e., one positive and one negative terminal for each channel as follows Once you’ve established if your 4 channel can be bridged, the first step involves taking note of the amplifier layout. How to bridge a 4 channel amp to 1 sub Step 1# identifying the amplifier layout As such, in order for you to safely bridge your amplifier, you may want to check the amplifier’s documentation to avoid causing irreversible damage to your car audio system. A dual voice coil subwoofer offers more wiring flexibility while also allowing you to choose an ohm load that will better match your amplifier recommended rating.īridging a 4 channel amplifier to drive one subwoofer is relatively easy, but it is important to note that not all amplifiers are bridgeable. You can bridge a 4 channel amp to a single sub provided that the subwoofer has dual voice coils. Now, can you use a 4 channel amp for 1 amp? However, in order for it to keep up with the rest of the components, it will need a huge amount of power. ![]() Normally, bridged amplifiers are mostly used in car audio applications to facilitate the transfer of a powerful mono signal to the subwoofer.Īdding a subwoofer to your car stereo helps lighten the load for the main speakers. Most audio amplifiers come with a bridge mode feature which allows you to combine the available channels into one channel with a more powerful output. ![]()
