Bridging a subwoofer is an effective way to enhance the sound high quality of your own home audio system. By connecting two subwoofers collectively, you possibly can create a extra highly effective and immersive bass expertise. On this article, we’ll offer you a step-by-step information on the way to bridge a subwoofer. We may even focus on the advantages of bridging subwoofers and supply some suggestions for troubleshooting frequent issues.
Earlier than you start, you will need to guarantee that your subwoofer is appropriate with bridging. Not all subwoofers might be bridged, so you will need to examine the producer’s specs. Upon getting confirmed that your subwoofer is appropriate, you possibly can comply with these steps to bridge it:
1. Flip off the ability to your subwoofer and disconnect all cables.
2. Find the speaker terminals on the again of the subwoofer. There must be two units of terminals, one for every channel.
3. Join the optimistic terminal of 1 subwoofer to the optimistic terminal of the opposite subwoofer.
4. Join the damaging terminal of 1 subwoofer to the damaging terminal of the opposite subwoofer.
5. Activate the ability to your subwoofer and join the cables to your audio system.
Selecting the Proper Subwoofer
Relating to bridging a subwoofer, the primary and most necessary step is selecting the best subwoofer. Not all subwoofers are created equal, and never all of them are appropriate for bridging. Right here are some things to bear in mind when selecting a subwoofer for bridging:
- Energy dealing with: The facility dealing with of a subwoofer refers back to the quantity of energy it could deal with with out being broken. Once you bridge a subwoofer, you might be primarily doubling the ability that’s despatched to it. Due to this fact, you will need to select a subwoofer that has an influence dealing with that’s not less than twice the ability of your amplifier.
- Impedance: The impedance of a subwoofer refers back to the resistance it presents to the stream {of electrical} present. Once you bridge a subwoofer, you might be primarily connecting two subwoofers in parallel. This halves the impedance of the system. Due to this fact, you will need to select a subwoofer that has an impedance that’s appropriate together with your amplifier.
- Measurement and enclosure: The dimensions and enclosure of a subwoofer can even have an effect on its suitability for bridging. Bigger subwoofers are inclined to have extra energy dealing with and decrease impedance than smaller subwoofers. Moreover, subwoofers which can be enclosed in a sealed enclosure are inclined to have the next energy dealing with than subwoofers which can be enclosed in a ported enclosure.
Upon getting thought of all of those components, you need to have the ability to select a subwoofer that’s appropriate for bridging.
| Energy Dealing with (Watts) | Impedance (Ohms) | Measurement | Enclosure |
|---|---|---|---|
| 500-1000 | 4 or 8 | 12″ or 15″ | Sealed |
| 1000-2000 | 2 or 4 | 15″ or 18″ | Ported |
Connecting the Subwoofer to an Amplifier
Connecting a subwoofer to an amplifier is a comparatively easy course of, however there are some things you want to bear in mind to make sure that you do it appropriately. Step one is to decide on the suitable sort of amplifier in your subwoofer. Amplifiers are sometimes categorised by their energy output, so you will must guarantee that the amplifier you select has sufficient energy to drive your subwoofer. As soon as you have chosen an amplifier, you will want to attach it to your subwoofer utilizing a speaker cable. The speaker cable must be thick sufficient to deal with the quantity of energy that the amplifier will likely be delivering to the subwoofer.
As soon as you have linked the amplifier to the subwoofer, you will must activate the amplifier and modify the quantity to a cushty stage. You might also want to regulate the crossover frequency on the amplifier to make sure that the subwoofer is barely reproducing the low frequencies that it is designed to deal with.
Bridging a Subwoofer
Bridging a subwoofer is a way that can be utilized to extend the ability output of a subwoofer. Bridging includes connecting the optimistic terminal of 1 amplifier channel to the optimistic terminal of the subwoofer and the damaging terminal of the opposite amplifier channel to the damaging terminal of the subwoofer. This creates a single, extra highly effective sign that’s despatched to the subwoofer. Bridging a subwoofer generally is a great way to enhance the efficiency of a subwoofer in a big room or in a system with a number of subwoofers.
Desk: Bridging a Subwoofer

|---|---|
| Optimistic terminal of left amplifier channel to optimistic terminal of subwoofer | Connects the optimistic sign from the left amplifier channel to the subwoofer. |
| Damaging terminal of proper amplifier channel to damaging terminal of subwoofer | Connects the damaging sign from the suitable amplifier channel to the subwoofer. |
When bridging a subwoofer, you will need to use an amplifier that’s rated for bridged operation. Bridging an amplifier with an amplifier that isn’t rated for bridged operation can harm the amplifier.
Figuring out the Optimum Crossover Level
The crossover level is a crucial think about bridging a subwoofer, because it determines the frequency vary that the subwoofer will reproduce. The perfect crossover level varies relying on the scale and specs of the subwoofer, in addition to the general sound system.
To find out the optimum crossover level, contemplate the next components:
- Subwoofer Measurement: Bigger subwoofers can sometimes deal with decrease crossover factors, whereas smaller subwoofers are higher suited to larger crossover factors.
- Subwoofer Frequency Response: The subwoofer’s frequency response signifies the vary of frequencies that it could reproduce. The crossover level must be set inside the subwoofer’s frequency response vary.
- Room Measurement and Acoustics: The dimensions and form of the room, in addition to the position of the subwoofer, can affect the optimum crossover level.
The next desk supplies a normal guideline for figuring out the optimum crossover level primarily based on subwoofer dimension:
| Subwoofer Measurement | Optimum Crossover Level |
|---|---|
| 8-inch | 80-120 Hz |
| 10-inch | 60-100 Hz |
| 12-inch | 40-80 Hz |
| 15-inch | 30-60 Hz |
Upon getting thought of these components, you possibly can fine-tune the crossover level by listening to your system and adjusting it till you discover the sound that most closely fits your preferences.
Deciding on and Putting in a Line Degree Enter Converter (LILC)
A line stage enter converter (LILC) is a tool that lets you join a subwoofer to a automotive stereo that doesn’t have a devoted subwoofer output. LILCs convert the high-level speaker indicators from the automotive stereo into low-level RCA indicators that can be utilized to connect with the subwoofer’s amplifier.
When deciding on a LILC, you will need to select one that’s appropriate with the impedance of your automotive stereo and the ability output of your subwoofer amplifier. The impedance of your automotive stereo is often 4 ohms or 8 ohms. The facility output of your subwoofer amplifier is measured in watts RMS. Upon getting chosen a LILC, you have to to put in it in keeping with the producer’s directions.
