Make a cut in the length of the speaker wire that will be required to connect the amp input to the speaker output. It would be best to think about the path you’ll use to get your wire from your amp to your speaker and back again. Using a quarter-inch strip on each end, strip the wire. The ends of the wire will be inserted into the terminals of the amplifier and speaker wires.
Connecting a 4-ohm amplifier to a 2-ohm speaker is standard practice for vehicle stereo enthusiasts. The amplifier will only function properly if the amplifier is connected to the speaker correctly. Improper wiring can fail the amplifier and speaker. The audio system of your vehicle must be wired correctly to achieve the finest sound quality possible.
Compared to the same model with a single voice coil construction, two voice coil subwoofers are typically slightly more expensive – but not by a significant amount. Even though the power handling ratings usually are pretty similar, they may vary somewhat.
Steps on wiring dual ohm speakers for factory amplifiers
|Disconnect the battery||To prevent the power flow|
|Cut the speaker wire.||To connect the amp input to the speaker output||Check the 4-ohm speaker from Amazon|
|Strip a quarter-inch wire||To insert the wires respectively||Speaker wires|
|Connect the positive wires to the positive port||This will allow a successful power flow|
Step 1; disconnect your battery
This will prevent power from flowing to your amplifier or the speaker.
Step 2; cut the speaker wire you need from the amp
Make a cut in the length of the speaker wire that will be required to connect the amp input to the speaker output. It would be best to think about the path you’ll use to get your wire from your amp to your speaker and back again.
If you want to know the amplifier I use, check the 4-ohm amplifier from Amazon.
Step 3; strip a quarter-inch wire
The ends of the wire will be inserted into the amplifier and speaker wire terminals, respectively.
Check the wires from Amazon
Step 4; connect the positive wires
For this to work, a wire labelled with red should be connected to the positive input of the amplifier and the speaker. Make a connection between the negative wire (designated white) and the negative information on the amplifier and speaker.
If you want to know the wires I use, check the amplifier wires from Amazon.
Choosing the suitable dual voice coil subwoofers
A few considerations must be made to get the best dual voice coil subwoofers:
- Knowing your amplifier’s minimum speaker load at the power level you’re considering is essential.
- What number of subwoofers you’d like to employ
The rest is relatively straightforward! Refer to the wire connection diagrams below to determine which subwoofer(s) layout is appropriate for your system.
You’ll need to consult the amplifier’s owner’s handbook (or the labelled printed version) to determine the most negligible speaker load that can be used, as well as the highest power rating Ohm load that can be used. Then select the appropriate quantity of dual voice coil sound systems that can be linked together to provide the amplifier’s output.
Advantages of dual voice coil subwoofers
1. Maximum power output
Nowadays, most automobile amplifiers have specific output ratings (in Watts) when used with a specific speaker load resistance (in Ohms).
Consider the following scenario: you want to employ a single (mono) bass arrangement with only one subwoofer. Normally, you’d be limited to a maximum output power of 600W from the amplifier because most subwoofers are only 2 ohms or more in resistance.
While it is possible to add a second 2-ohm subwoofer and wire them both in parallel, doing so would necessitate purchasing a larger box, spending more money, taking up more mounting space, and so on.
It is possible to use a 2 ohm DVC subwoofer wired in parallel with the amplifier to allow the amp to produce its total output. Aside from that, you will never be able to achieve the energy capacity you purchased with your amplifier.
This is especially relevant nowadays, given that modern class D amps have ratings along these lines, and some can drive 1-ohm loads.
2. Unique setups and amp channels
As I already stated, not all amplifiers can be bridged at the same time. For example, if you have a single 4-channel amplifier, this is a significant problem. Adding a subwoofer and supplying it with enough power without purchasing a second amplifier is difficult.
In the case of a dual voice coil woofer, you might use one line for each of the voice coils to drive the subwoofer at a sufficient power level. Additionally, for robust systems, it is feasible to use one amp per voice coil for single or many subwoofer systems, depending on the configuration.
3. Amplifier impedance matching
When connecting multiple subwoofers to the same amplifier channel, or when mono bridging different channels, the Ohms load that the amplifier encounters is determined by the subwoofers’ series or parallel wiring configuration.
Dual voice coil subs give you numerous more alternatives since they let you choose from a more significant number of total Ohm combinations that can better fit the minimum rating of your amplifier.
4. Ability to be used for car stereo systems
A typical 8-ohm subwoofer cannot be used efficiently for automotive audio since it cannot provide the same amount of power as 4-ohm speakers of the same type. Car subwoofers with two or 4-ohm ratings cannot be utilized with home stereo amplifiers to avoid exceeding the minimum amplifier specification.
The result will be an overheated home amplifier that will eventually fail or be irreparably damaged.
A unique advantage of twin voice coil speakers is that they may be used as a dual 4-ohm subwoofer for automobile and residential applications: 8 ohms are achieved by wiring the speakers in series.
A single 4-ohm resistor or two 4 ohm resistors paralleled together are recommended when using a car stereo amplifier. Using speakers at a low cost is highly advantageous if you can find them at a low price. Otherwise, you would be unable to use them.
