How to Wire Rear Speakers in a Car

If you’re looking to add some extra bass to your car’s audio system, then installing some rear speakers is a great way to do it. But before you start shopping for speakers, you’ll need to know how to wire them up. This article will show you how to wire rear speakers in a car so that they work properly and sound great.

You’ll need a few things before you get started: speaker wire, wire strippers, electrical tape, and something to cut the holes for the speakers (if necessary).

Megane 2 – Rear door speakers installation and wiring

  • Choose the location for the rear speakers
  • Consider both aesthetics and sound quality when making your decision
  • Mount the speakers in their chosen location
  • Use screws or bolts to secure them in place
  • Connect the positive terminal of the first speaker to the positive terminal of the car’s stereo system
  • Do the same for the negative terminals

How to Wire Car Speakers Without Harness

If you’re looking to upgrade your car’s audio system by installing new speakers, you might be wondering how to wire them up without a harness. While it’s not the easiest task in the world, it is possible to wire car speakers without a harness, and we’ll show you how in this blog post. First things first, you’ll need to remove the old speakers from your car.

This will give you access to the wires that are currently connected to them. Once you have access to the wires, you’ll need to cut them off so that they can be replaced with new ones. Next, take your new speakers and connect the positive wire (usually red) to the positive terminal on the speaker, and then do the same for the negative wire (usually black).

Now it’s time to test out your new speakers! Turn on your radio or music player of choice and see how they sound. If everything sounds good, then congratulations – you’ve successfully installed new speakers without a harness!

Which Rear Speaker Wire is Positive?

If you’re looking to install a new car stereo or other audio system, you’ll need to know which rear speaker wire is positive. This can be a bit tricky, as there are usually four wires (left front, right front, left rear, and right rear). However, there are a few ways to figure out which one is which.

First, take a look at the wiring harness that came with your stereo. It should have labels for each of the wires. If not, most aftermarket stereos will use standard colors for the wires (red for positive, black for negative).

If you’re still having trouble figuring it out, another method is to use a multimeter to test the resistance of each wire. The positive wire will have less resistance than the others. Once you’ve identified the positive wire on your rear speakers, connect it to the corresponding terminal on your stereo.

Do the same for all four speakers and you’ll be ready to enjoy some great sound!

What Color Wire is Rear Speakers?

Rear speakers are typically red or white, but can be any color. The most important thing is to ensure that the rear speakers are connected to the correct output on the receiver – typically this will be labelled as “rear” or “surround”. Once you have made the connections, turn on your receiver and test to make sure that the sound is coming through clearly.

If not, check your speaker wire connections and make sure that they are tight.

How Do I Add Extra Speakers to My Car?

If your car didn’t come with built-in speakers and you’re looking to add your own, there are a few things you’ll need to take into account. First, you’ll need to decide what type of speakers you want. There are two main types of car speakers: full-range and component.

Full-range speakers are the most common and typically the most affordable option. They include a woofer for low frequencies, mid-range drivers for mids, and tweeters for highs all in one unit. Component speakers, on the other hand, separate out the woofer and tweeter into separate units that must be mounted separately from each other (usually in your car’s doors).

This gives you more flexibility in terms of placement and usually results in better sound quality, but they can be more expensive and more difficult to install. Once you’ve decided on which type of speaker you want, you’ll need to measure the space where they will go to make sure they will fit. You’ll also need to determine whether or not your car has factory speaker wire harnesses.

If it does, then installing new speakers will be relatively easy as you can just plug them into the existing harnesses. If not, then you’ll need to run new wires from your head unit to the location of the new speakers. This is generally more time consuming and difficult than using factory harnesses, so it’s something you may want to leave to a professional if possible.

Installing new car speakers is generally pretty straightforward once you have everything you need. Just remove the old speakers (if applicable), mount the new ones in their place (using screws or brackets depending on which type of speaker), connect them to any necessary wiring, replace any trim or panels that were removed during installation, and test them out!

Can I Tap into Rear Speakers for Subs?

If you’re looking to add some extra bass to your car audio system, one option is to tap into the rear speakers for subs. This can be done by connecting the positive and negative wires from the amp to the speaker wires at the back of the head unit. Keep in mind that if your head unit isn’t specifically designed for this, it could cause problems with sound quality or even damage the unit.

It’s always best to consult with a professional before making any modifications to your car audio system.

How Do I Wire My Car Speakers to My Head Unit?

If you’re looking to upgrade your car’s audio system by installing new speakers, you’ll need to know how to wire them up to your head unit. The process is actually pretty simple, but it helps to have a basic understanding of electrical circuits and wiring before getting started. Here’s a step-by-step guide to wiring your car speakers to your head unit:

1. Disconnect the negative battery terminal before beginning any work on the electrical system. 2. Remove the door panels or other trim pieces that give access to the speaker mounting locations. This will vary depending on your vehicle, so consult your owner’s manual for specific instructions.

3. Using a drill or screwdriver, remove the factory speakers from their mounts and disconnect any wiring harnesses that are attached. 4. Mount the new speakers in their respective locations and connect the positive and negative terminals to the corresponding wires from the head unit (consult your owner’s manual or look for color-coded wires). If your new speakers are 4 ohm and your head unit is only 2 ohm stable, you’ll needto wire them in parallel (positive of one speaker wired to positive of other speaker, etc.) in order for themto work properly without damagingthe head unit.

If you’re not sure about which methodto use, consult an expert installer or car audio retailer for assistance.

How Do You Tap into Car Speaker Wire?

If you want to tap into your car’s speaker wire, there are a few things you need to know. First, you need to identify the positive and negative wires. The positive wire will typically be red or black, while the negative wire will be white or green.

Once you have identified the wires, you need to use a voltmeter to test for continuity between the two wires. If there is continuity, then you can proceed with tapping into the speaker wire. To do this, first strip about 1/2 inch of insulation off of each wire using a wire stripper.

Next, twist each wire around a connector terminal and screw on the terminal clockwise until it is tight. Finally, connect the other end of each Wire Tap Connector to your speaker’s input terminals (positive to positive and negative to negative). That’s all there is to it!


If you’re looking to add some extra bass to your car audio system, then wiring up some rear speakers is a great way to do it. Here’s a quick guide on how to wire rear speakers in a car. First, you’ll need to remove the door panels or other access paneling so that you can get to the speaker wires.

Once you have access, gently pull the speaker wire through so that you can reach the other end. Next, strip away about half an inch of insulation from the end of the wire using a wire stripper tool. Then, use a pair of pliers to twist the bare wire around one of the terminals on your speaker.

Repeat this process for the other terminal and then screw or bolt the speaker back into place. Repeat this process for each of your rear speakers and then test them out by playing some music. You should now have some nice extra bass in your car audio system!
