ハーネスなしで車のスピーカーをラジオに配線する方法

スピーカーをヘッド ユニットに接続するためにラジオ ワイヤリング ハーネスが必要かどうか疑問に思っていて、それがない場合の対処法がわからない場合は、この記事が役に立ちます。

ハーネスなしでスピーカーを接続するために使用できる方法がいくつかありますが、それらは比較的簡単です。

カー ラジオにハーネスがない場合、または既存のハーネスまたはワイヤが損傷している場合、スピーカーを接続する最も簡単な方法はを使用することです カーラジオ ハーネス アダプター <強い>。ハーネス アダプターをラジオの背面に差し込んでから、スピーカーをラジオの色分けされたワイヤーに直接接続する必要があります。

以下の記事では、ハーネスとスピーカーをラジオに接続する際に必要なすべての要素を考慮して、ハーネスとスピーカーのあらゆる側面について詳しく説明します。

これには、ハーネスとは何か、必要ですか、ハーネスなしでスピーカーを固定できますか、ハーネスなしでスピーカーを接続する方法、そのためのさまざまな方法、色などのカーステレオ固有のワイヤー仕様、スピーカーのワイヤーゲージが含まれますそして長さ。

ワイヤーハーネスを理解する

ハーネスなしで車のスピーカーを接続しようとする場合 (難しいことではありませんが)、スピーカーやラジオなどのアフターマーケット システムであっても、手頃な価格と入手可能性から検討できます。

必要に応じて配線を追加したり構成を作成したりできるように、別のミニバージョンとして機能する小型のハーネスも入手できます。

車のスピーカーを取り付けるのにワイヤーハーネスは必要ですか?

ワイヤーハーネスを使えば、カーオーディオの配線を簡単に接続できます。ハーネスには、最大 15 本のワイヤ (標準的なカー ラジオ) を収容できます。また、車にインフォテインメント DIN またはダブル DIN ユニットが収容されている場合は、さらに多くのワイヤを収容できます。特に自動車の製造レベルでは、コンポーネントを常に手作業で相互に配線しなければならないのは大変な作業です。したがって、システム全体をサポートするこの小さなデバイスが作成されました。

ハーネスは、単純な接続タイプや圧着コネクタなどのコネクタが機能しない特殊な状況にも使用できます。

お使いのカー ステレオ システムとそのコンポーネントによっては、ハーネスなしでスピーカーを接続することはそれほど難しくありません。

ハーネスはそれほど高価ではなく、特定のハーネスが必要な場合でも比較的簡単に見つけることができることに注意してください。カー ラジオの製造元に連絡して、その供給元を尋ねることができます。また、中古車部品店に連絡して、そこで探してみることもできます。

ただし、車のスピーカーをラジオに接続するためのハーネスは必ずしも必要ではありません。

スピーカー ワイヤはカー ラジオ ハーネスの一部ですか

スピーカー ワイヤは、ハーネス接続の最大の部分です。 15 の接続ポイントを持つ標準的なカー ラジオ ハーネスは、スピーカー専用に最大 8 つの接続ポイントを提供します。

これは、通常、カー ラジオまたはアンプにはそれぞれ 2 つのスピーカー (フロントとリア) の 4 つのチャネルがあり、各チャネルにはプラスとマイナスの端子が必要なためです。

ワイヤーハーネスは機能を追加しますか?

ハーネスの役割は比較的単純です。車内に設置されている電気機器や電気部品を電気的に接続する必要があります。したがって、照明システム、ファン、エアコン、ラジオなど、車両のほとんどの要素にハーネスを使用できます。

ワイヤリング ハーネスは、特定の役割を果たす多数の個々のワイヤで構成されています。これらには、一定の電力の送信、デバイスのトリガー、情報の送信、または他のデバイスのリモート ステアリングが含まれます。

すべてのカー ステレオのコネクタ (接続タイプ) は同じですか?

すべてのカー ステレオには、ほとんどの場合、購入できるオス接続タイプとメス タイプがあります。それ以外の場合は、車に接続されます。さらに、アフターマーケットのカーステレオはすべて同じハーネスを使用できます。

どのスピーカー ワイヤがどれかを知るにはどうすればよいですか?

すべてのカー ラジオとオーディオ システムは特定の規格に合わせて色分けされているため、どのケーブルがどの色であるかがわかります。どの車やラジオを変更しようとしても、同じワイヤーには常に同じ色があります。

カーステレオワイヤーのカラーコードとは?

ほとんどの場合、カー ラジオとハーネスには、スピーカーごとに 8 本のワイヤーが付属しています。これらの色は、スピーカーを接続する際に注目したい色です。

グレー

灰色のワイヤは、右フロント スピーカーをステレオに接続するために使用されます。灰色のワイヤはプラス、灰色/黒はマイナスです。

白

白いワイヤは、左フロント スピーカーをカー ラジオに接続します。白いワイヤーはプラス、白/黒のワイヤーはマイナスです。

紫

紫色のワイヤは、右リア スピーカーをカー ラジオに接続します。紫のワイヤーはプラス、紫/黒のワイヤーはマイナスです。

緑

緑色のワイヤは、左リア スピーカーをカー ラジオに接続します。緑のワイヤーはプラス、緑/黒のワイヤーはマイナスです。

カーラジオの配線ハーネスを切断する必要がありますか?

これは、新しいラジオがあり、それをインストールする必要がある場合にのみ適用されます。車の新しいラジオまたはヘッド ユニットを購入する場合、ほとんどの場合、ハーネスが既に取り付けられており、その端にオス型の接続があります。このハーネスはおそらくかなり長い長さになります.

一部の車両では、プラグを差し込むために車のセクションまたはセクションに到達するために長いケーブル長が必要になるため、新しいラジオまたはヘッド ユニットにはこのような長いハーネスが付属しています。

新しいラジオやヘッド ユニットを購入して、ケーブルの長さが接続する必要がある場所よりも短いことを知ることほど悪いことはありません。

ただし、一部の車は、ラジオとより小さな配線領域を収容するように設計されています。 What you should do then is cut your harness and solder it back together so you do not have to cram a large amount of wiring in the small allotted area.

The soldering process is straightforward, and you do not need to be a professional to solder one or two wires. One thing to take note of is that if your harness has fuses or noise filters on them (this could be from the constant wire), then it is advised that you cut the harness beyond these points (but only for these wires) so you can keep those components fitted as they are indeed there for a reason.

How to Wire Your Car Speakers to the Radio Without a Harness

There are several ways to connect speakers with the car stereo, and they do not need any exacting knowledge or understanding of car circuitry or audio systems in general.

What factors should you consider before you connect your speakers to the radio without a harness?

Even though connecting speakers to your car radio is a pretty straightforward task, there are a handful of things you should consider so you get the job done right the first time around.

Where is the amplifier in the head unit?

It does not matter what audio system you have or where the audio system is. All audio systems at their core use the same principle. You firstly have a sound source (in our case, the car radio). The source is the device that will send the audio signal, which is of a low level to the preamp that will convert the low-level signal into a line level.

All radios will have a preamp built into them, so you do not have to worry about that. The preamp then sends the signal to a powered amplifier, where the signal is then boosted and pushed out through your speakers.

Is it a built-in amplifier?

Depending on your car audio system setup, your standard factory OEM radio may have a built-in amplifier. This is not uncommon, and then the possibility of you being able to wire your speakers to your car radio remains.

If you have replaced your car radio with the one you have purchased, make sure it has an amplifier built into it. Otherwise, you would need the additional setup to add an external amplifier to your car audio system.

Is it an external amplifier?

If your car audio system has an external amplifier, you will not be connecting your speakers to the radio, and in this case, a harness would be unnecessary.

This is because the speakers will connect directly to the terminals in the amplifier.

Since technology is ever increasing in today’s world, car manufacturers sometimes implement external amplifiers in their standard OEM factory audio setup. Depending on how the amplifier is built and designed, you would connect the wires from your speakers to it directly.

The same for aftermarket car amplifiers. What you have to do is to connect the radio outputs (RCA outputs if it was an aftermarket radio) into your amplifier and connect your speakers to your external powered amplifier by way of speaker wires and the amplifier’s high-level terminals.

Considering Speakers That Have No Harness.

Typically speakers will not come with a harness. If they are purchased as aftermarket speakers, they probably won’t even include speaker wire unless you buy them in some bundle package.

As I just mentioned, you need to know how your audio system is installed:

• Are you replacing existing speakers that are connected to your radio?

• Are you just trying to fix the sound system of a car that you know nothing about?

These are all factors you need to consider, and with speakers, you need to know if the wire runs to an external amplifier or the radio.

The only thing you will need to purchase, if necessary, is speaker wire, and depending on where they are in your car, you would need to consider the correct length and gauge, which could be a few feet.

How to Choose Car Speaker Wires?

Suppose you need to choose your speaker wire and purchase some. In that case, a wire gauge will play a role because of your amplifier’s power and distance away from the speakers (in this case, we are assuming that you are not connecting to an amplifier but rather your radio).

One thing to note is that the higher the gauge, the thinner the wire. Usually, you can be sure that your system would need between 18 and 12 gauge wires, depending on a few factors. The 18 gauge will be the thinnest wire you would need, and the 12 gauge would be the thickest and will preferably be used for the subwoofer (this is for most standard applications).

A thick wire would be recommended for speakers with low impedance levels (2 ohms) where the wire is relatively long and the power passing through it is relatively high. Hence, consider 12 to 14 gauge wire.

A thin wire would be recommended for speakers with a higher (or standard) impedance level (4 ohms) and run in a relatively short distance. In general, when the distance is less than 50 feet, you do not have to worry about increasing the wires’ thickness.

Considering your radio that has no harness.

The radio in your car should be fitted with a harness, whether it is a standard OEM factory radio or an aftermarket radio. As we said, a harness helps connect devices of a car (a radio) to other sections of the vehicle more quickly and easily, and all modern cars and aftermarket systems have them implemented for user-friendliness.

If you purchased a car stereo without a harness, you can still connect your speakers to your car radio without a harness, and we will cover the various ways below.

What Options Do You Have When Trying to Connect Your Car Speakers to Your Radio Without a Harness?

We are now assuming that you do not have an external amplifier in your car audio setup and that the speakers will run to your radio that can power the speakers. We will then also assume that you have no harness attached to your radio for some reason. When considering these factors, there are three things you can do to connect your speakers to your car radio without a harness.

Buy a Replacement Harness for Your Car Radio.

Harnesses are relatively cheap and inexpensive. You get various sizes and shapes and can most likely find one that fits your radio model if you do not have one or yours is not working correctly.

This would make things more comfortable if you later intend to purchase a new radio. Otherwise, you would have to go through the process of wiring everything up again, which would include your speakers. We will not detail how you would connect a harness in this article, but the principles used below are the same if you would like to connect a harness to your wiring system.

You Can Use a Soldering Method to Connect Your Speakers to Your Radio.

The best way to connect your speakers to your radio is by soldering your radio wire to your speakers’ wire and using heat shrink tubing to seal the wires and keep them together. I am having a great soldering experience with using a simple Iron Kit. It is available on Amazon, so check the latest price now.

This method is preferred because there is less room for error once the wires are soldered and connected, and also soldered connections are more robust. This means they won’t break or fault quickly. It is a huge hassle to remove a dash and radio just to get to one loose wire.

All you would do is strip either end of your speaker wire and radio speaker wire, placing the heat shrink tubing around the wire before soldering them together.

After you have soldered both wires, you would use a heating device (a hair dryer works well) to seal the heat shrink tubing around the soldered area of the wire.

You Can Use a Crimp Clamp to Connect Your Speakers to Your Radio.

If you do not want to play with hot temperatures, you can crimp the wires together. Just purchase Amazon terminal connectors designed to hold two wires together, creating a connection.

These little fittings that can be bought and used for car audio systems are called crimp clamps. The principle is the same as using a soldering iron to fuse the wires. However, in this case, you just need these little clamps and a crimping device to squeeze the ends down tightly.

What you would do is again strip the wires on both ends of the speaker wire and the radio speaker wire and then push each end of the wires into the crimp clamp. All you would do then is crimp both sides of the device, and the cables would be held securely in place.

As a final note, just remember in all instances when connecting your speakers to a radio, keep the colour-coded system that tells you which wire is for which speaker in mind.

結論

We determined that it was pretty straightforward to connect your speakers to your car radio without a harness because a harness is just a type of device or system that aids in connecting wires more efficiently for our purposes using a little plastic connector.

A harness is not necessary for wiring devices together. The only factor you really need to consider is what method you want to connect the speakers with the stereo.

Lastly, the two methods of connecting your car speakers to the car stereo are either soldering or using crimp clamps. Both techniques are simple and can save you money on the expert.

How to Wire Car Speakers to the Radio?

To wire car speakers to the radio, you need to strip the end of the speaker wires and connect them to the corresponding cables coming out of the stereo.

When connecting, make sure to check which wires are positive and negative.

An incorrect connection will make speakers play in the reverse polarity, which negatively affects the audio experience and can cause damaging some sensitive speaker types.

How to Wire Aftermarket Radio Without Harness?

If you install a new aftermarket radio, I do not recommend installing it without the harness.

You will need to purchase a dash kit and car stereo installation kit. These kits will help you install your new radio without damaging your car’s dash.

Once you have all of the necessary parts, follow the instructions that come with the dash kit and installation kit to install your new radio.

If you are unsure how to properly install your new radio, consult a professional installer. Improper installation can damage your car’s electrical system and void the car radio’s warranty.

How to Wire Car Speakers Without Harness?

To wire car speakers to the radio without a harness, you need to strip the end of the speaker wires and connect them to the corresponding cables coming out of the stereo.

When connecting, make sure to check which wires are positive and negative.

How to Straight Wire a Car Radio to the Battery?

To connect the radio straight to the battery, you have to put together the yellow wire with the red one and run it to the positive battery terminal.

You have to run the black (ground) wire to the negative battery terminal.

Such connection is possible and often used, especially in older cars, but the radio is more difficult to control, and it may drain your battery overnight if you forget to turn it off.

A better solution is to wire the stereo to an ignition switch so that it only has power when the car’s engine is on.
