Change the sound with the DSP with built-in amplifier ... I asked a professional [Installation of car audio unit]

When trying to improve a car audio system, what is worrisome is the "installation wage". In this special feature, we aim to get rid of that anxiety, and clarify the work content and cost. This time, I will explain the installation of "DSP with built-in power amplifier".

In addition, this special feature is produced by interviewing famous car audio pro shops nationwide every time. This time, we asked "Sound Freaks," a talented store in Ichinoseki City, Iwate Prefecture. I got a lot of meaningful information this time as well. By the way, what is the contents?

When you want to get the system into full swing, the "DSP with built-in power amplifier" is at its best!

First, for those who don't know, let's briefly explain what a "DSP with a built-in power amplifier" is. This is a unit that integrates a DSP (digital signal processor) for sound tuning and a power amplifier for amplifying signals, and when this is added to the system, it becomes possible to control the sound precisely. ..

By the way, when you want to get an advanced tuning function, you can replace it with a high-end domain unit if the genuine main unit can be replaced, but if the genuine main unit cannot be replaced, this " DSP with built-in power amplifier is reliable. The system can be put into full swing while keeping the genuine main unit.

Now, what kind of labor and cost will it take to install this? I asked Mr. Sato of "Sound Freaks" to tell me about that.

"First of all, the cost of fixing the main unit is almost zero when attaching it to the trunk. And the wiring work to input the music signal of the genuine main unit can be completed indoors, so it takes a lot of time and effort. Therefore, we do not charge the wages for these two tasks when you purchase the main unit.

However, it can be expensive to install under the seat. The floor surface is often uneven under the seat, so it is better to lay a board underneath and flatten it before fixing it. It will affect the sound and increase safety. If the main unit moves and the power cable is damaged, it can be dangerous. If you do this work, you will be charged about 10,000 yen (excluding tax). "

The costly points are "straightening" and "redrawing the speaker cable"!

"So, the costly point is actually in the other part. There are two main things. One is" back straight "." Back straight "means that the positive power is drawn directly from the main battery. Although it is a wiring method, we think that this method should be used when using a "DSP with a built-in power amplifier". Otherwise, in most cases, the required power cannot be secured, and the power is supplied from the back of the main unit. Even if it is a model that you can take, it is safer to "fix" it. It is soundly advantageous.

The cost will vary depending on the condition of the vehicle, but I would like you to see about 20,000 yen (excluding tax) including the material cost.

And another costly point is “speaker cable redrawing”. Using the "DSP with built-in power amplifier" has the advantage of being able to control each speaker unit individually, but in order to enjoy that advantage, it is necessary to re-wire the speaker cable. For example, if the front speakers are 2-way, you have to connect the cable directly from the "DSP with built-in power amplifier" to each of the tweeter and midwoofer.

In doing this work, I think it is better to have a new cable as well. If you change the speaker later, you will want to change the cable as well, so if you change the cable first, you can reduce the wages afterwards.

Although it is the main cost, it costs about 20,000 yen (excluding tax) excluding the cable fee. It is necessary to remove the door lining panel and the panels around the main unit, and the number of vehicles of the type that takes time to connect from the room to the inside of the door is increasing, so the work content will be unexpectedly large. "

There are other costly points ... But it's worth the cost!

"Also, if you want to embed the controller smartly, it also costs money. For example, if you use the accessory storage space of the center cluster panel to embed it, our shop is about 20,000 yen (excluding tax). If you leave it on the center console etc. without embedding it, there is no additional cost.

By the way, if you are particular about sound, there is another costly part. It is “DAP wiring work”.

When introducing a "DSP with a built-in power amplifier", the genuine main unit is usually used as the source unit, but there are many cases where this becomes a dissatisfaction factor, and in that case, it becomes desirable to use the DAP as the source unit. .. This is because the performance as a genuine main unit is often not good.

And in that case, in addition to the DAP main unit fee, the parts fee for connection will be charged. In many cases, the type of the output terminal on the DAP side and the input terminal of the "DSP with built-in power amplifier" do not match. In that case, a conversion adapter etc. will be required, and in some cases it will cost about 50,000 yen just for the parts.

As you can see, there are some costly points in introducing a “DSP with a built-in power amplifier”, and the hurdles are not low. But it's certainly cost-effective. It's easier than introducing a single DSP. If you want to improve the performance of your system, it is worth considering.
