【Installation Labor Fee for Brought-in Subwoofer Amplifier｜Car Audio Installation】

You want to install your own subwoofer in your car, but you don’t know how to connect the amplifier or wiring. You also want to make the equipment you bought online work properly—naturally and neatly. This is the installation service for a brought-in subwoofer amplifier for people like you.

We check the work details according to your vehicle and audio system, such as the amplifier power wiring, signal takeoff, and connection to the subwoofer. Since the connection method changes depending on whether you have a factory navigation system, a display audio system, or an existing amplifier, it’s important to evaluate not only the brought-in equipment, but also your current car’s entire system.

Especially for amplifier installation, safety and finish can vary depending on how the power is sourced and how the wiring is handled. It’s not enough to just make sound. You’ll be more likely to be satisfied if you actually listen and confirm things like whether the subwoofer blends naturally with the front speakers and whether the bass is not overly dominant.

For brought-in items, the対応 may vary depending on the brand and model, included accessories, and your vehicle specifications. After checking the actual vehicle and the equipment, we will advise whether it can be installed, whether additional parts are needed, and how much adjustment is possible. Don’t decide based only on email—let’s check together first.
