【AT-HLC150｜High-Quality Line Converter That Converts the OEM Navigation’s Speaker Output to Line Output】

You may want to add an external amplifier or subwoofer to a factory car navigation system or to a head unit that does not have line outputs such as RCA. That’s exactly where AT-HLC150 from Accessory helps.

Because it can convert your head unit’s speaker output into line output, you can keep your OEM navigation unit and expand your setup by combining it with an aftermarket amplifier and more. It’s ideal for those who want to establish a solid audio foundation that fits your current in-car environment without drastically changing the volume or day-to-day usability.

In addition, since it features an ACC power delay function and a remote output, it becomes easier to think about synchronizing with an external amplifier even when your head unit lacks a remote output. It’s an important component for organizing your overall system when you want to improve sound little by little from the factory setup, or when you’re considering a configuration that adds an amplifier.

Another highlight is that it uses high-quality audio design and a robust metal body while being compact for easier installation. However, the actual connection method and where you install it will vary depending on the vehicle model, the specifications of your OEM navigation, and the amplifier you plan to add. Even with the same product, the final result can differ depending on how you tap the signal and handle the wiring, so if it were me, I’d confirm the actual vehicle and the entire system before deciding on the combination.

If you want to add an external amplifier while making the most of your OEM navigation, or if you want to connect a subwoofer properly, please tell me your vehicle model, your current audio configuration, and what you’d like to do in the future. Let’s work together to design a practical system that fits your usage—without forcing a drastic change.
