【HSA-300D｜4-Channel DSP Amplifier Adjustable via Smartphone】

The HSA-300D is a great fit if you want a bit more spaciousness and cohesion in the sound of your factory audio, or if you’d like to fine-tune the sound in your vehicle to match after replacing your speakers.

In addition to its 4-channel amplifier function, it includes a DSP function that allows you to adjust the sound using iOS/Android apps. Because you can change settings using a smartphone, it’s easy to balance the sound according to the music you listen to and your preferences.

Maximum output is 50W×4, with rated output of 30W×4. This specification makes it a good option if you want to drive the factory system a little more firmly, or if you want to bring out the performance of your speakers.

However, with a DSP amplifier, the sound isn’t determined simply by installing the unit. It’s important to adjust while confirming the factory audio setup in your vehicle, compatibility with your speakers, the installation method, and how it sounds inside the cabin. Even with the same product, the final result will vary depending on how you combine it and how far you tailor it to your vehicle.

At LOGON, we guide you after checking your vehicle model and current audio configuration, the music you usually listen to, and the direction of sound you’re aiming for—including whether it makes sense to use the HSA-300D. If you’d like to think together about a setup that lets you enjoy music comfortably after installation (instead of deciding only the product first), please feel free to contact us.
