【HSA-300-31.opt | 4-Channel DSP Amplifier Adjustable via Smartphone】

HSA-300-31.opt is ideal for those who want a bit more spaciousness and clarity from their factory audio, or for those who feel that replacing only the speakers isn’t enough to fully balance the sound.

In addition to 4-channel amplifier functionality, it features DSP tuning via an iOS/Android app. Because the distance to the left and right speakers and the seating position are not uniform inside the car, playing the same audio source “as is” often leads to imbalances in the soundstage position and the cohesion of each frequency band. By tuning the system with the DSP to match the in-car environment, you can adjust the vocal position and the way sounds connect, making your everyday music easier—and more natural—to enjoy.

With an effective output of 32W × 4ch, this amplifier is also a good option if you want to increase the drive power of the front speakers or if you’d like to keep the overall system compact. Since it can be adjusted from a smartphone, it’s also well-suited for shaping the sound according to your vehicle and speaker combinations.

However, a DSP amplifier isn’t a product where the sound is determined simply by installing the unit. The final result varies depending on input method, speaker combinations, output settings, and installation method, among other factors. At LOGON, we review your vehicle model, factory system, and current audio concerns, and then work with you to plan a configuration that makes the most of the needed features.

If you’re wondering whether to replace the speakers or add a DSP amplifier, or if you want to improve the sound while keeping the usability of the factory setup, you don’t have to decide rigidly based on a single product. Let’s check your current system and sort out which parts are worth investing in and which you should try first.
