【KICKER KEY500.1｜Smart Subwoofer Amp with AI-DSP】

You’d like to add a subwoofer to boost the bass, but you want to avoid muddy sound or a situation where only the bass stands out. That’s exactly where the KICKER KEY500.1 (47KEY5001) comes in.

This model combines a mono amplifier in the 500W class with audio processor functionality. It analyzes the music signal being fed into the vehicle and corrects/adjusts the low frequencies. With factory audio, bass may be restrained due to the characteristics of the vehicle and the OEM system. The KEY500.1, however, checks the signal using KICKER’s original test tones and automatically adjusts the signal’s peaks. It replenishes bass that’s often lacking and prepares the signal needed to drive the subwoofer.

What’s interesting about this amplifier is that it doesn’t just increase the amount of bass—it’s also easier to fine-tune so the bass connects naturally with the rest of the music. Bass and kick drums that previously felt a bit thin with only the door speakers gain more depth, and even the songs you usually listen to will sound different and more enjoyable.

Even if you’re considering adding it to a factory navigation system or OEM audio, the installation details will vary depending on the input method and the vehicle’s audio signal. It’s important to adjust not only for the amplifier’s performance, but also for how power and wiring are handled, how it’s paired with the subwoofer, and how the sound ties together inside the cabin.

At LOGON, we work with you to come up with a realistic combination that won’t push the system too hard—while confirming your vehicle model, your current audio setup, and how much bass you want to enjoy. Whether you want to enjoy deep bass properly or you simply want a little more thickness in the sound of your factory audio, please tell us your preferences first.
