【KICKER 46CXA660.5 5-Channel Power Amplifier｜Boost the Front, Rear, and Subwoofer in One Unit】

I want the sound from my factory audio to have a bit more body. I’d like to drive the front and rear speakers properly, and also add a subwoofer.

That’s where the easy-to-use KICKER 5-channel power amplifier 46CXA660.5 comes in.

With full-range output across 4 channels, plus a dedicated channel for the subwoofer, you can drive the entire in-car speaker system with just one unit. Compared with installing multiple amplifiers, it’s easier to keep the setup organized, and it’s a model worth considering if you want to step up your audio system within limited space.

Bring out solid bass while supporting the entire music

The full-range channels use a Class A/B design, while the subwoofer channel uses a Class D design. Channels for vocals and instrument sounds are separated from the channel handling low frequencies, with the necessary output allocated to each.

Even when you replace the front speakers, it becomes easier to take advantage of the speakers’ capabilities, adding thickness and headroom to the sound. By pairing a subwoofer, you can aim not just to make the bass louder, but to deliver bass in a way that supports the overall foundation of the music.

Because it features a built-in crossover, a subsonic filter, and KickEQ™ for adjusting the low end, you can tailor the system according to how you combine your speakers and subwoofer. If you use the optional remote bass controller, you can also adjust the bass level from the driver’s seat.

Designed to make adding to factory audio easier

When adding an amplifier to a factory navigation system or factory audio, you may be concerned about how to tap the output signal and how the input levels are handled.

In addition to low-level inputs, the 46CXA660.5 supports high-level inputs and includes FIT+™, which can accept input signals up to 40V. It’s a spec that’s easy to consider if you want to add an external amplifier while taking advantage of the vehicle’s factory system.

However, the actual connection method and required parts vary depending on the vehicle model, the specifications of the factory head unit, and the equipment already installed. It’s not as simple as “add an amp and the sound gets better”—the final result depends on everything from how you source power, wiring processing, speaker combinations, to the last adjustments.

At LOGON, we consider whether it’s better to consolidate everything with one unit or use a different configuration, while checking how the vehicle will be used and your current system. If it were me, I’d first confirm your current audio complaints and what equipment you want to add in the future, then decide how to use the amplifier.

For those who want more headroom when turning up the volume, for those who want balanced output from the front, rear, and subwoofer, and for those who want to organize the system in limited space—this 5-channel amplifier has plenty of use cases. Please consult us about a configuration that fits your vehicle model and existing system without forcing anything.
