【KICKER LX850.1｜High-Power Monoblock Amplifier for Well-Driven Subwoofers】

You’ve added a subwoofer, but you want a bit more room in the bass. You’d like the low end to stay solid even when you turn the volume up, and to enjoy a comfortable sound in your car. That’s exactly what KICKER LX850.1 is for.

This is a monoblock power amplifier designed to deliver 850W at 1Ω, 500W at 2Ω, and 300W at 4Ω—providing ample power for a subwoofer application. It doesn’t just make the bass louder; by integrating with the front speakers and tuning it to match the volume you normally listen at, you can naturally add thickness and impact to the low end.

With a Class D design for low current draw, it also includes protection functions against heat, circuits, and voltage. Even if you’re extracting signals from factory audio systems, it supports both high-level and low-level inputs, making it easier to plan an installation that fits your vehicle’s setup. It also features a gain match LED to help you adjust gain to the input signal, as well as KickEQ+ for low-frequency tuning.

An LXRC dash remote and the LX CONTROL CENTER are included, allowing adjustment while the unit is in use. The amplifier’s center panel is reversible, and you can choose the look from 11 types of RGB LED accent colors—another distinctive touch of the LX series.

A good-sounding amplifier isn’t simply one with a high output. It’s important to achieve balance across the entire vehicle, including the subwoofer’s specifications, how you pull power and signals, the mounting location, and settings for gain and crossover. If I were doing this, I’d first confirm your current system and how you typically listen, then decide the combination based on whether the LX850.1’s power can be fully utilized.

If you’re considering adding a subwoofer or replacing an amplifier, don’t decide on a product by itself—let’s sort it out together based on your vehicle model and your current audio configuration. For those who want to change the way the bass sounds, this is an amplifier well worth considering.
