Why Choose Kicker 51HS8 Powered Subwoofer?
Powerful Bass in a Compact Design
Kicker designed the Hideaway™ compact powered subwoofer with versatility in mind, aiming to deliver powerful bass performance in tight spaces.

Its built-in 150-watt RMS amplifier provides robust, deep bass that enhances any music genre, making it an ideal addition to your car audio system.
Impressive Performance in a Compact Package
The 8" woofer in the Hideaway™ delivers impressive low-end bass that will elevate your listening experience, especially when mounted inside the passenger compartment. With the included remote control bass knob, adjusting the bass level to suit your music is quick and easy. For simple installation, Kicker provides nylon straps with Velcro® fasteners for secure mounting, along with a quick-disconnect harness featuring power and signal wiring to streamline the setup process.
Class-D Amplifier
With its Class-D amplifier, the Kicker HS8 can handle a power output of 150 Watts RMS. The powered subwoofer has a frequency response of 25 to 120 Hz, allowing it to deliver an extensive low-frequency performance. The subwoofer also comes with a polypropylene cone and a rubber surround to ensure accurate bass output while being driven at high volume levels for extended periods.
Frequently Asked Questions (FAQ)
- • Will this fit under my seat?
Fitment depends on your vehicle's available clearance beneath the seat. Measure the installation space and compare it with the product dimensions before purchasing.
- • Why won't the powered subwoofer turn on?
A blown fuse, poor ground connection, or missing remote turn-on signal is the most common cause. Check all power, ground, and remote wiring before troubleshooting the unit itself.
- • Can I connect this to my factory stereo?
Yes. It is compatible with many factory head units using high-level speaker inputs or a line output converter when necessary.
- • Why is there power but no bass output?
This is often caused by incorrect crossover settings, loose input connections, or the source unit not sending a bass signal. Verify all wiring and audio settings before assuming the subwoofer is faulty.
- • Why does the bass sound weak?
Weak bass is usually caused by improper gain, crossover, or phase adjustments. Fine-tuning these settings and checking the installation location can significantly improve performance.
- • Why does it shut off after playing for a while?
The built-in amplifier may enter protection mode because of overheating or a wiring issue. Ensure the unit has adequate ventilation and inspect the electrical connections.
- • Does it require an external amplifier?
No. It has a built-in amplifier, so no separate external amplifier is needed for normal operation.
- • Why do I hear alternator whine through the subwoofer?
Alternator noise is commonly caused by poor grounding or signal interference. Improving the ground connection and routing RCA or signal cables away from power wires usually resolves the issue.
- • Can I adjust the bass level from the driver's seat?
Yes, if the powered subwoofer supports an optional remote bass control. A remote level control allows quick bass adjustments without accessing the amplifier.
- • Can I upgrade the rest of my sound system later?
Yes. The powered subwoofer can be combined with upgraded speakers and amplifiers to create a more balanced and powerful audio system.

Bought it for my Tundra. I like that it is not overpowering with my speakers. The enclosure also just fits right in.
