Rockville SS10P 10" 800w Slim Under-Seat Active Powered Car/Truck Subwoofer Sub,green

The Rockville SS10P 10" under-seat subwoofer is a solid choice for those looking to enhance their car or truck audio system without sacrificing space. With its slim design, it fits comfortably under most seats, making it perfect for vehicles with limited room. One of its standout features is the built-in amplifier, which provides a peak power handling of 800 watts and an RMS of 200 watts, delivering impressive bass performance that can significantly improve your audio experience.

In terms of specifications, this subwoofer covers a wide frequency range from 20Hz to 180Hz, allowing it to produce deep, rich sounds. The adjustable bass boost and crossover controls let you customize the audio to suit your preferences, while the thermal and overload protection circuits ensure safe operation. The inclusion of a remote control adds convenience, allowing you to tweak settings without having to reach under the seat.

There are a few downsides to consider. Although the subwoofer is compact, its weight of around 12 pounds can be a bit hefty for some users. Additionally, while it performs well for its size, it may not provide the same level of depth and power as larger subwoofers, especially for hardcore bass enthusiasts. The sensitivity rating, while decent, may not compete with higher-end models, potentially making it less suitable for audiophiles seeking top-tier sound quality.

Its compact 10-inch size makes it ideal for installation under a seat while still delivering impressive low-frequency impact, thanks to its powerful design and all-aluminum frame.

The dual auto turn-on options (DC-offset and signal sensing) simplify installation, enabling seamless integration with various head units.

Buying Guide for the Best Underseat Subwoofer

Choosing the right underseat subwoofer can significantly enhance your car audio experience by providing deep, rich bass without taking up much space. When selecting an underseat subwoofer, it's important to consider several key specifications to ensure you get the best fit for your needs. Understanding these specs will help you make an informed decision and find a subwoofer that complements your car's audio system and your personal preferences.
Power HandlingPower handling refers to the amount of power (measured in watts) that the subwoofer can handle without getting damaged. This is important because it determines how loud and clear the bass will be. Power handling is usually divided into RMS (continuous power) and peak power (maximum power for short bursts). For everyday use, focus on the RMS rating. If you enjoy loud music with deep bass, look for a subwoofer with higher RMS power. For moderate listening, a lower RMS rating will suffice.
Frequency ResponseFrequency response indicates the range of frequencies the subwoofer can reproduce, measured in Hertz (Hz). This is crucial because it affects the depth and clarity of the bass. A typical range for underseat subwoofers is around 20Hz to 200Hz. If you prefer very deep bass, look for a subwoofer with a lower minimum frequency. For general listening, a standard range will be adequate.
SensitivitySensitivity measures how efficiently the subwoofer converts power into sound, expressed in decibels (dB). Higher sensitivity means the subwoofer can produce more sound with less power. This is important if you have a lower-powered amplifier. If you have a powerful amplifier, sensitivity is less critical. For most users, a sensitivity rating of around 85-90dB is a good balance.
Size and DimensionsThe size and dimensions of the subwoofer are important because they determine whether it will fit under your car seat. Underseat subwoofers are designed to be compact, but sizes can still vary. Measure the available space under your seat and compare it to the subwoofer's dimensions to ensure a proper fit. If you have limited space, look for a more compact model.
ImpedanceImpedance, measured in ohms, indicates the electrical resistance of the subwoofer. This is important because it affects how the subwoofer interacts with your amplifier. Common impedance ratings are 2 ohms, 4 ohms, and 8 ohms. Make sure the subwoofer's impedance matches your amplifier's specifications for optimal performance. If you're unsure, 4 ohms is a safe and common choice.
Built-in AmplifierSome underseat subwoofers come with a built-in amplifier, which simplifies installation and ensures the subwoofer has enough power. This is important if you don't already have an external amplifier. If you prefer a straightforward setup, look for a subwoofer with a built-in amp. If you already have a high-quality external amplifier, you can opt for a subwoofer without one.
