Rockville SS10P 800W Slim Under-Seat Active Car/Truck Subwoofer, Deep Bass, Built-in Amplifier, Remote Control, Perfect for Car Audio Enthusiasts

The Rockville SS10P is a 10-inch, 800-watt (peak) slim under-seat active powered subwoofer designed for cars and trucks. With an RMS power handling of 200 watts and a peak power handling of 800 watts, it offers robust sound performance. The subwoofer has a sensitivity of 90dB, which means it can produce loud volumes without needing too much power. It operates within a frequency range of 20Hz to 180Hz, delivering deep bass tones suitable for enhancing the audio experience in vehicles with limited space, such as under the seat.

The impedance is rated at 4 ohms, ensuring it can integrate well with most car audio systems. One major strength of this subwoofer is its slim design, making it a great fit for tight spaces. Additionally, it includes a built-in amplifier and various controls like gain, bass boost, and a crossover for customized sound settings, along with a metal bass remote for easy adjustments on the go. The enclosure is made from cast aluminum, which helps dissipate heat effectively, thus maintaining performance even in confined spaces.

While the subwoofer is well-suited for compact installations, it may not deliver the same level of performance as larger, more powerful subwoofers. The sound quality, while good, might not satisfy audiophiles seeking the deepest and most precise bass. Additionally, its installation requires a wired connection, which might not be as convenient as some wireless options. The Rockville SS10P is ideal for those looking to improve their vehicle's audio system with a space-saving, under-seat subwoofer that offers good power and adjustability, though it may not meet the needs of users looking for the highest-end sound performance.

Buying Guide for the Best Car Subwoofers

Choosing the right car subwoofer can significantly enhance your in-car audio experience by providing deep, rich bass that standard speakers often can't deliver. To make an informed decision, it's important to understand the key specifications and how they relate to your needs and preferences. Here are the main specs to consider when selecting a car subwoofer.
Power HandlingPower handling refers to the amount of power a subwoofer can handle, measured in watts. This is important because it determines how loud and clear the bass will be. Subwoofers are typically divided into RMS (continuous power) and peak power (maximum power for short bursts). If you enjoy loud music or have a powerful amplifier, look for higher RMS values. For casual listening, lower RMS values will suffice.
SensitivitySensitivity measures how effectively a subwoofer converts power into sound, indicated in decibels (dB). Higher sensitivity means the subwoofer can produce more sound with less power. If you have a less powerful amplifier, a subwoofer with higher sensitivity (above 90 dB) will be more efficient. For powerful systems, sensitivity is less critical but still contributes to overall performance.
Frequency RangeThe frequency range indicates the range of sound frequencies the subwoofer can reproduce, measured in Hertz (Hz). This is important for capturing the full spectrum of bass sounds. Subwoofers with a lower minimum frequency (e.g., 20 Hz) can produce deeper bass. If you prefer a balanced sound with both deep and punchy bass, look for a subwoofer with a wide frequency range.
SizeSubwoofer size, typically measured in inches, affects both the sound quality and the physical space required in your car. Larger subwoofers (e.g., 12 inches or more) can produce deeper bass but require more space. Smaller subwoofers (e.g., 8-10 inches) are more compact and can fit in tighter spaces while still providing good bass. Choose a size that fits your car and meets your bass preferences.
ImpedanceImpedance, measured in ohms, affects how much power the subwoofer draws from the amplifier. Common values are 2 ohms, 4 ohms, and 8 ohms. Lower impedance subwoofers (e.g., 2 ohms) draw more power and can produce louder sound, but require a compatible amplifier. Higher impedance subwoofers (e.g., 8 ohms) are easier on the amplifier but may not be as loud. Match the subwoofer impedance with your amplifier for optimal performance.
Enclosure TypeThe type of enclosure (box) the subwoofer is housed in affects the sound quality. Common types are sealed, ported, and bandpass. Sealed enclosures provide tight, accurate bass and are compact. Ported enclosures offer louder, boomier bass but are larger. Bandpass enclosures produce very loud bass but can be less accurate. Choose an enclosure type based on your space constraints and bass preferences.
