Rockville dB11 1400W Peak / 350W RMS
The Rockville dB11 is a compact 2-Ohm class-D mono amplifier delivering 350W RMS with a 1400W peak rating. It comes with a wired bass remote, a 12dB bass EQ, low-pass and subsonic filters for precise bass shaping. The small footprint helps in tight trunk spaces while maintaining strong bass performance, making it suitable for smaller cars or discreet installations that still demand impactful sub bass.
Buying Guide: Key Purchase Considerations
- Power and impedance compatibility: Match RMS power to your subwoofer’s rating and ensure the amp supports your chosen impedance (2 Ohms, 1 Ohm, or 4 Ohms). Higher power can improve headroom but requires a stable electrical system and adequate wiring.
- Class and efficiency: Class D amplifiers generally offer high efficiency and cooler operation, which is beneficial for sealed trunk spaces. Consider Class D for subwoofers when space and heat management are priorities.
- Filtering and bass control: Look for built-in low-pass filters, subsonic filters, and bass boost or a dedicated bass knob. These features help tailor the bass to your vehicle and listening preferences.
- Inputs and wiring: Verify RCA inputs and high-level inputs if you plan to connect to factory radios. Check recommended wire gauges and fuse requirements to ensure safe installation.
- Remote control options: A remote bass knob or wired sub control can simplify real-time adjustments while driving, especially in changing road conditions or music genres.
- Size and installation: Consider the physical footprint and mounting options. Some compact models fit tight trunks or under seats easily, while larger amps may require more space or a dedicated enclosure.
- Protection features: Thermal, short circuit, and overload protections help prevent damage to both the amplifier and subwoofers. Look for units with automatic protect modes and reliability reviews.
- System integration: If you have multiple amplifiers or a multi-woofer setup, evaluate whether you need a single-channel monoblock focus or a multi-channel amp with crossovers to simplify installation and tuning.
