Rockville dB45 3200W 4-Channel Car Amplifier | High-Speed MOSFET, Adjustable Crossover & Sub Control

Powerful car audio amplification

The Rockville dB45 is a 3200W peak, 800W RMS four-channel amplifier built to drive subwoofers and speakers with authority. When wired for 2 ohms, it delivers up to 200W per channel; at 4 ohms, you get about 135W per channel. These numbers create a robust foundation for any car audio upgrade while keeping reliability in focus.

Flexible tuning for your sound

Take control of your sound with a fully adjustable 12dB per octave crossover, a dedicated subsonic filter, and a 12dB bass equalizer. These tools help you tailor the bass response, tighten the punch, and maintain vocal clarity across tracks from rock to jazz.

• 12 dB per octave crossover lets you separate frequencies and optimize bass, mids, and highs.
• Subsonic filter minimizes low frequency energy that can cause woofer fatigue at high volume.
• Bass equalizer offers precise tonal shaping for deeper, controlled low end.

Efficient power and intelligent protection

The dB45 uses a high speed MOSFET power supply for efficient conversion and stable voltage delivery. IC controlled protection guards against overheating, voltage fluctuations, and short circuits so you can enjoy longer listening sessions with confidence.

• High speed MOSFET design supports stable performance under demanding loads.
• Thermal and electrical protections help safeguard the amp and speakers.
• LED illuminated Rockville logo provides a stylish indicator in low light.

Design and installation flexibility

A practical setup includes a remote dashboard sub control for on the fly bass adjustments, simple RCA input output connections, and a robust chassis designed for easy mounting in most vehicles. The dB45 is engineered for straightforward integration with aftermarket subs and amps.

• Remote sub control lets you tweak bass from the dash without reaching behind the seat.
• RCA input and output connections support flexible head unit and sub integration.
• LED logo and clean layout aid in quick setup and easy diagnostics.

Real world use cases and outcomes

Picture a weekend road trip with a stronger, cleaner sub bass and a more defined overall sound. Or a daily commute where bass remains tight without masking vocal clarity in the mid and high ranges. The Rockville dB45 is designed to support a capable car audio system and to grow with your listening preferences.
