For system builders who want strong output with minimal heat, the RP-800.1D provides a solid balance of power and efficiency.
Skar Audio RP-800.1DM Marine Subwoofer Amp
The RP-800.1DM brings the same 800W RMS capability at 1 ohm, but with full marine certification. It features a waterproof coating on the circuit board and rust-proof painting on the mechanical case to withstand wet conditions and salt exposure. This makes it an excellent choice for boat or pontoon installations where vibrations and humidity are constant companions. It maintains the 1,200W peak rating and the onboard bass boost options, ensuring you can dial in bass responsiveness even in challenging environments.
Key considerations include marine protection, adequate power delivery to subwoofers in confined spaces, and the ability to survive temperature fluctuations. The RP-800.1DM is built to resist corrosion and moisture while delivering dependable bass performance for marine audio systems without sacrificing efficiency.
KICKER CXA8001 Mono Class D Amp
The CXA8001 from KICKER offers a distinguished blend of power and flexibility. It provides 800W RMS into a single channel and includes a 12dB crossover, a 24dB subsonic filter, and a 6dB bass boost through KickEQ. This combination gives you precise control over low-end energy and the ability to tailor response for different music genres. Mono operation with stability down to one ohm allows for adding more subwoofers into a system if desired. The CXA8001 is a strong choice for enthusiasts seeking a rugged, feature-rich amp capable of driving larger subs with clarity.
Design emphasis centers on reliability and tunability: adjustable crossover, bass boost, and protective features that guard against short circuits and thermal overload. Aesthetically subtle, it integrates well into under-seat or trunk installations while delivering substantial bass impact.

Buying Guide: Key Considerations When Choosing an 800W Subwoofer Amp
- Power vs. efficiency: Class D designs deliver high efficiency and compact size but ensure the amp’s RMS rating matches your subwoofer’s needs to avoid clipping or distortion.
- Impedance and stability: If you plan to run multiple subs, check whether the amp is stable at 1 ohm or 2 ohms and whether it can handle the load without overheating.
- Environmental suitability: Marine models offer waterproofing and corrosion resistance, while car-oriented amps prioritize compactness and heat management for under-seat installs.
- Controls and crossovers: Built-in crossovers, subsonic filters, and bass boost options enable precise tuning without additional processors or EQ gear.
- Remote and accessibility: A wired remote bass knob or integrated remote options allow easy adjustments from the driver’s seat, improving user control during rides.
- Installation considerations: Check mounting space, heat dissipation, and required wiring kits. Some bundles include installation hardware and RCA cables for convenience.
- System compatibility: Ensure the amplifier’s power rating aligns with your subwoofer’s rating and enclosure design. A mismatch can lead to performance limitations or damage.
Across these options, the main trade-offs center on space, environment (marine vs. automotive), and the level of onboard control you need. For under-seat installations, slim, integrated models like the Rockville SS10P or RW10CA offer compact footprints with solid output. If you want a robust, tunable system with heavy bass emphasis, the Skar and KICKER models provide more adjustment potential and headroom, especially with multiple subwoofers in a larger vehicle. Marine variants protect components in saltwater settings, while entry-level bundles emphasize ease of installation. Your choice should balance space, environment, and how finely you want to shape your bass response.
