The 400 watts smart car subwoofer amplifier delivers 400W RMS at 2 Ohm and 1 Ohm, providing deep, punchy bass that elevates your favorite music—from hip-hop and EDM to rock and classical.
180W RMS at 4 Ohm ensures compatibility with a wide range of subwoofers, making it easy to pair with your existing setup or upgrade to a higher-performance sub.
As a mini car subwoofer amplifier, it measures just 7.5”×4”×2” (19cm×10cm×5cm)—small enough to fit under seats, in glove boxes, or in tight trunk corners. No more bulky amplifiers taking up valuable cargo space.
Lightweight construction (not specified, but inferred from size) makes installation easy, even for DIY beginners.
THD distortion <0.1% ensures pure, undistorted audio, so you hear bass exactly as it’s meant to be—tight, clear, and free of static or noise.
Signal-to-noise ratio >95dB (A-weighted) minimizes background noise, allowing you to enjoy crisp bass even at low volumes.
Variable bass boost (0-12dB @ 45Hz) lets you adjust bass intensity to match your music taste and vehicle acoustics—crank it up for parties or dial it back for casual listening.
Variable lo-pass crossover (50Hz-200Hz, 24dB/octave) ensures seamless integration with your car’s speakers, preventing frequency overlap and optimizing sound balance.
Subsonic filter (25Hz, 24dB/octave) protects your subwoofer from damage by blocking harmful low-frequency signals that can cause distortion or overheating.
Low level sensitivity (200mV-4V) and high level sensitivity (0.5V-10V) work with most car head units, whether you have a factory stereo or an aftermarket receiver.
Supports 4 Ohm, 2 Ohm, and 1 Ohm loads, giving you flexibility to choose the subwoofer that best fits your needs.
Engineered to withstand the harsh conditions of car interiors—temperature fluctuations, vibrations, and humidity—ensuring long-lasting performance.
High-quality electronic components prevent overheating and short circuits, adding an extra layer of reliability.
Sedans often have limited trunk space, making the mini car subwoofer amplifier CAD400.1 the perfect choice. Install it under the seat or in the spare tire well to add powerful bass without sacrificing cargo room—ideal for daily commuters and urban drivers.
SUVs and crossovers have more interior space but benefit from compact amplifiers to avoid cluttering the cabin. The CAD400.1’s 400W power pairs perfectly with larger subwoofers, delivering deep bass that fills the vehicle’s spacious interior—great for family road trips or off-road adventures.
RVs and camper vans require compact, efficient audio equipment. This car subwoofer amplifier fits in small storage compartments, while its high power output enhances outdoor music sessions, campfire playlists, and in-van entertainment.
Car audio hobbyists and custom builders will appreciate the CAD400.1’s versatility. It integrates seamlessly with custom subwoofer enclosures and aftermarket head units, allowing for personalized setups that stand out at car shows or audio competitions.
Elevate your daily drive with richer bass and clearer sound. Whether you’re listening to podcasts, audiobooks, or your favorite playlist, the amplifier’s low distortion and high signal-to-noise ratio ensure an enjoyable audio experience—even during long road trips.
Yes! With dimensions of 7.5”×4”×2” (19cm×10cm×5cm), this mini car subwoofer amplifier is designed for small spaces. It fits under most car seats, in glove boxes, or in trunk side compartments—perfect for sedans, hatchbacks, and compact cars.
The CAD400.1 works with most subwoofers rated for 4 Ohm, 2 Ohm, or 1 Ohm loads. We recommend pairing it with a subwoofer that matches the amplifier’s power output (180W-400W) for optimal performance and to avoid damage.
The variable bass boost (0-12dB @ 45Hz) lets you customize bass intensity based on your music genre and vehicle acoustics. For example, you can boost bass for hip-hop or EDM, or reduce it for classical music or podcasts—giving you full control over your audio experience.
While professional installation is an option, the CAD400.1 is DIY-friendly. It comes with clear wiring instructions, and all necessary connections (GND, +12V, REM, INPUT) are labeled for easy setup. Basic knowledge of car audio wiring is helpful, but beginners can complete the installation with minimal tools.
The subsonic filter (25Hz, 24dB/octave) blocks ultra-low-frequency signals that your subwoofer can’t reproduce effectively. These signals can cause distortion, overheating, or even permanent damage to the subwoofer—so the filter ensures only safe, audible frequencies reach the speaker.
