The AEM75.4 delivers impressive power across different impedances: 75W × 4 at 4 Ohm, 120W × 4 at 2 Ohm, and 240W × 2 in bridged mode. This high-power car amplifier drives speakers and subwoofers with ease, producing loud, clear sound without distortion—even at maximum volume.
Measuring just 19cm × 5cm × 10cm, the amplifier’s compact design fits in tight spaces (e.g., under seats, in dashboards, or in trunk compartments). It’s perfect for vehicles with limited installation space, without compromising on power.
The variable Hi/Lo-pass crossover (50Hz-200Hz, 12dB/octave) lets you tailor sound to your speakers and preferences. Adjust frequencies to optimize performance for midrange speakers, tweeters, or subwoofers—ideal for custom car audio setups.
With THD distortion <0.05% (at half 4 Ohm rated power), the amplifier reproduces audio with exceptional accuracy. This minimizes sound degradation, ensuring vocals, instruments, and basslines are crisp and true to the original recording.
Featuring low level sensitivity (200mV-4V) and high level sensitivity (0.5V-10V), the amplifier is compatible with all head units—whether you have a factory stereo or an aftermarket receiver. No additional adapters are needed for seamless integration.
The 0-12dB bass boost @ 45Hz lets you enhance low-end response to match your music taste. Crank up the bass for hip-hop, EDM, or rock, or dial it back for classical, jazz, or podcast listening—total control at your fingertips.
A signal-to-noise ratio >95dB (A-weighted) eliminates background hiss and interference, delivering pure, noise-free sound. Even at high volumes, the amplifier maintains clarity, making long drives more enjoyable.
The 4-channel design supports multi-speaker setups (e.g., front/rear speakers + subwoofers), while bridged mode (240W × 2) provides extra power for subwoofers or high-performance speakers. This versatility makes it suitable for diverse audio configurations.
Constructed to withstand harsh automotive environments (temperature fluctuations, vibrations), the amplifier features a robust casing and high-quality components. It’s built to last, ensuring reliable performance for years of driving.
Supported by OEM+ODM services, the amplifier can be tailored to specific brand or project needs. Ideal for car audio retailers, installers, or manufacturers looking to create branded products.
Replace your factory amplifier with the AEM75.4 to instantly boost sound quality and volume. Perfect for vehicles with weak stock audio systems, it breathes new life into speakers and subwoofers.
For car audio enthusiasts building custom setups, the amplifier’s variable crossover, bass boost, and dual sensitivity make it easy to fine-tune sound. Pair it with component speakers, coaxial speakers, or subwoofers for a personalized system.
SUVs and MPVs often require multi-channel amplifiers to power multiple speakers (e.g., 4-door speakers + 2 rear speakers). The AEM75.4’s 4-channel design handles this with ease, delivering consistent power to all speakers.
Vans, RVs, or party buses used for mobile entertainment benefit from the amplifier’s high power and compact size. It drives sound systems for parties, road trips, or outdoor events, ensuring everyone hears clearly.
Car audio installers rely on the AEM75.4 for its reliability, versatility, and customization options. It’s a go-to choice for commercial installations, whether for individual clients or fleet vehicles.
Elevate your daily drive with premium sound—whether you’re listening to music, podcasts, or audiobooks. The amplifier’s low distortion and high clarity make even short commutes more enjoyable.
The amplifier is designed for easy installation, but we recommend professional installation for optimal results. It comes with clear wiring instructions, and its compact size simplifies mounting in tight spaces.
It works with 4 Ohm and 2 Ohm speakers (coaxial, component, or subwoofers). Ensure your speakers’ power handling matches the amplifier’s output (e.g., 75W-120W for 4/2 Ohm speakers).
Yes—bridged mode (240W × 2) is ideal for powering one or two subwoofers. It delivers higher power to enhance low-end response, perfect for bass-heavy music.
The variable bass boost (0-12dB @ 45Hz) increases low-frequency response. Use the control knob to adjust bass levels—turn it up for more punch, or leave it at 0dB for neutral sound.
A high signal-to-noise ratio (>95dB) reduces background noise (hiss, static) caused by vehicle electrical systems. This ensures clear sound even at low volumes, making it easier to hear details in music or podcasts.
