    I bought this amplifier and connected an ALPINE 300W RMS subwoofer and two 600W MAX speakers to it, and it handles them perfectly. I get clear sound in my car, and it doesn’t heat up easily. It’s well worth the money.

Product report

Description & Specifications

MAD A1-70.4 is a 4-channel car amplifier, designed for powerful and clear sound reproduction. It delivers 4 x 105W RMS at 2Ω and 4 x 70W RMS at 4Ω. In bridged mode, it provides up to 2 x 220W RMS at 4Ω for increased power. The frequency response from 15Hz to 22kHz covers a wide audio range. The adjustable Low Pass and High Pass filters 50Hz–4kHz offer greater control over sound shaping. The Bass EQ 0–12dB at 45Hz function allows boosting low frequencies. The specially designed A-Star cooling chassis increases the heat dissipation surface for more efficient operation. The high-level input and RCA output make it easy to integrate and expand the audio system.

Powerful and Versatile 4-Channel Performance

The MAD A1-70.4 features 4 channels and offers flexibility for different audio system configurations. It delivers 4 x 105W RMS at 2Ω and 4 x 70W RMS at 4Ω, providing stable power to the connected speakers. In bridged mode, it offers 2 x 220W RMS at 4Ω, allowing it to drive more powerful speakers or subwoofers. The damping factor above 130 contributes to better control of the speakers.

Advanced Frequency Control

The frequency response from 15Hz to 22kHz covers a wide range of sound. The adjustable Low Pass and High Pass filters 50Hz–4kHz allow precise adjustment of the playback range, while the 12dB crossover slope provides smooth frequency management. The Bass EQ 0–12dB at 45Hz function boosts the low end, delivering more dynamic and fuller bass.

Efficient Cooling and Full Connectivity

The specially designed A-Star cooling frame features an increased heat dissipation surface, helping the amplifier maintain efficient operation even at high volumes. The signal-to-noise ratio above 98dB and THD below 0.5% contribute to clear playback. The high-level input and RCA output make it easy to connect to different sources and expand the system.
