- Amplifier chip
Many Car DVD has built-in amplifier nowadays, including Eonon and this Non-brand unit. But are they using the same amplifier chip?

We use TDA7850 amplifier chip:
High output power:4 x 40W/4Ω max.
Signal to Noise Ratio: 80 dB
Total Harmonic Distortion:≤0.025 percentage
Non-brand unit:
It has TDA7384 chip:
High output High output power:4 x 40W/4Ωmax.
Signal to Noise Ratio: 65 dB
Total Harmonic Distortion:≤0.04 percentage
Although they’re both from ST company, but the performance of TDA7384 is much lower than our TDA7850
