I want to make a class AB amplifier for use in cars. I don't know what chips you recommend, but I need the best sound quality.

Provide relevant typical circuit diagrams and PCB Layout requirements.

You can look at TPA321
, but the more commonly used ones now are Class D amplifiers.

There are many specifications of car AB amplifiers, which are suitable for 1-8 ohm speakers. Haha, after all, most high-quality speakers are 4 or 8 ohm. Due to voltage issues, most original car speakers are 1 ohm. Therefore, different uses have different design specifications. Here are some product tips for your reference:
1) Automotive-grade: OPA564-Q1 1.5A drive amplifier.
2) Non-automotive-grade (not recommended for installation in cars); suitable for your own play: LM675, OPA548, OPA549

I recommend two class AB amplifiers for cars. Please check whether other electrical parameters meet your needs, such as TPA6211A1-Q1 and LM48100Q-Q1.
