Anyone using Chip Amps in their cars? | diyAudio

If unboosted, best you can do is bridged amps supplying some 15W into 4 ohms; of course you can use 4 such chipamps to drive 4 standard car speakers, say 2 6x9" in the back, plus 2 in-door 6" speakers for very respectable and loud 60W RMS inside your car with minimum trouble and very low cost.
TDA car-audio chip amp: purpose of output caps - Page 1
https://www.eevblog.com/forum/projects/tda-car-audio-chip-amp-purpose-of-output-caps/
Re: TDA car-audio chip amp: purpose of output caps. Yes, since the amplifiers are powered from a single-ended supply (+12V only), the output sits at 6V during "silence". No speaker likes having a constant DC current which interferes with its ability to reproduce the waveform.
DIY 4x22W car audio amplifier based on TDA7384 - Do It ...
https://scienceprog.com/diy-4x22w-car-audio-amplifier-based-on-tda7384/
TDA7384 is an AB power amplifier cased in flexiwatt25 (eagle library is included in project archive) package designed for high-end car radio applications. It allows the rail to rail output voltage swing with no need for bootstrap capacitors. I have followed the schematic in the datasheet when building a circuit.

Tales From the Chip: LM1875 Audio Amplifier : 8 Steps ...
https://www.instructables.com/Tales-From-the-Chip-LM1875-Audio-Amplifier/
The LM1875 ("eighteen-seventy-five") is a monster of a chip in a very unassuming package, and another much-loved chip in the DIY audio community. The official datasheet (PDF) claims the ability to drive 20W into 8Ω loads given +-25V, and up to 30W supplied with an extra +-5V of juice... and all at less than 1% THD.
Class D amplifiers, can a chip sound as good as a regular ...
https://audiophilestyle.com/forums/topic/31471-class-d-amplifiers-can-a-chip-sound-as-good-as-a-regular-amplifier/
Class D amplifiers--so-called 'chip amplifiers' have up to 90% efficiency, and with a good power supply can provide the best bang for the buck. The Class AB amps I see advertised are designed for automotive applications--apparently they can be blamed for the thunderous roar I hear coming from cars with big rims.

It's based on Texas Instruments' excellent TPA3250 amplifier chip, which competes well with class-D amplifiers made from discrete components. The TPA3250 can drive 8-ohm or 4-ohm speakers and is ...
What Does A Car Amplifier Do? The Only Guide You Need
https://soundcertified.com/what-does-car-amplifier-do/
A car amplifier boosts a very small electrical audio signal from the head unit to a higher voltage. It can drive loudspeakers connected with speaker wire with more power, volume, and sound clarity. Most car audio in-dash stereos have only about 15 to 18 watts available and begin to distort very badly at their maximum output.
