Tach zusammen,
bin ich beim stöbern bei NXP.com (ehemals Philips) drüber gestolpert:

The TDF8591TH is a high-efficiency class-D audio power amplifier with low power dissipation for application in car audio systems. The typical output power is 2 x 100 W into 4 Ohm.
The TDF8591TH is available in an HSOP24 power package with a small internal heat sink. Depending on the supply voltage and load conditions, a small or even no external heat sink is required. The amplifier operates over a wide supply voltage range from +-14 V to +-29 V and consumes a low quiescent current.
* Zero dead time switching
* Advanced output current protection
* No DC offset induced pop noise at mode transitions
* High efficiency
* Supply voltage from +-14 V to +-29 V
* Low quiescent current
* Usable as a stereo Single-Ended (SE) amplifier or as a mono amplifier in Bridge-Tied Load (BTL)
* Fixed gain of 26 dB in SE and 32 dB in BTL
* High BTL output power: 310 W into 4 Ohm
* Suitable for speakers in the 2 Ohm to 8 Ohm range
* High supply voltage ripple rejection
* Internal oscillator or synchronized to an external clock
* Full short-circuit proof outputs across load and to supply lines
* Thermal foldback and thermal protection
* AEC-Q100 qualified

Wenn man den herbekommen würde, wäre es sicher ein Kandidat für ne Mikro-Endstufe mit ordentlich Bumms...
