How about this historical article: **broken link removed**
"High Performance Audio Power Amplifiers for Music Performance and. Reproduction (Butterworth-Heinemann, 1997)".
It contains much great invention and schematic, also devices.
The power range of an amplifier has nothing to do with a radio.
Unless you are worried that a speaker that is strong enough for high power is too big and heavy for a little radio.
You can make an amplifier with thousands of watts of power. Then you can use a powerful speaker like this very powerful Jackhammer:
In the schematic, pins 1 and 2 are reversed. It won't sound good if assembled according to this diagram. It cross-references to an NTE1396 ( 11-pin SIP).
Car radio amplifiers are bridged and deliver about 18W per channel to a 4 ohm speaker at clipping with a 14.4V supply. Even the ones that advertise 200 Whats.
Philips have some car radio amp ICs with a voltage doubler for nearly 4 times more power.
Really simple! No part numbers or component types. Maybe 45 watts square wave into 2 ohms. Do you enjoy square waves? They are a bit harsh for my taste.
The jackhammer is a marketing gimmick and is a piece of sh*t compared to many subs out there. For high power, look into the SoloX 18" series 5kW RMS, 10kW burp peak.
