    There are lots of good audio amplifier schematics on the web.

    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).

    a simple audio amplifier that can deliver 45 watts of power if supplied with a dc more than 12 volts say at least 14.4 volts

    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.

    The SoloX 18'"speaker is a lightweight one (100 pounds). The MTX Jackhammer is more than 3 times its weight and handles more power.

    Are these manufacturers crazy? 5,000W RMS and 6,000W RMS in a car?
    Good-bye hearing.
