2. Speaker wire - Wikipedia

   en.wikipedia.org/wiki/Speaker_wire

   The voltage on a speaker wire depends on amplifier power; for a 100-watt-per-channel amplifier, the voltage will be about 30 volts RMS. At such voltage, a 1% loss will occur at 0.3 ohms or more of inductive reactance. Therefore, to keep audible (up to 20,000 Hz) losses below 1%, the total inductance in the cabling must be kept below about 2 μH.

3. Vehicle audio - Wikipedia

   Mobile audio power amplifiers. Amplifiers increase the power level of audio signals. Some head units have built-in stereo amplifiers. Other car audio systems use a separate stand-alone amplifier. Every amplifier has a rated power level sometimes noted on the head unit with the built-in amplifier, or on the label of a stand-alone unit.

5. Amplifier - Wikipedia

   en.wikipedia.org/wiki/Amplifier

   When assessing rated amplifier power output, it is useful to consider the applied load, the signal type (e.g., speech or music), required power output duration (i.e., short-time or continuous), and required dynamic range (e.g., recorded or live audio). In high-powered audio applications that require long cables to the load (e.g., cinemas and ...

   en.wikipedia.org/wiki/ICEpower

   Between 2003 and 2008 the companies' product range was extended to include audio amplifier components for mobile phones, home audio (active speakers and amplifiers), car audio and home theatre (multichannel audio). In 2008 Bang & Olufsen bought out Nielsen's share in the company, making it a wholly owned subsidiary of Bang & Olufsen.
