Multiply the number of volts by the number of ampstodetermine how many watts the

**speaker**uses. Ifthe**speaker**operates at 110 VAC, at 2 amps, the**speaker's**wattage is 220 watts.

Also asked, what is speaker output power?

Match the **power** requirements of**speakers**with the **output power** of the amplifier orreceiver.**Speakers** require more or less **power** thanothers— loudspeaker sensitivity is expressed in decibels,which isa measure of how much sound **output** is produced withaspecified amount of amplifier **power**.

**amplifier can**only deliver a maximum of50watts of

**power**, then the

**amplifier can**stillonlydeliver a maximum of 50 watts of

**power**irrespective ofthe

**power**rating (capacity) of the

**speakers**.The

**power**rating of a

**speaker**is normally indicatingthemaximum

**power**you

**can**safely drive the

**speaker**with.

Secondly, how many watts is a 4 ohm speaker?

200 watts
