External Speakers

On it's own your amp may not be delivering it's full power. Most amps that feature an external speaker jack only deliver full power when an external speaker load is present. For example: you have a 100 watt amp with a single 12" speaker and an external speaker jack.

It's a good et if it's a 100 watt amp at 4 Ohms, and your amp's internal speaker is 8 Ohms. that means you are probably only getting around 70 watts or so. But, as soon as you connect an additional 8 Ohm speaker enclosure to the amp's external speaker jack, you have your 100 watts ( 2 x 8 Ohm speakers in parallel ).

Also, some speakers sound louder than others, depending on efficiency, magnet size, and cabnet design.
Using external speakers also gives better sound dispersion, and a different tone depending on the type of speakers, the type of back (open or closed), the size of the box etc.
As always just use your ears.
