Audio Systems/Amp / Speaker requirements


I have a jukebox that has a 140 watt amp.  I picked up a woofer speaker that is rated at 700 watts.  Will my amp be able to drive the speaker?  Is there any danger of damaging the amp since there are so far apart in spec's?



No problem.

You can ignore the power rating of the speaker as those specifications are mostly witchcraft anyway.

Most important to consider is impedance matching.  The impedance rating of the speaker should be the same or higher of the amplifier.  Perfect match if for the ratings to be equal such as 8 ohms for the output of the amplifier and 8 ohm voice coil of the speaker.

Any further questions let me know.
