I know that this has been discussed before, but I cannot get the concept straight. Power ratings on cabinets are generally listed using the acronym RMS which is a measure of the amount of power on a continuous basis the cabinet an handle. Then the term "program handling" is used which means the cabinet can take a momentary spike of up to a given wattage (usually twice as much as the RMS wattage). I purchased Fender PA speakers cabinets this weekend. On the cabinets, both terms are used but a new term is mentioned being "maximum watts". As a result, the cabs say the following: 100 watts, 200 watts progam handling, and 400 watts maximum watts. No explanaition is in the owners manual received with the cabinets and the Fender web site makes no mention of what this means. Running the cabinets in parallel (4 ohm) thru a Crest 900 amplifier producing about 300 watts at 4 ohms, will the cabinets be able to handle survive this load?
