[QUOTE="shizzzon, post: 8601166, member: 590338"] A lot of subs cannot handle more than the rating. IF you believe so, take the RMS of that subwoofer, send a FIXED amount of power to it equaling 100w less than the RMS value for 2 hours. This would take a LARGE amplifier with power source. Power ratings of subwoofers are based on many variables. Variables in which most users do not take account. By being blind to these variables, company A can be extraordinary or terrible. The same product in two different installs. For daily, typically size amplifiers for 200% of the rated rms. For long term demos, matching RMS to slightly over. For short term demos, 300% the RMS value. For burps, up to 700% the RMS value. This is what i've personally done without issue but im also aware of certain limitations as well. [/QUOTE]
