sub/amp rms help

[dannyt 10+ year member]

so i can know what to get and what not to get.

can an amp's rms exceed a subs recommended rms? will that damage the sub or make it better? what should be the max rms on the sub that wont damage the system?

hypothetical scenario:

a 300w rms sub into a 500w rms x 1 @ blah blah ohms.

and also, (same subs) having 1 sub running on recommended+ rms vs. having 2 subs each running below recommended rms. would the single sub come close to hitting as hard as the dual subs or maybe even harder?

while im at it.. for a single sub, is a mono amp or a 2-channel amp bridged a better choice for money and output (which one will be cheaper at the same watt output)?

THANKS

mono amp and depends on the brand of amp and the brand of sub. but the short answer is yes--it is GENERALLY ok to feed a sub more than its recommended rms. i mean to get the full power out of amp you gotta crank the volume way up as well as the gains so adjust accordingly and you will be good.
