the amp's continuous output power will exceed the sub's capabilities. you have the potential to permanently damage the sub.
try to find an amp that's rated close to 200 Wrms for this sub. yours is rated for 300 Wrms.

Having a higher rated RMS value on the AMP is much better than having an amp that is matched or rated lower. Its the distortion that does more damage to a sub more so than one that is over powered.
My sub is rated at 300rms, my amp pushes 400rms....sounds great!

while there is a modicum of truth in this statement -- it's really 
and is bad advice.
exceeding the speaker's rated power is always risky to your equipment. i will sometimes suggest doing this, but you should strive to keep the amp's rated continuous (rms) power within a window of approximately 125% of the rated continuous power of the speakers. this will generally keep you within the manufacturer's factor of safety, and will allow for greater dynamic headroom.
in this case though, he is exceeding the rated power of his sub by over 50%.
i highly do NOT recommend this pairing.
regarding too little power blowing speakers: again,
if that were true, any time ANY of us listened to our systems at anything OTHER than full volume, we'd be blowing speakers. it just isn't true.
check this link out for the reasons behind this urban legend: http://www.bcae1.com/2ltlpwr.htm
and Tugz_S2K, in your case -- if you're talking about the JL 12W3v2 -- it does NOT have a continous max rated continuous power of 300 Wrms. that's JL's recommended power.
look CLOSELY at this document: http://www.jlaudio.com/subwoofers/pdfs/12W3v2_MAN.pdf
you will see that your sub actually has a MAX rated continous power of 600 Wrms. so, you are actually running your sub at 400 Wrms which is FAR below ( 2/3rds) the subs max continuous power.
edit:
this isn't an attack, but i don't want someone out there blowing speakers due to some unintentionally bad advice.
and yes, i know you mentioned distortion from too little power... but honestly -- contrary to popular belief, excessive power kills speakers, not distortion.
