GET 25 pumpin’ bass song FOR YOUR PHONE Right NOW!
It says that 300w rms is optimum for the speaker. But i have heard that it can handle up to 500 rms is this true. Shoul I get a new amp that has more Rms power? Will it make that much a difference say if i went from 250 RMS to 300-500 RMS will it be noticably louder? By the way the speaker is a JL 12" W3 4 ohm.
It will be fine if you gave it a little bit less power. There is a noticable difference between 300w and 500w but that doesn’t mean that 300w will sound bad.
Subs don’t really have a specific rms wattage that you can’t go above or below. The rms power rating is just used to give you an idea of how much power to give the sub. JL actially has a chart that shows the recommended powering values to give each sub. The link is here: http://mobile.jlaudio.com/products_subs_pages.php?page_id=35
It is also possible that the person saying that they give their sub 500w rms was using an amp that was overrated. This may lead them to believe that they were giving it 500w rms but they were actually giving it around 200-300w. Just stay within the range JL recommends and it will be fine. Good Luck!!

yes it will still sound good. If the amp is pushing more power then the sub can handle then it will sound like crap

50watts won’t affect sound very much, if any. Remember that if the ‘250′watt RMS amp is of higher quality than the ‘300′watter, the first one will sound better while actually putting out more power.
Doubling of power (if you went from 250 to 500watts RMS), in theory, adds about 3dB to the volume. This isn’t very noticeable to most people, so it’s up to you if you want to spend that much more money (500REAL watts is going to cost you at least $300).
More power, besides adding a bit more volume (not much) will make the sub sound much clearer. If this is what you want, up the power. That JL W3 can surely handle 500watts RMS, just make sure the gain is set right and does not go up more that 1/2 the way.
*Always have your gains set by a pro. Most problems with car audio originate with gains set too high (i.e system noise, blown speakers/amps).
Good Luck!

Actually, the RMS rating is the thermal rating given to a sub for continuous use without damage. Exceeding this this rating by more than 10% is not recommended.
The purpose of the gain is to match the signal volts RMS coming from the source (CD player, etc.) to the input of the amp.
Here is a guide that will help you set the gain correctly http://www.datafilehost.com/download.php?file=6d26c621
You’ll need a multi-meter (AC voltmeter), Microsoft Excel and a way to burn an audio CD from an MP3.
If you don’t have Excel, e-mail me and I’ll send you a condensed version sparky3489@yahoo.com
