is my amp to weak?

[Rockguy475 10+ year member]

i have a 12 in.W7 and a 500/1 JL audio amp for it... the amp has a 500 RMS or thats what it says on the box but i have heard that JL under rates its amps RMS and that they normally put out about 50-100 more then what the box says... meaning mine would put out anywhere from 550-600 watts RMS... my sub has a 750 RMS.. i know that my amp isnt as great as the 1000/1 model but i have a ported box so the sound should be loud right??? basicly what im asking is, is it ok for me to use the 500/1 JL amp for my 12in W7

It is ok for you to use the 500/1 on the W7, but you really are underpowering it. I say hook it up and see how you like it.

I have a 12W7 running off a 1000/1 in a sealed box because im limited on space, and it sounds great.

The RMS on the W7's is underrated.The 12's could take a 1000/1 all day.

is it bad to under power a sub? like will i do damage to it.. on the JL site it says damage will not be done if under powered but the sound may not be as good

No...

you can damage your sub is you have a small amp for the sub and you turn up the gains to the top and clip the amp... a clipped signal can damage your sub.
