500w not enough for a JL Audio 10w7?

[DDDD]

I was talking to a friend today who worked at a custom audio shop for a few years and he said that my JL Audio 500.1 would underpower my single JL Audio 10w7.

This might be a stupid question but I'm wondering what this means. If the sub runs at 500w which is dead center of the JL Audio manufactureres spectrum wattage chart, won't that be as far as I want to push it? Also I don't plan on playing this sub at max volume all the time, which is what I would imagine 500W to be. At low volume the sub does not draw 500W correct?

He also said that even if I got the 1000.1 to power the sub, my car would not be able to handle it. I drive a 93 Honda Accord EX Wagon and I am unsure of all the specs of the alternator etc. Also I haven't upgraded any stock wiring.

Thanks for helping.

He might not think that it is loud enough with "only" 500 watts. Opinion only. I know people that are perfectly happy with a 500/1 on their 10W7.

500/1 is perfect for it just like u said its right in JL's recommendations. And if u port it then that would increase output greatly with less power.

i'd put 750 watts on a 10w7, but that's just me
