Answer 1

Well it really does depend on the brand. But a 500 watt woofer with a good box might produce 390db or over probley...thats a guess i really dont know for sure.

Answer 2

It depends on a lot of things.

500 watts peak or RMS?

Room size?

Normal listening or test tones?

If it's a decent sub you can expect around 100db-105db, maybe more but there are a lot of details left out from your description.
