is $250 a good offer or too low? just for the sub itself, no enclosure...

also do you guys recommend a sealed or ported box for the g35 coupe? i listen to lot of hiphop/rap/trance/freestyle stuff, so what do you recommend?

 

$250 sounds low to me. If I had just bought something for $500, I'm not going to turnaround and sell it for half.

Regardless, I'd never even consider buying a used subwoofer unless I knew the person. It could very easily be blown or in some other way broken.
