Whats it worth?

I got a 15'' Kicker CVR laying around inside a ported box for 2 15's. A friend of mine is interested in trading out some work for it but im not sure how much its worth. I got the speaker with a blazer i bought 3 years ago and ive never done anything with it.

do u have one speaker and a box that will house two speakers, or what? dont really understand

Yea, i had 2 in a box but used 1 in another truck.

If there in good condition $75 for both.
