Dual 10" speaker box

[jeb]

I sold my 2001 silverado and now I must sell the speaker box that fits it. The speaker box is for 2 - 10" each with .7 cu feet of air space. This fits under the back seat of an ext cab 2000 - 2006 silverado or sierra. I am asking $100 plus shipping. I am not sure what shipping will cost, so I can flex a little on the price. The box is carpeted gray. I can post pics if anyone is interested.
