I have two of these NVX Subwoofers that I want to trade for two more 10'' subwoofers. These are dual 4 ohm subs and I'm looking for either dual 2 ohm or svc 4ohm subs and they need to handle at least 800 watts combined. If your interested just holla at me and see if we can make a deal. I will pay for the shipping to you also so thats not a biggie. Oh I almost forgot to mention that one sub has a tiny hole in the rubber surround that you can see in the pics but I used heavy duty flexible sealant and fixed it so it still sounds really good with no loss in bass.
