I have an 18" Eclipse Titanium Subwoofer for sale. I bought this about 9 months ago and now I am selling it so that I can paint my car. I really hate to do this but its come down to it. This sub is 5000 watts peak and 2500 ( i think ) rms. You need to have a huge amp or a couple to power this thing. Ill add the specs of it later but Im asking $650 which is half of what I paid this is a steal. Ill try to add pics later. If you're interested, call me at 608-658-3750 im in Madison, WI and am willing to deliver to serious buyers within a 150 mi radius. (Chicago, Milwaukee, Madison)
