mmmmmmmmmm its from around 2003. it birthsheeted in the range of 115x4 at 4ohms I want to say. I think. Its been a long time. I used it in my daily driver for years. I can move it pretty cheap for what it is. 160 shipped I guess will get it done. The only thing that I dont have with it is one of the end cap set screws. They are like thirty cents. Also the remote turn on lead with these has the spade connector type connetion. After time it pretty much gets stuck on there. so its got like an 8 inch section of wire that you can splice into since Ive seen too many ripped off terminals due to the same thing. I can take pics later.
