EDGE 900w Subwoofer with built-in Amp. I bought this last November for £90 at sale price. I had it in my car for about 3 weeks and got a new car, have decided not to install in to the new car as my head unit does not have any audio outputs. Sub/Amp also comes with wires but these are not included in the price as they were only a cheap set bought from What, therefore have left them on as a gwg
