did you sell the roof tent? if not perhaps add that to the ad and include it in the price also you can have your classified ad with accept offers too and set it to what you will and won't accept :)
only had mine a short while n used it twice n the internal speaker went! luckily i had some external speakers spare to plug in, can now hear it most of the time over the road noise and my music!! :0
I got some off ebay and they were too big for the holes so after me doing much bashing with a hammer to not much avail, @ngserv came along with the drill n made the holes slightly bigger :)
I've got em fitted n they are bloody heavy to do on your own (5ft 4" female) but I did em, but I haven't wired the heat bit on the seat in as I am crap at lectrics and the leccy bit on the drivers seat is straight onto the battery with an inline fuse fitted! :)
