Its worth spending that little bit extra on speakers to get slightly better quality ones. I have a set of Infinity 6x9s in the back of my disco which I paid £60 for (should've been £85) and can honestly say I would never bother with cheapo ones again. The sound quality is really good, and they used to be in my uno for two years in which time I went trough two sets of cheap 4" sets in the front........
