i have the non premium speakers too, but they work just fine. is there any possibility i have the better stock speakers? it was a dealer demo car prior to me buying it. its a 2007 compass sport with basic stereo, but i just bought it around 2 months ago. is there any way for me to check if i have the better speakers or not? just to avoid the problem with them later. if anyone can help me itd be greatly appreciated!
