I just bought my 2008 Lancer GTS a couple weeks ago. I've already had to replace the amplifier in it which leads me to believe that the stock sub is blown as well. It hasn't worked since I bought the car but I've heard a little feedback from it here and there. I'm assuming that it is blown because there is no sound, but is there a way for me to better diagnose this issue? I'm tempted to buy a new sub just to get it taken care of but before I do I want to do everything I can to avoid spending more money. Does anyone have any suggestions? Let me know! Thanks for your times guys!
