My front right (drivers side) speaker is crackling when music is played through it. It's bad enough to enrage me to the point where I wanna bash the door where the speaker is. Before I do that, is it just a tweeter? Are they easy to replace? It's not the Bose system (doesn't say Bose on the grill or anywhere in the car anyway) and it's the one by the door handle. Please help before I go crazy!!
