So I decided to do it, scrap the stock cd player out of my 99 and upgrade the HU and speakers, well i love the new HU and rear speakers which i did myself, but the componenet fronts I knew would be over my head, well when I got the car back it was just rattle rattle rattle. I ended up taking the front panels off to find they just placed the component control box in the doors with no foam or anything. I found some foam laying around the house and wrapped them in that, then placed them back in the doors, but I still get the rattle!!! What should I do, I am kinda inexperienced and the polk speakers already sent me over a comfortable budget. thanks guys!
