Hi! I changed my headunit to 2-din Sony xplod recently and the space left by the stock headunit was too big so there are still some space around the new head unit. It doesnt look good in the eyes and it's been bugging me for a while. I dont know what to fill it in. Also, I whenever i step on the accelerator and the headunit is on, there's always a whistling noise. I think it needs an audio capacitor but i dont know which one. I dont know much about cars so i dont know which ones to get. There are like 1 Farad Capacitor, then there's 2, then 3, etc. Please help? Thanks!
