Ok heres the prblem...i have poineer speakers with a cheap old sony headunit and whne turned up they sound like crap becasue of the bass in songs. I have looked on the internet and found bass blockers. I have foundout that those are just capacitors wraped in some fancy plastic cover. does anyone know how to make bass blockers ur self? I saw that radio shack sells capacitors but i dontk now what kind to get. If anyone knows. it wuldbe very appreciated!
