I had installed 3 way pinonner speakers inside my 95 F-150 In the front are the Ts-A167OR and in the back are the Ts-A6870R. When i have the bass turned up i hear a strange noise sounds like something is vibrating or making a rattling noise. Could it be that my speakers are too big or is there a loose screws somewhere? Any advice on this problem would be greatly appreciated.
The speakers are bottoming out. you need to put high-pass filters on them, at about 100Hz to help avoid this. If you want bass, consider adding a subwoofer. what you're hearing is distortion, and you're causing damage to the drivers.
