i got a cheap amp controler box that i wired everything threw. now the left front speaker makes a beeping sound. kind of loud but you cant hear it with the music blaring. i checked the amp and hooked up another amp i had laying around and it still did it. i tried another speaker too. when i turn the car off and the radio stays on the sound stops completely after about 2 minutes. what should i do to correct the sound? by pass the box or run it through another channel of the box? cause the conversion box is old and it might be messed up. my other side gets real fuzzy sometimes too so i think thats bad wiring but not sure. thanks for the help -nick-
