Wired my amp and sub in my truck and sound was working just fine on accessory?

Question

then when i started my truck the sound shut off and now only the bass plays. The bass plays just fine but my speakers dont put out and voice. When i start up the truck my speakers make a buzzing sound for a second then emit no sound whatsoever im lost is there anyone who knows how to fix this?

Answer 1

i'm not sure but it might be that a negative speaker wire is touching a positive wire or some wire is touching a metal part of the car i've had this happen so you can check that or take it to an audio installer he might be able to figure it out
