I recently got a 12 jl and i put it in a sealed box etc. I ran the postive power from the battery and hooked it to the red lead on my box and made a ground to the trunk lid and put it to the ground on my box but i hear no sound or anything out of the speaker when i turn it on do i need anything else besides the box and sub? what am i doing wrong.
