the other day i went to get inside my car (it was raining) an when i got in my subs started making this poping sound so i turned my car off went to check everything the amp smelled like it was burning up so i unplugged everything an took it inside for the night this mourning i hooked it back up an it was working fine drove around the block an it cut out again with more burning smell i have no idea what could cause it to act like this
