Perhaps someone can help me diagnose the problem?
I can hear my sub playing music but it doesn't make any bass.
My sub was working fine a few days ago.
1) the fuse is not blown
2) the amp is receiving power
3) swapped to another amp and no bass still
My setup is stock HU to Line out convertor to amp to sub.
I am guessing either
1) sub is broken
2) line out convertor is broken
what do you guys think?
