h/k sub question/problem.

[SL Blak Soldier]

so my h/k sub makes weird noises sometimes, not all the times. it sounds like a crackling or a popping. are mine subs toast? or is it just like a wiring problem? they still hit like normal they just make crackling/popping sound.



..yeah yeah i know i should upgrade but i want to buy other stuff before i get my stereo stuff done.
