I dont know if this is fixable or what even caused it. This thing has ran strong for me for 5 years and then just went today when i wasnt even thumpin. Every time i turn the power on to my HU the sub pops out and stays there, when i turn the HU off it goes back to place. whats the deal? I know its blown but i would like to know what caused it, maybe because its just old and tired? What does this problem usually mean?
