yeah well they spam it everywhere on their megaworks - gigaworks model, especially the one with 8" sub. the glue become corrosive and short-circuit the parts in the PCB. together with very hot amp many megaworks and gigaworks died very quickly. i now used 2x 80mm 12V fan to blow the backplate, still, when i put my finger into the subwoofer port i can still feel the warmth.
