I was playing with my sub tonight. I took the sub out of the box and have it inverted mount to see what kind of differences will have . Anyway, long story short, after i finish playing, i decided to put back as it was before, and when i try to turn the ignition on,. no sound. i checked the fuse and sure enough they are blwon. What had cause them to blwon? Can anyone tell me. I was just playing with the polarity of the subs, but nothing with power cable and ground.

thanks
