Should i put in new fuses in amplifier?

The amp is most likely fried. Soundstream isn't very reliable and pushing it down to 1 ohm doesn't help that reliability either. The fuses don't have to blow for the amp to go bad. If a sub blows it doesn't short the amp, it just doesn't pull any power from it. But, I'm just confused on whether the fuses are blown or not. If the fuses are blown just replace them and try the system out. Good luck!
