I remember the tweets having that.You know if I remember correctly the factory had a capacitor on it. Maybe the new ones are blowing because they don't have a capacitor.
Also, what ohm should I go with?
Nizz55, you are correct on the crossover. The factory speaker had a cap and a coil, Cap for low frequency cut off and Coil for High frequency. without those you would be running a full range audio signal to the speakers and could end up blowing them. OEM Audio+ has a drop in speaker solution for a mustang.
