I have a Dual headunit and pioneer speakers all around, and recently at about 30 and higher the music gets really distorted, almost to the point of it being static, 46 is the highest on my headunit so 30 is somewhat loud. I used to play my unit at 40+ occasionally and it would play perfect but this is a recent problem, any guesses to what it could be? I may try to check and see if any wires are touching each other tomorrow but they shouldnt be, I wrapped all of them, the speakers never had a burning smell or anything and the speakers are 4 years old, the head unit is about 2 years old, I hope its not time for new speakers...
