I just picked up some infinity 2-way 6.5" speakers today and after i put them in i got this really annoying "HISS"ing static sound from them. If i turned it up it kinda got rid of it but i dont wana ride around like that. Also when i took it for a test drive after i noticed when i got on the gas i was able to hear a whining noise from the speakers. any idea how to fix this. It is hooded up to an aftermarket pioneer head unit. I just took off the old speakers and plugged in the new ones - the wire connectors could have been tighter but they were not falling off.
