I have a Clarion ARX-4670 deck installed in my Corolla, which is a 45-watt unit. However the speakers came with the car (stock) when my stock deck's FM didn't work. Can a high-watt unit REALLY do damage to the factory speakers? I'm planning to replace them with OEM aftermarket replacements. All of the speakers operate loud & clear, it's just the two front ones deliver a very-low and nearly distorted sound when I adjust the fader control to the front.
