At least one of the speakers in my Mid 2010 (7,1) MacBook is blown. The amp appears to be fine as sound is clean when using headphones or external speakers. I might as well replace both speakers while I have the laptop open, but I see only a single part number listed. Does the same part work on both or is only one side available?
