Here we have a used amplifier removed from a 2015 GT3, this amp was tested and seemed to work fine, however it does appear to of had some water in it as you can see in the images. This is sold as is. This should fit many 13-17 991. Please confirm fitment with the vin below. The car sustained a roll over collision. We are also parting out the rest of the car so If theres anything else in particular you need otherwise please send an email so I can list it on ebay for you. Removed from Vin WP0AC2A99FS183111
