Easy to Install once you get the Right Adapter Ring
2006 Subaru Forester
Since I upgraded my head unit, I wanted to pair it to a good set of speakers. I did my research and wanted a marine-certified speaker, just in case water got into the door panel. I have a 2006 Subaru Forester, so this speaker cannot just replace the existing OEM speakers because the existing speaker is housed in a plastic ring that is attached to the door with 3 screws, not the 4-hole pattern the speakers or the Polk Audio adapter ring that came with it. When I just fitted the speaker directly to the door, the window mechanism scraped the magnetic part of the speaker. When I called Crutchfield tech support, they said according to their information, there should be enough clearance. If not, use the adapter ring that came with the speakers. Note To Crutchfield: there is not enough clearance. I read the Subaru forums and they also agree that some adapter needs to be installed to achieve the clearance necessary. I ordered from a different aftermarket online retailer the Subaru 6.5 Universal Speaker Adapter Ring because I did not want to drill any holes into the sheetmetal of the door - this Adapter Ring matches the 3-hole pattern perfectly. I attached the Polk Audio db651 speakers to these adapter rings (these holes did not line up perfectly, but close enough), with the foam that was enclosed and attached it to the door. The window mechanism moved up and down with no problems. I buttoned-up the door trim panels and now the speakers sound great! I am thinking about replacing the rear speakers now!
Pros: Great Sound
Cons: Adapter Ring that comes with the speakers did not match the contours of my door panel. Had to purchase the correct adapter ring from a different aftermarket online retailer.
