2016 Subaru WRX
Crutchfield Customer Review (What's this?)
These are definitely convenient. While the speaker side needed to be modified (not a huge deal as I had the correct connectors on hand) to fit my JLs, the car side plugged straight into the factory connection. If I ever sell my car I'd want to easily swap out my aftermarket stereo bits for the stock ones, something that would be annoying to do if I had more permanently wired my door speakers in. On the downside, after running these harnesses for about 18 months the right front door speaker developed an intermittent caused by too much free play that had developed over time on the Metra harness. So maybe not the best quality?
Pros: Makes install a little easier
Cons: Eventually failed and led to an intermittent
