First and foremost, these speakers sound awesome. The quality is so much better than the 20 watt OEM speakers that these replaced. However, I will say, that make sure that you don't damage the OEM speaker grill while removing, as the Blaupunkt grill is way to large to fit, and because of the curvature of the door don't really mount flush. Also, the package includes tweeters, however, at least on my Jetta, the only tweeter are on the back deck. Odd that these are slated for the front, and have a connection for the tweeters, but the 66.3 that are slated for the back, only have one usable connection even though that's where the tweeters are, at least on my "Burrito Jetta"
Great sound for the price. Easy install with the included "FREE" adapters and instructions.
Although, it might "Fit" some Jetta models, not that great of a fit on mine if you want to use the Blaupunkt grill.
