For the price, and given the limited options available in Hong Kong, I am pleased. A couple of notes:

1) the tweeter is too large to snap into the OEM housing. However, you may wish to play with the direction before mounting the tweeter anyway. I modified the housing to change the direction of the tweeters so that they face away from me and more towards the windshield. I then used silicone caulk to hold the tweeter in place.

2) I did use silicone caulk to seal the mid-speaker to the front of the speaker mount that I created.

3) finally, the frequency range of the speakers on the low side is 90 hz. Not particularly low so I'm probably weak in the mid-bass area but I don't really notice it. For discriminating listeners however, this may be a concern.
