Okay, the NX30 tweeters are installed and they are a great improvement over the Bose 2" speakers. I listen to a pretty wide range of music from acoustic guitar, to drum & bass, to Coltrane, to Moby.
You can actually here the highs in electronic music and the strumming in an acoustic guitar performance. I am very pleased with the results. I actually turn down the treble -1 on some songs since you do get a lot more sound in the upper range.
For my installation, I pretty much did everything that Mr. Wiggles did in the "Great Idea Shared" thread. Click here
Excellent thread. Oldie but goodie.
In a nutshell, I pulled out the stock 2" speaker, took off the filter and then soldered it to the new NX30 tweeter. The NX30 tweeters are a little bigger than the stock mounts so I heated up the sail mount with a hair dryer to help stretch it out a bit so the tweeter could squeeze in the mount a little better. It's definitely a pressure fit. I then made a simple bracket to hold in the tweeter using the same 2 screws that held in the Bose speakers.
It's quite simple really. The car looks exactly the same as before and sounds much better. No cutting or drilling into the car at all. The Bose system should have had these tweeters from the beginning. Very happy with the results and $109 well spent. Now I need to add some bottom end to the sound.
Here's a picture of the Bose speaker and the filter you need to clip and solder to the new tweeters.
