Tweeters to compliment 608GTI MKII components?

[PrinceCharming]

I am getting a pair of JBL C608GTI MKII components to go in my Grand Am and I am going to drill holes and point the tweets toward the windshield so I will still have my stock mounting place open and a Kicker IX402 just sitting around so I figured I would get a couple soft dome tweets to compliment the JBL titanium tweets. The stock mounting place is on-axis, 1-inch/25mm.

My question is what tweeters would work well with this set up? I would really like to have some soft domes to go with it if they will work. I dont know how to tell which ones would work because I can't really listen to any. What would you guys recommend?

Kicker Impulse IX402:
stereo, bridged mono, or Tri-way output
frequency response 20-20,000 Hz
40 watts x 2 at 4 ohms
120 watts x 1 in bridged mode
60 watts x 2 at 2 ohms
speaker-level inputs
MOSFET power supply
0-18 dB bass boost centered at 40 Hz
0-12 dB treble boost centered at 18,000 Hz
18 dB/octave crossover switchable at 70 or 110 Hz

If you guys need any more info just tell me. Thanks.

No, just no. You need to try these speakers before you go about mucking it all up with additional tweeters.
