Great thanks guys, I looked at other sites to see more pictures and the tweeters do come with different mounting setup.

So here are the dimensions of the speakers in this product:

Speaker Specifications
Speaker Size 6-1/2"
Design 2-way Component System
Tweeter Design Dome
Tweeter Composition UHF
Woofer Composition Woven Glass Fiber
Woofer Surround Rubber
Peak Power Handling 270 watts
RMS Power Handling 90 watts
Sensitivity 95 dB
Frequency Response 45 - 25000 Hz
Impedance (per voice coil) 2 ohms
Top Mount Depth 2-7/16"
Bottom-mount depth 3"
Cutout Dimensions 5-1/8"

Do you think I can make all this fit in the VX? I know I'll have to cut bigger holes for the rear speaker. How about the depth of these?

Thanks!
Michael
