Well I am second quessing myself now too. I installed the dirvers side component last night with the x-over and it sounds almost tin canny, and not as good as the factory speaker on the passenger side. I have researched another forum and it was stated to not install the cross over with the infinity amp due to it all ready being crossed over??
What is currently happening is that high frequencies only are coming out from the infinity amp. You now added a crossover to that audio signal which is additionally reducing level and frequencies, adding phase distortion and then going to the new tweeter you added and will make it sound like a tin can like you are observing.

I just want to start off saying thanks for all the positive feedback. I had searched these speakers through crutchfield and didnt think anything of not being able to handle the power due to the factory infinity amp. Here are the speakers stats:
component speaker system includes 2 woofers, 2 tweeters, and 2 crossovers
5-1/4" Plus One+ Injection-Molded Polypropylene (IMPP) woofer with hi-roll rubber surround
1" edge-driven textile dome tweeter
Starfish™ mounting brackets for easier tweeter installation in factory locations
2-way external crossover network (18 dB/octave, 3,500 Hz high- and low-pass)
2-ohm impedance for extra power (compatible with virtually all factory or aftermarket car stereos)
tweeter adjustment circuits (0, -3 dB)
power range: 2-75 watts RMS (225 watts peak power)
frequency response: 67-21,000 Hz
sensitivity: 92 dB
top-mount depth: 2-1/4"
My question I am confused about where your coming from is, are you saying to hook the x-overs before going threw the factory amp? Or after the amp? I currently hooked the drivers side up after the amp, and from the cross over installed the woofer and tweeter.
thanks

The speakers you have are fine. A cross over is only needed if the wires connecting to the speakers are at a full bandwidth audio frequency of 20Hz-20Khz.....If you have the Infinity amp, then that is NOT the case.

Took the x-over out on the driver's side and installed the passenger side as instructed. They sound really good now! Thanks for all the input. Now waiting on some 6.5" Infinity reference speakers for the sound bar now. Also been looking around for all in one DVD/recievers for the headunit. Its like an adiction now.. haha

The reason is that the Infinity amp has 8 channels of output and each speaker in the system is fed by a single dedicated amp channel. On the non-Infinity systems, there are 4 channels from the radio connected to 6 speakers, which means that the front woofer and front tweeter both share a single amplified channel. Due to that, the single channel feeding the 2 front speakers can not limit the frequencies that go to each speaker so a x-over must be inserted to handle that task. So with the non-Infinity JKs you need the x-over.

The tweeters just pop out and you can either use new hardware, or I just used the factory grill to keep it a factory look.

For the drivers side just pop off the plastics under the steering wheel and lower dash above pedals, and unbolt approx. 8 bolts. Enough to pull the speaker box out. THere are two gold bolts on the speaker box, and one underneath, and shimmy her out.
