Got a pair of speakers for Hanukkah and need some advice Options

[GriffGirl]

Last night I got a pair of speakers for my car. Here are the specs:

6.5" Kenwood 1680ie

• 2-way car speakers for 6-1/2" and 6-3/4" locations (pair)
• mica-injected polypropylene woofer cone with urethane surround
• PEI semi-dome tweeter with Image Enhancer 2 baffle
• power range: 2-40 watts RMS (240 watts peak power)
• frequency response: 35-20,000 Hz
• sensitivity: 92 dB
• mounting tabs for use in 6-3/4" openings
• top-mount depth: 1-7/8"
• warranty: 1 year

My intention is for them to replace the factory speakers in the front door. I only have a 2 channel amp (powering the sub) so they will be powered by my HU, a Panasonic CQC-9901U for the time being. My g/f told me that if I wanted to return them to get something better that her feelings wouldn't be hurt cause she'd rather I have what I want than just keep it because she picked 'em out. She told me she wanted to get me a pair of Infinities (I don't know which ones) but they were like $40 more and well, we're just pretty damn broke.

So I found these online, and was wondering which ones were better:

Infinity Reference 6012i

• 2-way car speakers for 6-1/2" and 6-3/4" locations (pair)
• Plus One+ poly woofer cone with high-roll rubber surround
• rotating UniPivot silk dome tweeter
• power range: 2-60 watts RMS (180 watts peak power)
• frequency response: 53-21,000 Hz
• sensitivity: 92 dB
• Intermount III mounting system for fit in 6-3/4" openings
• top-mount depth: 1-15/16"
• warranty: 1 year

Clearly I'm on a budget, and I'm open to any other suggestions that are in the same price range. Also a 4 channel amp is a future possibility, so suggestions for those if needed would be helpful too.

Thanks!
