Alpine iDA-X001 w/ Aftermarket Speakers

[Synomenon]

Ok, so I'm going to put an Alpine iDA-X001 into my other car and also replace the stock speakers.

Here are the specs. for the Alpine iDA-X001:
Power Requirement: 14.4V DC
Power Output: 18W RMS x 4
- Power measured at 4 ohms and =< 1% THD+N
- S/N: 80dBA (reference: 1W into 4 ohms)
Max. Pre-Output Voltage: 2V/10 K ohms

These are the speakers I'm getting to replace the stock front speakers (the car does not have factory tweeters):

These speakers will replace the stock rear speakers:

I've asked around and people tell me that the iDA-X001 will run these speakers just fine.

Is there anything else I need? I'll be using the stock speaker wiring. I don't want to spend more than $500. I've spent ~$400 already for the iDA-X001 plus the speaker sets.

It will probably sound good just powering off the deck but to really make those speakers sing I suggest a 4 channel amp with about 40-50w rms per channel output. If you can squeeze another $100 into your budget this is do-able. But if money is really tight get a 2 channel amp to power the front components and run the rears off the deck. The output on components is like night and day when you give them a little more power from an external amp.
