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.

you need an amp for those speakers probably a 4-channel if you're using all of them.

the Alpine MRP-F450 would help them out. hopefully you can find them cheaper on eBay.

The iDA-X001 should be able to run those infinity speakers just fine. 18W RMS is what most headunits can output anyway. However, by not using an external amplifier you won't be able to turn to the volume up super loud since the head unit is not strong enough. If you don't listen to music loudly then it should be fine. An external amp helps your speakers perform at their full potential and makes everything clearer too.
