Crutchfield car audio set up?

I'm getting my license soon and i'm looking forward to replacing the current sound system in the car i'm getting. The car I'm getting is the 2001 lincoln ls without the alpine audio system. One of the weird things about it is that there's a cd changer, but it's in the glove compartment. How will this be affected with an aftermarket head unit.

These are the parts i'm looking at currently (I have a decently low budget and i'm looking to get a subwoofer, component speakers, a new head unit that has usb and bluetooth, and a pretty low power amp. I'm not looking for top of line parts that go above and beyond, but i don't want something that will break instantly.)

I'm pretty sure i was looking at an older version of this and this was released not too long ago, (btw i have an iphone 5 and this head unit has some new siri features i guess so it works out). Also, before i knew i was getting this car i was limited to a single din receiver, but now i don't have that restriction. If i were to get a double din it would be this one which is pretty much the double din equivalent of the older model i was looking at

i do seem to like the appeal pioneer has so i'm looking at those currently but if there's something better for the price or anything i don't have a problem changing that. ( someone had told me though that because pioneers have a 5 band equalizer it can make it sound bad, opposed to a 3 band, but i'm not too sure about this)

component speakers:

i don't know all that much about the component speaker selection so i just chose a fairly cheap pioneer set with a good rating, does anybody know if these are good?

subwoofer:

so far i'm liking the look of this sub its cheap, fairly powerful ( for my car i probably don't even need this much)

amplifier:
i'm not sure which one is best to get for this subwoofer

i will probably get shunned for choosing such low price amps but this is what i'm looking at and i would like to know which one is best for me.

are these parts good? What would you guys recommend? I'm open to suggestions.

also my last question is, who should i have install it? Should i figure it out myself ( i have never done this but my father is somewhat familiar with what to do and he will help me if i choose to do it). Or should i pay a company to install everything? I guess my last option would be to pay a friend who has had plenty of experience with car audio, one problem with that is if something goes wrong with the installation.

You will also need the wiring harness also n i would have it installed by a pro cause wiring up a amp is not that easy n if you have installed by a pro everything will be blanced
