Car Audio: Idiot seeks help

[Seraphim]

Hello,

I've just bought a Kenwood head unit, and I'm thinking of what the next step will be in my quest for a well set-up system. But I don't know much, and have lots of questions floating around my noggin.

1) I'm pretty set on going for quality door + rear speakers combined with a sub and amp tucked away in the boot - can't be bothered with the hassle of parcel shelf 6x9s. But what should I go for first?
2) On the subject of amplifiers, should I amp my front speakers? If so, is it possible/a good idea to get a 4-channel amp and use it for both the sub and front speakers?
3) Speaking of front speakers, I understand component speakers give the best sound quality, but is it worth the effort of installing them in a Rover 214 which has no built-in provision for the tweeters? Are they that much better than decent 2-ways?
4) Does anyone know off-hand the size of speakers for the doors + rears of a Rover 214?
5) Are custom sub enclosures too much work and too hard to get right? Should I stick to a pre-made enclosure?

Thank you all!

Awesome, thanks for the advice so far fellas.

What is your budget in total?
Excluding the HU, I'd say £300-£400 all in (including wiring, sound deadening etc.)
Budget for each area?
£200-£250 on sub + amp, £100-£150 on fronts, whatever's left for misc bits.
Have you made cost allowances for some sound deadening?
Not exactly, but I'm aware there'll be costs extra to the hardware. I'm not planning on deadening the entire boot/doors (unless rattles develop) - maybe a little in vital places, but nothing extreme
Ported or sealed box? what size sub?
Ported. Nothing extreme size-wise, 12" at the absolute maximum.
what kind of music do you like?
In the car it'd be mostly electronic music - I am somewhat in love with basslines, so having good quality and range of bass, not necessarily sheer volume is important to me. Drum and bass sounds like rising and falling sine wave bass could really highlight a bad install, I suppose. But in general it's a little bit of everything.
