I just finished my sound quality install today so here's my recommendations. I love alpine so keep that in mind.

I'll post pics in a thread soon of the install but here's what I have now:

Alpine INA-W900BT double din head unit (added the kit that allows steering wheel control for volume, etc)
Hertz MLK2 components up front (don't use rear speakers as they're not needed ever in my opinion)
1 JL 300/2 to right side, 1 JL 300/2 to left side, 1 JL 250/1 to the sub
Dayton Reference HO 10" sub (awesome sound quality sub for only around $140.00 at parts express).

Speaker cable used: KnuConceptz 12 gauge oxygen free wire
KnuConceptz RCA Cables (very good and cheap too)
Custom ported 10" sub box. Or if you want a prefab box Zenclosures sells them on ebay.
Doors tripled layered sound deadened with Stinger Road Kill Extreme.
Tweets custom mounted in the A-Pillars (best tweeter sound I've ever heard from this position)

This is my current setup and the best sounds system I've had after being in car audio for 25 years. Good luck!

p.s. just now saw you already had some equipment. Anyway, definitely get the sound deadening in the doors and the KnuConceptz wires are good for cheap prices. I'm also getting the Bit1 processer soon for sound tuning which makes a considerable difference in sound.
