Get an Alpine CDA 105 with Alpine SPR17S and rear fill SPS69C2 with a 12" ALpine Type E in a sealed enclosure, a good JBL Multichannel AMP and a Kenwood M series or Sony GTX low power Mono AMP.
YOu can slowly play with filters, EQ and installations and then upgrade to anything you wish.
Maybe it sounds funny to you but eventually I can make it sound better then your Focals and Pioneer combined worth much more.
These Focals are installed in BMW 5 series and Meredes E class and they are no good in local Corolla or CIVIc even if you wrap the whole car 3 times with Dynamat.
There are no shortcuts to success, you cant just throw your hard earned money on expensive components and hope to get the best sound out of box.
The best car acoustics and gain in local cars is of Mitsubishi Lancer, Accord and City (old one).
As Mr Lafafa said, you have to drop the Pioneer A/V player for serious SQ.
Do not go on online reviews, their music preferences are different, their stuff is different and their installations are also difference.
I have yet to find good quality 5/8 MDF, JL color coding wires or even the spacers here which are easily available at any audio shop in Canada.
I have listened to the JL ZR components and their tweeters are the best available this side of Polk SR or Hertz HSK and mid bass is also as good as any Focal KR or Pioneer reference series, I do not know why you are going for anything bright, Focals are surely bright out of box but once you are get used to it you will start liking them.
Trust me, an Alpine Type S Component sounds no where in my 05 EXI PROSMATEC which it used to sound in Canadian LX Civic and neither you should expect that Focals worth 37K Rs will be the same as available on CircuitCity for 1,000$.
