Thanx for the input =)

The price doesn't match with the links I put because they are just tehre for technical reference.

That head unit for example. I found it going for $300 in most local retail outlets here, around 240 on many online store and for 168 at www.ikesound.com !! It goes the same for every other component I picked up. Saving over 50% on the retail price

Regarding the bass, I didn't want any bass box originally. Don't really have the time or ressource to work on it, and I figured out that I'll need a mono amp along with the subwoofer and the box, which will bring the price in the 200 range with some homework to do and fat box in my trunk .
The basslink is rather small... all in one solution without headache, and i was thinking about removing my spare tire and make it fit down there. You think it's gonna work? :/

Also... you mentioned dynamat... is it some extra I have to get and dump almost everywhere in the car?

I am also kinda concerned about power supply... Do I need any kind of extra electrical equipment? I don't want the amps to suck down all the juice from the battery and alternator
