I don't know anything about SQ and SPL. Should I go for SPL?

It's ok if the setup isn't that good, as long front & rear speakers added + hard bass boom boom boom can already. I don't want to spend so much on car, because there is risk having to park the car outside. 

Yea, I plan to get the Pioneer HU, so left about RM1.3K.

And err...

- Do I need to use a better battery?
- Do I need to do grounding, optional?

Omigosh, didn't know that we need to pay for the wiring...   

Wanna ask, the 1 normal component set, that includes 1 pair of speakers, with tweeters and...? Is it a 2 way speakers? If I want to fix front and rear, that means I need 2 x component set? 

zeist, please remember this. this is solely my own opinion only, and is base on my fren's car's experience. please avoid 2 set of comp, please.

do not install 2 sets of component speakers for front and end. wad i really recommend is a set of component speakers and a set of coaxial or even 6x9 speakers for the rear. the rear of a car should always only hav midbass and vocal. no high notch. installing of 2 set of components in a car will conflict the sounds produce by the components.

you CAN install 2 set of components, but it is advisable not to. the quality of the sound will drop. somehow, if you listen to the car setup for long, you'l get the feeling tat you're not satisfied with it, and feel there's sth wrong with the sound, somewhere.

usually, it'l be:
-hu (*norm also can, stock also can to save cost)
-component set (*+ electronic x.over if possible, to improve sound adjusting)
-amp, preferably 2 or even 3. but 2 would be sufficient. china brand also can. monoblock to power sub, and 4-channel to power comp and coaxial)
-sub

lately, soundstream has let me down abit. dunno why. instead i got attracted by Eclipse. but tat's just my opinion lar. XD

Dudes, I'm in dilemma now, since I have no knowledge about ICE, I'm having trouble choosing the right setup.

Thanks for all the helpful inputs.

In regards to barry's post... 

1 normal HU-rm200-rm300
1 normal amp-rm300-rm400
1 normal component set-rm200-rm300
1 normal sub-rm300-rm400
1 normal sub box-rm50-rm100
I'm planning to get...

1 x Pioneer HU
1 x Component set
1 x 2 channel amp
1 x Sub

The sub box is it necessary er? I plan to get a good HU and Component set (can recommend me a good component set?), the amp and sub can use some 'not famous but can blast loud brand', but not so ciplak ler. 

With these setup, can blast already?

Btw, are you guys from IASCA? 

If follow the barry budget, hard to get a good system; I can say only decent system.
Plan your budget if posible go for 1 by 1 upgrade.
Too rush may regret.
