hello everyone!

i hope you can help me out.. i don't really know much about car audio. anyway, i was thinking of having a sound system installed:

amplifier/subwoofer/separates/rear coaxials.

i'm currently driving a '97 honda civic.. stock HU and stock speakers.. the only thing i've added so far is a cd changer.

i'm sort of aiming for 60% SQ and 40% SPL, and my budget is approx. P20,000.

could anyone please advise me as to what brands i should get, and where i can get them from? a breakdown of the costs would also be greatly appreciated.

many thanks! 8)
