I think the barest minimal is
- stock head unit (keep your current head unit)
and buy
- front component speaker 5" with tweeters
- subwoofer 10" with small box
- one 4ch amp
- some sort of crossover
I reckon parts (no name brands included) will set you back almost RM2k
.. stick with 10" coz bigger sub woofer will require more power and that means more expensive amps
.. 5" fronts are recommended coz they' prolly fit in your car more easily and they have good compromise of size and vocals
.. 4ch amp are good bargain coz you can drive your fronts with 2 channels and bridge the remaining 2 for your sub (i've ran this b4)
.. crossover are required (I'm thinking of a particular installer in PJ who makes custom passive x-ver)
Wiring the whole car for the amp will require another few hundred ringgit depending on quality of fuses, cables and fabrication
What you can skimp on initially :-
- amp - I used a Sony 4ch 35W amp I bought for RM260 many years ago from Cosplus!
- crossover - use passive initially - you can upgrade to active later. Active x-over gives you the benefit of having a knob to tweak the volume of the sub
YOu can later buy an active sub to work together with the passive (again, a particular car installer's brand)
- front speakers - use no-name or inhouse brand first
- head unit - keep your existing ...
You'd be able to get the satisfying sub bass this way. Vocals, particularly female vocals will shine. With right tuning - the music will stage nicely from the front.
edit : just saw Saat's post .. I might as well be open and say I was referring to Tehnichi ... but dang.. they are exp$
The above set up should set you back RM2-3k. You will prolly find the following weakness :-
- vocals somewhat lacking strong mellowness (cheap 5" mah)
- mid bass not ummph enough (due to low power 4ch amp)
- no rear speakers (not enough amplifier channels to drive rear)
...until you sit in someone elses car then the infection sets in!
Upgrades / add ons :
- better 5" or even 6" (refabricate door to fit larger speaker) - you can relegate old 5" to the rear
- active x-over - lets you control the sub
- MORE POWERful amp .. stick with your 4ch and buy a new 2ch amp to drive your sub... yeah.. some $ to rehouse existing gear to make way for new amp
Phew! Sounds fun... I feel like starting all over again
