lets say:

RM1000 for HU
RM1000 for Amp
RM1000 for Alll Component
RM500 for cable and installation

any suggestion of brand and shop for my upgrade?

more on R&B and pop

i need suggestion, since i'm not a bass head, was thinking maybe 2x 3 way speakers for rear, 2x 6.5 for mid and 2x tweeter.

do they make my setup wierd?

screw the 3 ways....get sub better. and ur budget is actually alright.

my suggestion (not listing brands) get these parts

HU

2x 2channel amps
-1 for front components
-1 more bridged for sub
*try avoid getting 4 channel to power sub and comps... might have issued with amp cutting off due to not enough power or overheating.
* can try getting the brand prokick or agako for amps...good and cheap

6.5" 2-way component speakers for front

10 or 12" sub with enclosure.

this would give u a nice setup with good soundstaging.

the rear speakers if u have money to spare then get components or coaxial and run directly from HU. get 2-way oso... if no money then stick with stock speakers should be ok.

electronic crossover should get if ur HU has only 1 pair preout. but if got more than 1 pair then can forget about the e-cross...

as for shop....dunno ur location how to tell u which shop?

i was told that kklau is on a higher price tag, but satisfaction guaranteed la
