hi guys,
need your help.
i just got a new cd player installed in my waja.
the problem is i think the guy did a bad job, the bass is simply non-
existent.
a fren mentioned that he faced a similar problem in his old car, and it
was caused by mis-wiring (+ and - wiring mixed up)
so im thinking of checking the wiring myself.
can you guys help provide what each colour of the wire in the car
represents?
cant find it in the manual.
cant find it anywhere in this forum too...

thanks

If u just installed, go back to the shop that u fix it and show the
problem u are facing and ask them to check the wiring. I think should be
FOC instead that DIY it will take risk.

i know i can do that. the thing is i feel "pain" when i see the way they
dismantle the front to fix the cd-player. would prefer to do it myself :)
the other thing is im now in my hometown for CNY, and will only be going
back after CNY. would like to get this fix so that i will have a more
enjoyable ride back :).
most if not all the shops here are closed. you know lar.... tangan gatal
wanna try it myself. :)

thanks

from the original wiring.

fcbgaX,
my Sony Rear Component speaker is round wan and the size is the same size
as the Original Speaker ,..as i dont see the installer potong any part of
the metal bracket lor..

is original speaker 6 or 6.5 inch?...this wan im not sure lor..he just
slot it in,..screw it on,,.KAU TIM liao,..and do the wiring of course!...

by the way, i missed the part where he remove the rear seat 2 side
cushion lor,..if not remove, the speaker board cannot be slide out
ma...so,just wanna ask u know how to remove the rear 2 side(left and
right) cushion?..can give some tips on how to remove them arr?..

i think any speaker size bigger than the original speaker,,the existing
speaker metal bracket has to be potong /modified in order to install for
example a 6 by 9 or 7 inch speaker lor..

Kee Leong,
errr,..i just changed to Component speaker only lar,..no amplifier or
subwoofer installed also,,

and the most about the speaker wiring is,..if not install properly, no
sound come out only lar,..
wont short circuit wan,..its just like your those HiFi Set at home ma,,if
not wired properly, no sound come out only lor...

furthermore, im using all the original wiring, never modified those
wiring into good wan..

set koyak ma..hehehe!

anyway, i change terminal changes liao,,and everything back to normal
liao!..cool!..

My wireman told me that if the +/- sign were mis-connected, you will loss
the BASS. Just swap back and it should be fine.

Waja Rear Speaker - 6.5"
Waja Door Speaker - 6"
