For tweeter you need:
1. Flathead screw driver (supplied: in your boot)
2. 8mm hex socket and suitable wrench
3. Small spectacle flathead screwdriver (0.5-1mm)
4. Wire tape
5. A pair of tweeter (usually comes with all the wiring)
6. Doubletape or superglue (to stick the tweeter onto the panel)
7. Clean cloth to cover dash surface during installation
First, to dimantle the HU, pikkashoe have shared the step by step instruction (thanks pikkashoe)
http://www.insightcentral.net/forums/modif...tock-radio.htmlTo dismantle the tweeter panel:
Using the flathead screwdriver, slot in the tip into the opening and pry open gently. You may need to twist the screwdriver all the way until the clip of the panel release.

Gently pull out the tweeter panel towards u. Attached here is my panel with the tweeter already in place.

Depending on the type and size of tweeter use, u can either attach them onto the panel using doubletape or few drops of super glue.
Insert the wiring from the panel hole towards the bottom of dash. Re-route the wire properly behind glovebox toward the HU slot.
Tap the audio signal based on this diagram:

For the left tweeter, tap the audio signal from Light blue (+) and Gray (-) from the original harness.
Repeat the same procedures for the right tweeter. All the panel below steering column are removable and only attached by tabs and 1 screw tab if im not mistaken. Its important to properly route the tweeter wiring for the right tweeter to prevent it from dangling the steering shaft.
Right tweeter will tap audio from Blue (+) and Red (-) from the original harness.
To tap the audio signal, depending on your skill, u can split the wire (not recommended) or undo the pin from the connector (harder but neat). Tape the wires properly. Make sure no loose contact or worst, short circuit.
Put everything back in place and u are now can hear shattered glass sound better than before.
For improve bass effect, u can use something like this:
[attachmentid=2205042]
This type of active sub equipped with built in amp with gain, phase and frequency setting. Most of them now have wired remote bass control so u can increase or decrease bass level without the need to set your gain, again and again (coz different media source usually have different bass level).
U have to undo the font driver seat, get the harness all sorted out through the gear console panel (side) and tap the audio signal accordingly as the color code above using sub speaker/ high level input, from rear left and right (4 wires) behind the HU (same step as the tweeter above). Power for the active sub can be tapped either direct from battery or like me, easily tap from interior power socket. 120W limit for power socket should be enough to cover the sub consumption. Tune your gain, phase and frequency right.
All done. Get the HU back in place, reset everything. The difference in sound quality is night and day.
Will try your instructions and get it done when I have the courage to do so haha... (pretty noob in handling these stuff). Thanks again bro~ for the share, Really a big help!
