Thank you, zucchero and JK! :-)
JK, I'll meet up tomorrow. Are you going back to Bangy by bus in the evening?
I got back from my test-drive by 9.00PM. Drove a whole lot. Listened to a whole lot. It is
all good. I'm satisfied and happy. No problems with the equipment in extended non-stop listening sessions. Nearly all types of music that I wanted to check out I have now checked out. The CD Changer doesn't skip even in the roughest patches. Now the A/c cools the amps also (no parcel tray, boot open to cabin) which is a good thing.
I can sleep in peace and with contentment today.
But uhhh... one small worry is about how I'm going to protect the front speakers (in the door panels) from overzealous service mechanics and water-hose/compressed air blower accidents. I'll be getting rexine covers made for the 3-ways so I can velcro them on before I give the car for any kind of service/wash. That should fix this problem.
Another concern is careless passengers who may kick the midbass drivers/grilles or the XO while getting in or out of the car. Maybe I'll get a long, thin, strong double bars (separated by about 2 inches and finished in stainless steel/electroplated maybe) and fix the bar so it goes over the XO and the midbass, covering the length between the XO & midbass driver. People kicking the bar will be ok.
I'm anyway getting three-bar like things made, to act as a grille/protection for the sub's cone. Since there is no parcel tray, rear-seat passengers (though they are rare, sometimes I do need to haul some people) may be tempted to unload their stuff by tossing things directly into the boot, and then these things may land on the sub's cone -- right now the cone is naked and open to the elements.
The third concern is security. Now every tom, dick & harry can see the equipment in the boot (no parcel tray) and scope it out. I hate tempting potential thieves going about their business elsewhere. I already got a lot of oglers today at the traffic signals and at the place where I'd parked the car for lunch looking into the boot and lusting after my stuff. I do have a Nippon security system in the car, and my home parking is totally safe. I'll work something else out. I kinda like the sound with the boot open to the cabin, and the fact that the AC cools the amps well. So I dont' want to get a parcel tray done. I hate getting dark tints done (ruins my night-rear-vision) but maybe I'll need to compromise here at least for the rear window.
Now for the other additional details I'd mentioned yesterday: A few BHPians had wanted to know how the doors look when they are closed, how the sub was set-up to be "removable", and how the LED bars were setup, and where the switch for switching the LEDs on and off was fixed. I'll post the details and pics here so everyone can benefit.
1)
How the doors look from inside when closed:

2)
Sub connection: As an additional safety feature, the sub's wire is connected to a socket wired to the amp's output, and not vice-versa (wire from amp connected to a socket in the sub). This was done so there is no problem of the wire from the amp getting crossed (when the sub is removed) and potentially blowing the amp. The output from the sub amp terminates at a push-to-remove type socket situated right below the amp on the RHS panel in the boot.
An additional advantage is that if the socket was on the sub-box, sealing it for leaks would have been a bigger problem, than just have a very small outlet on the sub-box so that the wire trails out of the sub.

3)
LED Tubes: I had two 1 ft LED tubes installed under the dash, lighting-up each footwell, and a 2 ft LED tube installed on the rear-most part of the roof (just before the hatch-lid, and just above the part where the boot begins. The tubes are wired to the door sensors, so that they turn on when the doors are opened, a-la the courtesy light. A switch was installed just on behind the gear-lever console so that I could turn off the feature, i.e. if off, the LED tubes wouldn't light-up when the doors are opened. In addition, when the switch is on, it works with the courtesy light, so that when I switch the roof light on, the LEDs also turn on.

So this is about it for the install report. No more pics to post :-) I've updated the info and ICE pics in my TBHP garage.
I'll post pics of the rexine protective covers and the protective grill/bars when I get them done. I'll need to do some work at office this week (last week was wringing-my-hands-waiting-for-the-install-to-be-completed week -- not much work got done) so I may take some time getting these done.
My wishes for a very happy new year to everyone!
