Guys,
After surfing around a lot (internet, shops & gurus) for an ICE upgrade for my humble ALTO, I finally did it last week. Here's the final config:
OWNED EARLIER
PIONEER 7750 HEAD UNIT
ALPINE SPA170 6" CO-AXIAL SPEAKERS (REAR)
ALPINE 4" CO-AXIAL SPEAKERS (FRONT)
BLAUPUNKT VELOCITY VXB12 REFERENCE SUBWOOFER
BLAUPUNKT MPA4 4CHANNEL AMPLIFIER
http://www.blaupunkt.com.sg/download/en-GB_MPA4oi.pdf
NEWLY PURCHASED
ALPINE V12DIGITAL M605 CLASS D MONOBLOCK AMPILFIER
BLAUPUNKT VELOCITY 5.25" COMPONENT SPEAKERS (FRONT)
BLAUPUNKT VELOCITY 6"X9" CO-AXIAL SPEAKERS WITH CROSSOVERS (NOT INSTALLED)
MONSTER CABLE WIRING AND CONNECTORS
MONSTER CABLE DUAL FUSES WITH CIRCUIT BREAKERS FOR POWER SUPPLY
I was very much disappointed with my earlier setup. I used my blau amp earlier to power my sub bridging all the channels, My rear speakers (SPA170s) were bolted onto the boot door and front speakers were kept in dash wells near the windscreen and these all were powered from the Head unit. And the bass it produced was dreadful as it just never gave enough punch and sounded lifeless. Only the highs sounded good. Vibrations produced were too much as the rear speakers were in the boot door.
I did a lot of querying in various forums, many shops, lot of audio experts etc.. And thanks to them all (especially gunbir etc..) I came upto a conclusion to change my AMP and SUB. I sold my BLAU amp and my VXB12 Sub to a nearby friend. He was very much tight in his pocket and after waiting for a month for the payment, I decided to take my stuff back and I did so (Now I am glad I did'nt sell those).
I went to and audio expert here in my town and presented him my scenario again. I had done this plenty of times earlier too but he was quite hesistant to work on my ALTO, and used to recommend me to buy a big car to suit my demands. I spoke to him again and offered him to take this as a challenge and he accepeted.
Speaker installation
He made a nice padding for my front doors using MDF, installed the velocity woofers into it.

And the tweeters were installed in the A pillar.
For the rear, I wanted to install Blau 6X9s. But could'nt find a suitable place for doing it and I did'nt want the soundstage to be shifted behind also. So, we decided to stick with the alpine co-axials. Those were placed in the rear doors.
The Alpine SP 1003 4" co-axials are there in the dash wells but I disconnected it after experimenting with the sound. It sounds very high pitched with those connected.
SubWoofer installation
Subwoofer was kept in the boot as before and the connecting cables were changed to monster cable.
From inside the car:
Boot open:
He also put a blue neon light wire inside the glass enclosure surrounding the SUB. It pulses according to sound. Looks really cool ! !
Amplifier installation
The Alpine 605 monoblock amp was fitted beneath the driver seat and carpets were arranged to make airflow to the fans. The Amp has a hood which itself is a protective cover from dust and other nuisances. The controls are fully digital and no fooling up with the settings here. It also has a blue backlit digital display which looks really cool.
The Blaupunkt MPA4 was placed under the passenger seat and again the carpets were arranged to let air flow outside. The Blaupunkt logo lights up when the amp is switched on.
Sound proofing and dampening
Now, here comes the most interesting and difficult part of the install. If any of you have tried pushing the volume in a normal ALTO, you'll understand what I mean. The car is very feeble in many parts and those areas will vibrate horribly with subwoofer bass. Even the doors and doorpads vibrate too. I wanted this to stop and did a lot of homework to find a good solution. I thought of fibre, dampening sprays and Dynamat. Finally as I could'nt get Dynamat Extreme locally, I went for WURTH. My audio man installed it in every door, C pillars, roof and some parts of the floor too. It took us a lot of effort doing so. especially the C pillar vibrations were very difficult to put off. Once it was done and my system was powered on, I knew it was completely transformed to a different animal. It was sweet sound coming all around. it felt as if the sound was coming from a live band. Each instrument was to be heard!
I could'nt get any pictures of the sound dampening as I completely forgot about it before finishing the install. (Talk about getting involved in the work).
Guys from Ernakulam and around are welcome to pour in and have a look.
Special thanks to GUNBIR. His INNOVA install pics helped me a lot.
Bye for now,
