ICE journey with Tata indica Stage I
Dear BHPians!,
I am from Chennai.
This is a build log for my Tata Indica from a simple Sony/JBL setup to a complete DIY 4-way setup with Morel drivers and multiple amps.
The journey started somewhere in May 2013 when I was looking to change my Maruti 800 which had done exceptional duty for close to 12 years. After more than 100000 kms and with added bulk around my waist over the years, I wanted a car that gave a little more space.
I just had a Blaupunkt HU in the Maruti 800 with some 3-inch pioneer coaxials in the front in the stock location under the dashboard. I did not bother much about music in the car and used it only occasionally during long drives.
I was only eyeing at used cars and it so happened that my cousin was upgrading to Chevrolet Sail UVA. His 12-year-old Tata Indica (petrol) was in pristine running condition except for some dents here and there on the body. It had done only 50000 kms and I took it. Being old school Indica it was a sturdy beast.
I just moved the audio setup from Maruti 800 to Tata Indica before giving it away. So this was the first ICE (if you call it so) in the Indica.
A few days later I visited my car service guy for a small issue in the Indica and happened to listen to an ICE setup there. It was a Maruti Swift and sounded pretty good.
I had no idea what it was running except that the HU was a Pioneer and it had a 4-channel amplifier.
I guess the experience got on to me and the ICE addiction started.
I am not a complete noob, have some experience of audio as I had built my home theater setup a decade ago, but kinda lost touch with the technicalities.
I started with a blunder of randomly picking up a used Sony 4-channel amp and a 12 inch pioneer subwoofer and a set of new JBL 5.25 inch components and got them installed at a local shop.
It sounded out and out horrible, the tweeters were shrill, the midbass sounded hollow and the sub was overpowering. No amount of tone adjustment could set it right. I immediately realized that my choice of equipment was the culprit.
So I decided to go the scientific way by reading and understanding the technicalities of car audio setup. I went through a number of ICE forums, read user reviews of products and also a number of technical materials.
I learnt the nuances of staging, imaging, active/passive crossovers, 2-way/3-way/4-way setups, cabling, wiring, source quality and most importantly installation issues.
After deciding on the budget the first thing I looked out for was the HU because that’s were the SQ starts and of course the speakers. The choice of HU was easy.
I was not looking at video capability so the best 1-din around at that time (and even today) was the Pioneer DEH-80PRS CD receiver. It is 3-way active capable, has built-in TA, 16 band EQ, Burr Brown DAC on all its sources at a VFM price.
After lots of deliberations, reviews and budget, I picked the Focal 165V30 components directly from Focal India distributor Prithvi Trading Corporation (Mumbai).
I also purchased a 2nd hand PHD 4-channel amplifier.
I decided to retain the Pioneer subwoofer due to money constrain and decided to spend on a professional install.
After visiting half a dozen installers, I selected Speedfreaks (Anna Nagar). The owner Karthick Raj was a knowledgeable guy and we discussed the installation at length.
Since I did not want to add another amplifier at that point in time, it was decided to go passive with the 2-way Focal as the front stage powered by 2-channel of the PHD amplifier and Pioneer subwoofer bridged on the channels 3 and 4.
Since the Indica front doors do not provide space for stock fitment of the Focal 6.5 inch midbass it was decided to do a fiberglass enclosure in the doors.
I had in the meantime purchased felt sheets and aluminum foil and had done a DIY to paste the foil on the sheets.
By the time the FB enclosure was getting ready, the felt sheet was used to damp the car floor and the boot. Traditional self-adhesive bitumen sheets were used for damping the front doors.
The Head Unit and amplifier were installed and the wiring was completed.
The FB enclosure came out well and the midbass sounded quite good.
We sat in the car to finalize the location of the tweeters. A location roughly 4 inches up on the A-Panel firing at the opposite passengers headrest produced a good staging and was least bright and most detailed. With break-in, the speakers, especially the tweeters were expected to mellow down further.
The location was marked and A-Panels were removed for building the fiberglass pods for the tweeters.
The tweeter pods came out well and an RTA was done followed by fine tuning.
After about 70 odd hours, the setup started to really shine. The staging was quite good and wide and not fatiguing as many think is the signature of Focal tweeters.
It is an inverted metal dome tweeter and needs proper positioning and EQ to make it to shine.
The midbass was the real winner and was playing from 80hz to 3 khz from where the tweeters took over. However the Pioneer subwoofer was a real let down and just did not blend with the front stage.
So the first upgrade due was the subwoofer.
Stage II to follow.
