You could also use Kappa in .8 cu.ft enclosure with added 300-350 grams of polyfill. kappa will be 3db louder than the ID at 2ohms. That's like have two ID subs.
I guess you gonna power with the DLS RA10 ?

Here's what the Infinity Kappa sub manual has to say,"The SSI 2-ohm setting increases the subwoofer's output over the 4-ohm setting by up to 3dB, depending on the amplifier, Performance is identical in all other respects, If the connected amplifier is rated for 2-ohm operation and its 2-ohm power ratings are within the subwoofer's power-handling specifications, setting the
SSI switch in the 2-ohm position will achieve maximum output."


Looking at the sensitivity Kappa is rated at 91db at 2.83V which means it would do around 88-89 at 1 volt. IDQv312 has a sensitivity rating at 87db but it's no where mentioned that it's at 2.83V or 1V. Even if we consider it to be at 1volt, kappa still has an edge with slightly higher sensitivity compared to ID. Kappa also has a Lower Le and Bl where as in ID's case these numbers are not mentioned in the spec sheet.
Now with the given power of 500RMS in 1 cu.ft. with the sub being placed at 5.5feet away in car (an avg) the IDQ will put out around 109.5db SPL compared to kappa which will put out 111db SPL. This is without adding any sought of cabin gain. Kappa has triple voice coil design against the standard dual voice coil used in other subs. Now if we go by what the manual says running the sub at 2ohm will add 3db more output. Which means kappa would result in putting out 114db.SPL against that of the ID.

Using .8 cu.ft enclosure is good enough with 300-350 grams of polyfill as it will add volume by 20% bringing it to .96cu.ft. There wouldn't be much noticeable difference between .96 and 1cu.ft when it's a sealed enclosure.
Hope that helps!

Using .8 cu.ft enclosure
We cant compare the Le, BL and Mms of the 2 subs are these specs for the ID sub are not given, that said the Kappa does look better suited for a small sealed box (small Vas, slightly higher Qts, etc..) than the ID.

Navin I just thought of mentioning it about the Le, BL. ID manual doesn't state anywhere about these.. I wonder Why?

By Le & BL, do you mean the Thiele and Small parameters ?

here's an attachement of the IDQ spec for your reference.

They are part of the Thiele-small parameters. Le stands for VOICE COIL INDUCTANCE without going into details generally it's considered that lower the value the cleaner the sub would sound. BL stands for Motor Force Factor.

I am looking for 4awg wiring kit/kits to power up the 2 amplifiers (1 2ch & 1 Mono blk).

1. There is a dual amplifier kit from kicker which cost $115
Kicker 09PKD4 - 4 Gauge Amp Kits - Sonic Electronix
What I understand from the specs of it is that the second amp would be connected using the 8awg cables instead of 4awg. Is my understanding correct ?

2. Alternatively can I go in for 2 separate 4awg kits which works out to $120. The kits I have in mind are (in my order of preference) ...
a) streetwires kit
StreetWires PSK04B - 4 Gauge Amp Kits - Sonic Electronix
b) Kicker kit
Kicker 09DPK4 - 4 Gauge Amp Kits - Sonic Electronix
c) Stinger kit
Stinger SHK241 - 4 Gauge Amp Kits - Sonic Electronix

Gurus, please suggest which of the above would be a better option.

Also how are kicker RCA's ? Is (refer to link below) it worth going for ?
Kicker 09ZI25 - 13-18 Ft. (4-5 Meters) - Sonic Electronix

Quick responses would be much appreciated.

Thanks.

Congratulations, Arun.
One headsup about the HU, it's gonna make the equipment sound bright.
So, run the full range crossovers at the most attenuated setting and decide if you'll have to use the EQ as well.

Wow, that's an incredible collection of components! I guess over a year's research went into the selection.

The only component I am slightly familiar with is the HU. I have heard it in a couple of setups including Sathee46's and the SQ is superb.

Good luck on buying a car that can house the ICE. I bet you are tempted to install them in the Santro itself.
