PJP, I don't think you will be satisfied with a 4" speaker and a subwoofer. You will miss a lot of mid-bass frequencies.

4" is not good enough to deliver an even full range experience above 70hz.

Sir do all head units have the same connectors ? I want to replace my 7yr kenwood 4026g with pioneer 149 usb Hu . As I want to retain my speakers , and I can remove my head unit out of my dash by myself , regulary do so to clean the cd lens as the playr being old now skipping I do not wish to have an installer cut wires in my 04 alto as I had earlier bought the Hu from the dealer and they had installed it for me . So is it simple plug and play ? Hu power supply connector ,speaker wires (L/R) and antenna wire ?

It actually depends on the system. Look out for a system with the same "back" and it should be a plug and play job. The existing wiring can be used. Also, to change speakers if needed, the existing wiring can be used, just replace the speakers at the other end.

Having said the above, it is advicable to change the wiring on your car, since its nearly 7 years old.

New Wiring + new HU + new wiring will definetly increase the sound quality of your music.

Sam, it feels you are correct.
Reminding you of my sorry looking budget of 10,000/-(max).
I'll keep the rear speaker (have only one as one got stolen recently!) and connect it to HU. May be this will give me some mid bass. I'll fix a new pair maybe couple of months later (GTO 949, got a quote of Rs3200/-)

Front: JBL CS4 (got a new quote today Rs900/-)
AMP: JBL GT5 S644 (new quote Rs5400/-)
Sub: not yet finalized, may be a 10" JBL 1100 Watt (Rs2500/-)speaker and an encloser.

As of now this is the plan. Know not at all perfect but...
One doubt, will the above amp which is of 800 W only, be able to power the sub (1100 W) adequately along with the fronts?

Do comment on anything!

No. But often different head units from the same brand have the same type of connectors.

Your 2004 Alto must have already had its wires cut in order to install the head unit.
It won't be plug and play, but yes, in essence all head units have the same colour combination for wires

Below is a typical japanese head unit configuration

Yellow: +12V always on
Red: +12V switchable/ignition
Black: Chassis/Earth/Ground
Blue: Trigger out for amplifier (only to be used with amplifier/optional)
Orange: Illumination (optional)

Purple/Purple black, Green/Green black, White/white black, grey/ grey black - 4 speakers

Antenna is usually a plug-in. Motorola type for most Japanese/Korean head units, FAKRA or Euro for European.

Wow 90K is a good budget, Caska HU is good, but the only problem is finding a connector for the Steering controls. It is not available easily i guess. Try pioneer its good and connectors for steering are comparitively easily sourcable.

JBL / Polk audio speakers are good.

Pioneer AVH-P4390DVD - Fits Innova and Fortuner. - 28,000

Infinity KAPPA65.9CS - Front - 16,000

Infinity REF6530CS - Rear - 9,000

JBL-GTX646 - Amplifier - for 4 speakers - 9,000

JBL GTO 3501 - For Woofer - 15,000

JBL CS1215 T - Woofer - 7,000/-

Wiring - 6,000

Installation (Labor) Free when you spend 1 lac on ICE. you should get a 5-8% discount at the very least if you buy all these products from a sngle shop.

Bought couple of items today:

1) GT5 S 204 (Rs900/-)

2) GT5 S 12 (Rs2000/-)

Replaced the fronts and whoa!
Clarity is distinct. Slightly bright on ears, but CLEAR!
Thanks guys!
Now thinking of buying a pair of infinity over GTO 949.
Amp & installations by this weekend

Pls advice if I should go for a ported or sealed enclosure for the 1200 W sub as the amp is about 800W(JBL GTX 646) only

Which is why I figured if PJP HPFed the 4" at 125Hz and LPFed the Sub at say 100Hz he'd be ok given that his budget did not have room for rear speakers.

I thought the GT5 were replaced bt GT6. Never mind.

Great so you will now have a budget for rear fills as well. I'd consider getting 699 GT6 for the rear to keep the tonal balance the same as the front.

Why not 300 W infinity 6x9 coaxials? Won't they be better? Im getting a quote of 3000/- for those.

Nothing against Infinity (JBL and Infinity are both Harman Intl. brands) just was looking at retaining the tonal balance. At 3K per pair the Infinity is a great buy.

Navin, many many thanks for being so patient to me!
Infinity pair will be inhouse tomorrow, no today (its 1 am now)!
Im going to put them in sealed boxes, no tray!

Pls tell me about my sub-woofer box query above pls!!!
Ported or sealed?

One doubt, will the above amp which is of 800 W only!

The amp you are using will probably deliver about 150W rms 2 channels bridged @ 4 ohms. Sam knows more but it is defintely wont deliver 800W to your sub.

However 150W is adequate for the sub. In a sealed box the volume of the bass will be lower but the bass will be a bit tighter (aka better defined). In a ported box you will get more volume but less definition also IF you are going ported AND if the amp has a subsonic filter (HPF at 25Hz or so) use this filter.

Sam, need your thoughts (on bold & underlined) please.
Sub: GT5 S12
AMP: GTX 646.
Think I should go for sealed box (L40 x D38 x H36 cms) as ported boxes are bigger and I have limited boot space.
