this is exactly what one should do. Actually you could also run 2 way for the front using the passive midrange - tweeter crossover.

I am sure gunbir/JB can cover this in detail. the reason i say this is that the tweeter and midrange really do not need a lot of power. 5-10W for the tweeter and 20-30W for the midrange is more than adequate.

135 Watts (SRx 2S) to the front stage and 170 watts (SRx 4 bridged on two channles) to the sub-section in that case.

I would any day prefer bridging the SRx 4 (170 Watts X 2) on the front stage and SRx 2S bridged (600Watts) on the sub secion and run the rear fills off the headunit.

Hmmm... Now let's not get me started with ideas :-) The more I discuss the more trouble I will be in.

I actually don't want to run the rears off the HU (want to keep the HU's internal amp off, and I do like a teensy-weensy bit of rear fill), and that's why I prefer the rear speakers to be amped. But I will need expert advise when I do plan the upgrade (8-10 months later).

JB, won't bridging the SRx 4 leave it in a normal '2-ch amp without crossovers' mode? The Butterworths are on only on 4-ch mode?

I do have a 4-ch amp lying with me (Blau GTA450) that can be used to run the rears & the sub in 3-ch mode. And I can use the SRx 4 to power the 3-ways in front (with 170w RMS x 2)?

I didn't do this at first, because I wanted fronts and rears to get the same quality signal. Maybe this was wrong?

I have used a GTA450 (to power subs and rear)in my wife's car and I found it a bit harsh. I have not heard the Srx4 (in fact I have not heard any Audison product - Gunbir and JB seem set on only allowing Delhiites to listen to stuff like Mille and Audison etc... - maybe we Mumbai Munchkins are not sophisticated enough - LOL - just kidding) but I assume the Srx4 will be a lot sweeter and smoother.

What you really need is 7 channels of power. Very approximately 1 x 250W for the sub, 2 x 30-50W for the rear, 2 x 70-100W for the midbass and 2 x 30-50W for the tweeters. 2 4ch amps can do this. 1 4ch (70-100W per channel) amp cna power the midbasses and sub (2 ch. bridged) and 1 4 ch (30-50W per channel) can power the tweeters and rears. Just make sure the 2 amps have very similar tone. However if one wanted to use dedicated amps one could make do with different ratings for exmaple the tweeters really dont need more than 10W or so but finding a good sounding 10W amp is not easy unless you go DIY or very high end.

Navin, I have 3-ways in front. I'll need 2 more channels for the midranges. :-) That would be 9 channels. I would love to go active like you've suggested with my next upgrade, but then I'll need a better HU that lets me go active, or a separate active XO unit. And a 6 ch Amp. I don't think I can go that far :-(

Ya, the GTA450 is a bit harsh. That's another reason I didn't want it to power any speakers. Powering a sub with it is ok, as the difference is not that much when you're looking at low freq alone.

Audison amps do sound really smooth and sweet. In fact, if they were driving the same speakers as before I'm sure the difference (between the GTA450 & the SRx4) could have been noticed just like that, even by somebody who is not that much into audio.

Like me? Right? :-) LOL Just Kidding. BTW I dont do much audio work now. My family and work are about all I can handle.

You can go active passive as well. leaving your midrange and tweeter using a passive crossover. You alreday have a good 60W x 4 ch. amp (SRx4).

I would get the SRx3 amd use that for the midbass and the sub leaving the SRx4 for the tweeters and rears. If however you want to triamp get the SRx5. Use the Srx 5 for the sub, rear and tweeters and the Srx4 for the woofers and midrange.

Default V2 Turbo - ICE'd

Hi Guys,


Got my system installed this Saturday. Had got this Radiowarehouse place on Wajah Road, Chennai recommended from quite some people so went straight there. Was short on time so had taken out 3-4 hours to do this.

My budget was very tight of around 12-14k. I wanted an HU which had a USB interface and MP3 playback. The decision on speakers was more or less very dependent on how much would go in for the HU. I wasn't going in for a Sub and AMP (maybe would go in later as upgrade ).

So it was two front speakers in the Dash and Two Ovals at the rear with a wooden tray in my Indica, pretty much a very basic install.

After lot of looking at the tonnes of HU's available and doing a lot of bargaining i finally decided and approved of the following configuration. Everything is with B&W.

Setup:

HU-
Sony Xplod GT460US - Rs 8990/-
USB and CD playback
(http://www.sony.co.in/productdetails.do?prod_id=964)

Rear Ovals-
Blaupunkt GTx 693 - Rs 3200/-
(http://www.blaupunkt.com/in/7606427001_main.asp)

Front Speakers-
Blaupunkt BGx 402 - Rs 1500/-
(http://www.blaupunkt.com/in/7606440000_main.asp)

Wooden Tray-
Rs 700/-

Install-
Rs 450/-

Total Rounded off to Rs 14,000/-
----

Warranty on HU is 2 years and on the speakers is 1 year.

Its such a basic setup that I didn't expect too much out of it. But the system suffices my need and the front USB slot is a delight where I just plugin my flash drive and I'm good to go.

I've started saving up on my next upgrade of front components, an AMP and a SUB.

Thanks
Saurabh

Yep!

ICE was very necessary for a 10+ hour drive. Without it is like playing a video game without any sound

@E_L: So whats your status on the long drive?

An Accent CRDI got iced.

HU: Pioneer 7750 (old one removed from my Alto). Price: 0
Front Speakers: Hertz DSK130 5.25" components. Price: 5.8k
Rear Speakers: Hertz ECX165 6.5" co-axials. Price: 5.9k
Sub: Kenwood (Got it from a very enthusiast Team-BHPian). Ported box firing upwards in the boot.
Amp: Blaupunkt GTA250 2 channel amp ( " ). Price: +/-6k for Amp, sub & ported box.
Wiring: RCA from Audison, Twister used for rest. Price: 2k

Install: Done at Emperor, Cochin. By Zuhemi. Price: Free (Equipment bought from the shop sufficed as the cost of install).

It sounds amazing! For the money spent, I think it makes a great setup. Would be gathering some moolah soon and change the HU to an Alpine.

Speedzak, good install. How does the GTA 250 sound? Will GTA 280 be better than this model? And, how much you got the 250 for?
