Hello Gurus,

I am very unhappy with the OEM music system sound in my SX4. Bass is totally non existent and high volume sound is very unclear.

I want a basic setup>> a pair of speakers in front and a pair in back, with an amplifier.I intend to retain the original panel(dont want to waste the steering mounted controls).

I am totally unaware of the technicalities and good brands in ICE (I only know pioneer). Please guide me.

Hi!

Car: Safari
HU: Kenwood 7046BT
Amp: Infinity 475a 4 channel amp.
Speakers are JBL GTO 603 components in the front. GT5 coaxials in the rear.
Sub: JBL 1213 CS. 12".

The amp drives the front components and the subwoofer.
The rear coaxials are driven off the HU.

Problem: The rear coaxials sound very feeble compared to the front components, to the extent of not being heard. If I switch the HU to 2Zone, or switch the sub off, then the rear components are heard.

Anyone familiar with the 7046BT, can you please guide me on what setting can be done to bring the sound from the co-axials up ?

Is adding a monoblock to drive the sub and fire front & rear speakers thru the infinity the only solution ?

for a pure sound quality effect, from the sub, does a ported enclosure sound better or a fully sealed enclosure ?

What is the ideal crossover for the subwoofer ? I'm running at 80Hz but sometimes feel more 'boom' than desired.

thanks for your help.

I have a query quite similar to smrini.

My current setup has 4 channel Amp powering front comps and a sub but since now the car would be chauffeur driven I need some more juice from the rear Coax as well.

Should I put a Mono amp & power sub with it and use the 4 channel amp to power front comps & rear coax?How much would a descent mono cost?

Thanks

Use the 4 ch amp to power the speakers and a mono amp for the sub. The rear ones which are powered by the HU will never match the output and clarity of the front speakers which you are powering via the amp.

are focal access comps better than infinity comps?

[DerAlte]

Are oranges better than apples? Inappropriate comparison.

There is no right or wrong answers to such a comparison. It is a matter of individual liking. Some like the more neutral sound signature of Infinity, some like the slightly brighter Focal. Audition both before you buy - a good dealer will give you audition in a car.

This is interesting.

Do you or any one else know of a dealer like this ?
I would love to audition different audio equipment in my car before I install ?

In my 18 ++ years of audio installing, I have never come across any dealer like this...
Pointers would be appreciated..

Bhagwan-sab, come to Bangalore! Those who are confident about their abilities and selling acumen definitely do (unless one goes there for time pass). There are few in Bangalore.

DA, Bhagwan is an absoute mad man. The list of audio equipment he has tried is endless (and priceless) and I am sure that many of the names are new to most here. Even dealers might be unaware of the very existence of the brands Bhagwan want to audition.

Bhagwan you are an exception. No dealer is going to have Morel Supremes, Scan 9900s or Esotars available for audition. DA's commment was meant for normal folk who are looking for Pioneer/Kenwood, JBL/Infinity, Polk, Boston, etc....and not the brands you are interested in.

Hi,

Its been close to a month with the new Rockford Fosgate speakers (4" front and 6x9 rear). The vocals are very sharp and the overall clarity is a huge jump from my previous set.

Observations:

The sound on Fad:0 and Bal:0 is rear biased. Feels as if the sound is coming from the rear. Shifts to front only when Fad Fwd: 5.

Is this setting alright? Would adding an amplifier help? RMS of front speakers is 25w and rear is 50w. A saw a Sony which gave RMS 60wX4. This amp is costing around Rs.4500/-. JBL 644 is costing around Rs.7000/-.

I like the thump from the 6x9 and do not feel the need for an extra sub. So the amp for the 4 speakers only. The shop guy, also suggested a 2 channel amp, but then, wont I loose the Fader?

Please Advice.

1. if you get the 2ch amp and use the HU for the rear channels you wont loose the fader. It is just that only the front speakers will be fed via the amp.

2. F0 R0 usually gives a sound that is balanced towards the rear. This is becuase the rear speakers use the large trunk as a cabinet and hence are more efficient. Front speakers are not as efficient so need more power to produce the same sound levels.

3. With an amp you can set the gain levels to suit your preference.

Thanks Navin for such a prompt response.

So understanding you correctly, I should go for a 2 Channel amp and not a 4 channel? Connect it's two channels to the two front speakers and leave the rear speakers to be powered by the HU? Would this correct the balance and allow all the 4 speakers to play at their full potential?

Coming to the amp, Sony is what I saw and have not made up my mind on anything yet. Shops close to my home stock Sony mainly, hence got their quotes. Sony XM-GTX6022, a 2 channel Amp gives RMS 60wX2 and a JBL GT5-A402E gives 40wX2.

Coming back to a 4 channel amp for a little while. If I feed all 4 speakers by the amp, by my logic, it would make the rear speakers even louder and further the ruin the stage, right? Is Setting the gain settings similar to fading functionality?

Am open to all advices and suggestions to have a good sound stage in the car.

Nope what I said was that by correctly adjusting the gain settings on the amplifier you can make the front channels louder than the rear. This applies to either a 2 ch. amp or 4 ch. amp.

What I said was that if you only got a 2ch. amp you will still NOT loose the fader; which was an aphrehension of yours.

Given the small price difference between a 2 ch. amp and a 4 ch. amp I'd recommend a 4ch. amp.

Ahh I knew I was missing something. 4 Channel it is then. Let me research on 4 channels and come back if I have any more queries.

Thank You so much.

Mashmash, even if you are not using 4-channels. Its always best to invest in a 4-channel amp than 2-channel considering not much difference in pricing.

Those extra 2-channels may come handy when you perhaps add a woofer in future.

Btw, IMO, Sony brand is generally frowned upon when it comes to ICE.
