Intresting thread,
Rear Components mount where and how?
Im thinking woofer in the door panels and tweeters on either the B pillars or the C pillars.

Why do you want components in the rear?

Often the rear components mess up the sound stage for the front passengers because the rear tweeter is closer to the ear of the front passenger than the front tweeter is.

Just a thought.

Have two questions before we can get to the placement of speakers at the rear:

1. Do you have a chauffeur to do the driving duties or you do it yourself?
   
   
2. Are the rear seats occupied always and are they not finding the sound stage good as when seated at the front?

As rightly said by Navin sir, adding components at the rear will disturb the sound stage unless the prime listener is seated at the rear always and wants the sound "tuned" to his/her seating position.

To answer the question, the woofer can be mounted on the parcel tray after damping the metal underneath and tweeters can be mounted near the woofer itself or the C-pillar if angled and installed correctly. See the image below taken from the Rainbow's Speaker installation manual:



What I'll suggest is, get components at the front, coaxials at the rear and add a DSP that will let you do the "Time Alignment", fine tuning etc. With the DSP in the sound chain placed between the 'source unit' and the 'amplifier', you can have a number of presets where you can fine tune the sound stage to your requirement.

For Eg:
Preset 1: Sound stage primarily for the driver
Preset 2: Sound stage primarily for the rear passengers and so on.

By this, you can save on installation costs (to some extent) and prevent cutting into plastic panels (read tweeter installation).

I took delivery of Mahindra XUV 300 a week ago and the sound quality of OE speakers was terrible. I went to Mahindra to install rear-view camera where I saw a range of brochures to upgrade speakers.The exec quoted 4k for Infinity Primus co-axial 6.5 inchs and I immediately went ahead.

Initial impressions
The sound quality is definitely improved but not as great as I would have liked.I have a couple of questions for my fellow BHPians


1.Do the speakers need to "break in" before they can produce optimum sound? if yes then for how long do I need to break in?



2.What are my options to further improve the output? I have no plans to install a sub-woofer and amplifier. Should I get Infinity components in the front and move the co-axials to the back?

Stock head unit output is generally not great, getting a amplifier helps. Even adds the ability to better position your sound. Upgrading two out of four generally will require you to tweak the equalizer for the different sets differently. The stock unit has heavy equalization built in. Changing it gives best results, but adding a good amp also works.

Components helps create a better sound stage and improve the overall quality. However if u don't have components from factory, make sure they are positioned correctly while installation.

Having damped doors always helps reduce unwanted resonance and vibrations. Damping is one of the most important thing, that we tend to ignore. Damping is not cheap either.

And I forgot to mention, Components need a lot more power generally, so an amp is advised with install.

Yes, I have heard from many good installers that speakers have a break-in period. Even I am not aware of the exact timeframe but you can give them a couple of weeks (10-15 days) to see if the sound improves.

That said, do not have much expectations from coaxials. They will sound better than stock speakers but not in the league of components.

Should I get Infinity components in the front and move the co-axials to the back?

Generally, anything over stock will sound better. If you have auditioned Infinity components and liked them, you can put them in front and move coaxials to the back. If not satisfied with output, you can then add an external amplifier at a later stage to power the speakers (even if you don't want a subwoofer). Stock speakers in Mahindra cars are very low quality. I think a complete speaker upgrade (even without amp) will improve sound quality considerably.

So, I went ahead and got JBL CS-760CSI 6.5 Inches components installed in front and moved the Infinity Primus to the back, gave all 4 stock speakers to my security

Installation done by Mahindra authorised service center to retain standard warranty.

Now, I feel the vocals clarity has improved a lot but not satisfied with bass. Its below par in my opinion.

I am a novice here so please help me with two questions.

1.Comps are good only when paired with an Amp and Sub and cannot sound good by themselves?

2.Or should I get it checked by an expert audio shop to see whether the crossover setting can be fiddled to improve sound output?

Did you replace the Infinity Primus 6500 with the JBL CS 760? The former has a more laid back treble response and a more defined bass response. I would suggest using the Primus in the front and the JBL in the rear.

Some components prefer an amplifier as they are inefficient. The JBLs are happy even without an amplifier, the Primus however would be more demanding of an amplifier.

Yes, I did that! Thought a JBL comp would be better job in front( there is a provision in XUV 300 front door only to affix a tweeter) than a Primus Co-ax.

I am really confused what to do now? By the way what are your thoughts on the JBL CS 760 comps.


I cant put an aftermarket Amp as that would void the warranty.

The Infinity Primus CS 6500 is a component system not a coax. Now I am confused. Which Infinity Primus speakers have you replaced with the JBL?

This is what the CS6500 / 6510 look like.

JBLs as a rule tend to be brighter than similar Infinity models.

Then you should have looked at fitting the same brand of components. Now that you have the JBLs my best advice is that you consider using the equaliser settings on the head unit to reduce the high frequencies and boosting the mid-bass.

Thankyou so much for your suggestion. I tried to change EQ settings and have got excellent results so far. Earlier almost all frequencies were set to +8 level, resulting in average sound quality.

The present settings are exactly as per image.

The bass is way more than what it was, vocal clarity is excellent but I think I can fine tune it even better.Please guide me on how it can be improved further.

Reduce the bass.

I would start with a flat response and then add or cut the 5 bands that you have by ear.

Probably the answer to the question still awaits. I have a 2019 Ford Figo S with an Infinity Primus components fitted at the front. I have damped all 4 doors (internal and external) Tomorrow I am heading to the same shop to install Primus components in the rear and add a sony xplode 4 channel amplifier. Need help on the below:

1. Best placement for rear tweeters (most times it is only me in the driver seat & dont like the tweeters to be close to my ears at the rear)

2. Is there any specific amplifier settings to be done?
