Audio upgrade options for a Toyota Hyryder / Maruti Grand Vitara

Due to compromised boot space, I don't want to go for a subwoofer.

BHPian OpenRoads recently shared this with other enthusiasts.

Hi all,

I am trying to gather some information for an audio upgrade for the Toyota Hyryder. Please let me know your thoughts.

I am looking for an amplifier with an inbuilt DSP (to minimize the overall footprint). Based on my research, I found a few of them but I don't know which one would be the right one. They seem to be within budget but not sure if they would be compatible with the OEM head unit of the car which I do not wish to change:

1. Alpine PXE-R500 (does it even have a DSP?)
2. Sony XM-GS6DSP (is it too old?)
3. Kicker 47KEY200.4 (do you even get it in India?)

Is there any other model that I should consider?

Second, I would like to go for door-damping. Again, there are so many types of sheets based on brands and thickness levels. Which one should I pick? Any suggestions? Also, is a layer or two is sufficient?

Third, speaker setup. Currently, there are four speakers and two tweeters which is the default one. Hyryder does not have a subwoofer. And I don't want to disturb this setup. I love to hear music but don't want it loud. Clear vocals are good enough for me. So the question is if I can keep the speakers a little longer or should upgrade them? If yes, then what kind of speakers should I be looking for?

e.g. Focal ASE 165 or something similar.

Fourth, due to compromised boot space, I don't want to go for a subwoofer. Will that be a dealbreaker? If yes, what should be considered?

Update: I got some more updates talking to a few installers in my town. Here is an update on that.

Amplifier/DSP choice:

1. SoundMagus MP6 MAX [50W RMS/channel] quoted around 35K
2. Alpine PXE R-500 [25W RMS/channel with peak at 50W] quoted around 30K

Speakers:

1. Focal Auditor 165 ASE (front)/ACX (rear) should be max 15K
2. Focal Access 165 AS (front)/AC (rear) should be max 28K

Now both these speakers have 60W RMS with a peak of 120W. I am worried if the Alpine is even the right fit here.

Sound deadening/damping:

• 2-layer damping with Morel 2.1mm (10 sheets) is quoted around 10K.

Subwoofer:

• I am looking for one with a 4 Ohms impedance and low RMS (50W) but it is hard to find. If I go any higher I might need a separate mono block which I don't want. So I might give that a miss.

Bottomline: The Alpine seems to be a good fit if the speaker RMS is not an issue. I am searching for answers to this one. Will keep everyone posted on what I find.
