Hi, advice needed from the Gurus to upgrade ICE in my vehicle.
Existing Stock Setup:- Nippon head unit, Speakers Front 6.5" & Rear 6" range maybe around 30-40 watt RMS from Onkyo. To be fair to Mahindra, the current setup is decent though basic and is more than enough for people who are just want to listen to Radio or other music at a low-mid level sound. But for those who want more,.... to listen to what the sound engineer at the recording studio wanted them to hear, then its time to upgrade.
Expected Setup:-
Retain the stock head unit as replacing it may hamper certain issues like navigation, etc and also face issues with ECU mapping.
Front speakers 6.5" component with a range of 40-100 watts RMS @ 4 ohm.
Rear speaker Coaxial 2-5 way 40-1000 watts RMS range @ 4 ohm. Not looking at putting speakers into boxes as it takes up space and also not in middle doors as provision not suitable due to placement or window glass movement,etc.
Option 1. 6" speakers to ready fit the slots at tailgate as no modification needed. Existing speaker grills can be retained.
Option 2. 6.5" speakers, a little modification of filing of existing slot or/and additional ring to be added. Grills need to be replaced with 6.5". Result better output than 6".
Option 3. 6"*9" More modifications needed, i.e. metal of tailgate to be cut to accommodate the speakers into the tailgate. Best output expected in this setup.
Amplifier
Option 1. prefer a 5 channel with range 40-100 watts RMS @ 4 ohm to suit the exact range of speakers, while the 5th channel required range would be 200-400 watts RMS for Subwoofer 4ohm Single voice coil.
Option 2. 4 channel AB class to power speakers and a mono D class to power the subwoofer. This option will cost more and will need more space to accommodate the 2 amps, but will result in the best audio output.
Option 3. 4 channel amp to power front & rear speakers and a powered subwoofer to save space. Costwise expensive than option 1, output of subwoofer will be less than option 1 & 2, while positive is you can save space.
Subwoofer in a enclosed box 200-400 watts @ 4 ohm single voice coil.
After visit to some after market shops noticed the following:-
Best to retain the nippon head unit as replacement will effect navigation, integration of controls of unit to steering wheel, mapping issues to ECU, etc. Big disadvantage was the stock head unit has no RCA output, so will not be able to have a audio setup with an amp that will power all 4 speakers and subwoofer. Left only with the following options:-
Option 1. Add a 4 channel amplifier to power the 4 speakers with no subwoofer.
Option 2. Add a 4 channel amplifier to power the front components and subwoofer, power the rear coaxials directly from the head unit. This option felt a better compromise.
Front speakers to be changed to components with size range 6.5" (no modifications needed as will fit stock slot provided in front door, and tweeter to be added on sail panel or on the A pillar) or with 6.75" size speakers (filling required at slot and a ring to added to accommodate 6.75"speakers).
Rear speakers coaxial with size range from 6" to 6.5" to 6.75" or even 6"*9".
Amplifier 4 channel.
Subwoofer in box to be placed in gap between the behind of middle row seat and 2 side facing seats at trunk.
