AoA Ali, congrats on the new ride. I'll just share my 2 cents since I own the same vehicle
Upgrading the audio setup will change the way you like travelling in this car. If your car has the original automate headunit, it's possibly the worst product in terms of audio output that is made by these geniuses at automate. Simply change the headunit, move the front speakers to the back (incase you want to stick to those even though there are great options of coaxials in the market) and put some nice components (or coaxials in the front). A pioneer headunit will really make your speakers sound nice even without an amp so keep that in mind. You can check out my alto build log. I also currently have a full setup pulled out of a swift which is in excellent condition including a pioneer headunit, recoil front components, recoil coaxials, pioneer under seat sub, all the necessary wiring (including the plug and play pioneer wiring harness for suzuki's and the speaker brackets. You are more than welcome to check my Alto if you are islamabad based
If you've bought the car second hand and it's not under warranty, get the sound proofing done. This car is resonating box of ****. There is ZERO kind of insulation in the doors, roof, trunk, boot or floor. Remember, adding CLD sheets (Also called sound deadening sheets locally) will eliminate the metal from resonating. That will, to an extent, make the cabin quite simply due to no unwanted noises coming from your body panels resonating. Adding an additional layering such as CCF/OCF will further block/absorb those ambient noises coming into the cabin. This will make your cabin a much better place to be in
A multimedia steering can be installed for around 8-12k. It's a personal choice but you keep your eyes on the road. And upgrading the headlight bulbs is a great way to improve your safety during night driving. I'm running Novsights in all my cars and they are great with excellent cutoff preventing any glare for oncoming traffic
