Hello Gurus,
Its been 2 months I have my UVA and I am trying to enjoy it, but feels like I need something more.
Info on current ICE
Head Unit - WX-VX555 (installed through dealer as wife liked the looks

.) I will not change this.
Speakers Front - Sony CRAP series - Big, Location - Default (Front doors)
Speakers rear - Sony CRAP series - real small, Location - Default (under the plastic grill near rear parcel tray)
What I want
1. Good set of front speakers at default location - Need to be crisp on vocals (Hell freezes over should be able to freeze my blood, Justine timberlake should sound as soft as he sings) - 5K
2. Good set of Rear speakers at default location - I am doubtful if I can get these. - 3K (well size is smaller

)
3. Mono Amp - for Base tube (no preference) - 5K
4. Base Tube - 10" or 12" (should be removable incase I plan to use entire boot). Not reallt impressed with the space the sub enclosure occupies. - 5 to 7K
5. 4 Channel Amp - This depends on the reliability of the installer. - 7 to 8K
6. Cables would be suggested by you guys or the installer.
All above are driven by budget of 30K. If I can reduce and get something good, I am ok with that. I want the ICE to be SST (Sasta Sundar Tikau). This is the slang we used in college and in early career years. What I mean is Value than the Brand.
My Queries
1. Can I do all above at a good installer without introducing any rattles?
2. Place in Mumbai where I can get this done? Are there any professionals available?
3. Will this affect anyways to the cashless ownership or warranty?
