Audio system

... Audio system is one of the most important things in a vehicle for me ..

and honestly speaking i wasnt at all impressed by the 2018 Acura RDX audio system it sounds not so good...

now to the question .. is it possible to get a third party audio system (speakers ) installed in the car without voiding warranty ? if so where do i look ..

the car has only 4k miles and is bought brand new last july so kinda worried about doing whats not soo necessary but craving for a good music system ..
