Factory Bose speaker system is just fine for both of us. Wife commented that she really likes it, who is the major driver and always has it cranked up to her favorite local FM music station. Whenever I have an opportunity to drive and alone, the sound from my recorded CD's is music to my ears. We have our sound adjustments to where we both like and don't have to keep readjusting. Classical Music, which is the real test for any system, is superb listening through this factory Bose System, in MY opinion.
