Just bought a Vios will be getting it soon this coming mid-May!

I was wondering since I bought the E version without the full spec speakers.. if I were to uprade it from 4 speakers 6 speakers.

Is this possible to do so? If so what are the pros and cons and the pricing. I'm someone who appreciates music when driving.. any help will be great!

Do tweeters increase the sound quality by much at all?
I listen to alot of latest songs plus club songs... though I dont necessary need the bass to be blasting until outsiders can hear from the car like those 'clams'

Yea you're right I'm not satisfied with it at all.. the quality is poor and it doesn't even feel like it surrounds...
I don't know what to do with it, should I add just subwoofers + tweeters to give it a surround feel instead of changing the whole original system? As I feel it is a waste considering it is all still brand new lol


My Chevrolet Optra original sound system was soo much better

Grr I got a Vios E spec year 2011, very unhappy with the engine noise it makes and the wind noise when cruising on the highway... is this normal for the newer Vios? My friends 08 model engine doesn't make much noise at all compared to mine.... Anyways anyone here went to a good shop that can do good soundproofing for the wind and engine noise?
