Advice on chevrolet matiz sound system?

Hey guys! Right, I'm a girl and I haven't got a clue about these kind of things. I have a 2008 chevrolet matiz and I'm very unhappy with the sound system, the actual cd/radio player is fine but the bass is TERRIBLE! What do I do? Get new speakers? Bass box? Please help! I would like advice and sucess stories!


Also; the sound is tinny and when turned up the bass becomes muffled...

HELP! What would you do if you was me and please remember I'm a girl LOL.


Thank you
