hi! the audio system that came with the 2004 rav 4 (alpine) is mediocre at best. it's like the speakers are made of cheap paper. can someone help me upgrade? i'm not an audiophile but i like my audio system to come up with music where i can hear the Ts and Ps pronounced yung parang crisp and clear. i'm not into super loud music and i need a place that can do the installation, etc. Also, preferably a system where i can plug in an ipod. Budget is about 30k? 50k max thanks!
