Question type: Car Customization

I want to upgrade the factory sound system .It sounds very "thin" currently.My budget  is limited.Would a powerful
amplifier improve the depth and overall performance?
Also,the Sirius radio has a background hissy like distortion like its slightly out of phase.Anyone know why and how
to rectify this?
Thanks
