Im wondering if anything (non drastic) can be done to slightly enhance the sound quality of the stereo.

I have the standard speakers with the radio/CD player.

Is it worth considering an amplifier?

Does anyone have experience when it comes to this?

Try posting in the ICE section. Will get a better reply.
Only way to improve sound will be to replace your HU, and/or speakers. An amplifier will only send a bigger signal, making it louder... Will not make it sound better, but more likely worse as the speakers are being over powered with the larger signal...
