Recommend a Mini Hi-Fi System?

[Magenta Sunset]

There isn't a Richer Sounds round here so that's out lol, closest one is Norwich.

Had already looked at the Argos ones, same as the Currys ones lol.  The couple that fit my criteria only have 10W speakers, that doesn't like much compared when standard car speakers are more than double that??  Or will that be fine due to the different environment (less external noise)?

depends if they're quoting RMS or 'Music'(PMPO) output
