audio upgrade

[rob72]

looking to upgrade the standard sound system on my ph1 172.
ive already replaced the 4 basic speakers with infinity custom fit things that i stole off my gf,s clio.. (she never even noticed).
this improved the sound a good bit but not enuf for my liking.

question is, whats the next step for improvements with a budget of £300.
