What to do about my quiet satellite speakers?

[Shay HTFC]

I have some satellite speakers plugged directly into my laptop (using an adapter that takes the L/R cables and converts them to fit in the laptop's headphone socket)

They have no separate volume control or power supply and I was wondering if its possible to buy some sort of booster that sits between the speakers and the laptop to boost the volume a bit.
Max volume on the laptop is still relatively quiet compared to how powerful the speakers look.

Anyone got any ideas? (I don't want to have to get the central subwoofer sound system if possible)

The headphone socket is designed to power headphones so has a very low output, I suggest you just get some powered PC speakers, you can buy some for £10.
