As mentioned above, let's see the model name / no. When trying your speakers, what were you using? ( cd/ iPod/ turntable ). Are the connector leads faulty?
The rotel mentioned , would be ok IMHO . I would say , get an amp 40 watts max ( 20 watts per channel). Something like a Cambridge audio perhaps , where you get good quality without spending bundles.
I think kiwi has an amp,for sale , which may be ideal.
Don't forget to get decent speaker cable .79'strand cable should be sufficient
