Just after general comments on the brands...
Rainbow is a well established brand from Germany, hand made speakers using some of the best materials available. Rainbow offers different variants of the speakers for different tastes.
Tru Technology also hand make all their amps in USA (one of the few companies to still do this), each amp is quality tested, all amps feature dual power supplies and have thermaly capable heatsinks to handle the rated power output.
There are two Rainbow CS 265ves - the Profi (silk dome tweeter and a natural fibre cone on the mid) and the Profi Vanadium ( aluminium/celulose dome tweet and woofer cone).
The Tru Tech T4.100V2 would be a good choice - you will be able to run your fronts and a sub of this amp very well and it will sound very good too!
Where are you located ?
