...i guess its safe to install a 35watts 8ohm speaker on a 55watt amp rated at 4ohms...because the amp will see doubled resistance (in this case 8ohms) and will cut in half its driving power to somewhat around 25watts...meaning the 35w speaker can still handle the 25w power of the amp...but in practice it's ideal to double the power rating of the speaker against the power rating of the amp.

...but according to you, there is an impedance selector on the amp..4/8/10ohm...chances are it has an impedance matching output transformer...so i guess the amp still drives at 55watts regardless of the impedance selected...

...the trick i guess is to set the amp's impedance to 4ohms...so your 35w/8ohm speaker dont get busted...i hope it helps...
