Hi newbie here, need more info and advice. I plan to purchase morel tempo ultra 602. As I check the RMS speaker is 120watt and max is 250watt.

My concern now which 4channel amplifier is suitable for it.

Do I need to search 4ohm 120watt to match the speaker RMS 120.
Coz outside market I search to get 120 or 110 watt amp quite expensive. Lot of outside market is like 75/90 watt unless bridge only able to meet the spec 120 to 250 max.

What if I used 75/90 watt to support 120 watt speaker, that does mean under power ??

Thank you for your time to read n hope u able understand my question.
Thank in advance for your advice and information.
