Amplified Mixer

Okay so I recently got a set of new speakers from a friend at real good price. Here are some of the important specs.
Incase you need any more info the speakers are “MTX TP212” I have two of these towers.

Configuration Passive
Power Rating 450W
Frequency Response 30 Hz – 22 kHz
Impedance 4 Ohms
Now my question is will this powered amp I found on amazon. be enough to power these speakers for house parties?

Answer #1
600W amp -> 450W speakers = you should be OK. You could go bigger if its in your budget.
Good rule of thumb is Amp Wattage should be double the rating of the speakers. The #1 reason people blow up speakers is under powering them. Amp W < Speaker W
