Hi My name is Carlos and I hope you can help me. I just bought an amp 1400w MACKIE FR-400@ 4 Ohms bridged and 2 speakers PROpower ppa5812 500W 8 Ohms . Last week we had a party and in the middle the speakers failure. I just want to know if the power for the speakers(500w) is to high for the amp? the speakers do not work anymore. I need to buy another pair. should I buy say with 300 or lest watts?
