Hi all -
I have the Alpine PDX-V9 amp with four Polk Audio DXi650s component speakers rated for 55w at 4 ohms. The amp is rated for 100w at 4 ohms.
I know when tuning the amp you're suppose to set the amp gain to it's lowest setting and then gradually increase until the speakers begin to distort. By reducing the gain a bit, does this determine the maximum power to the speakers for maximum performance and safe operation? Or does it just mean that the speakers can handle it but after so much use they'll end up failing in little time?
