An amplifier with 500 Watts RMS should have at least 20-30% margin to avoid clipping and overheating. Also essential is the correct setting of low-pass filters (e.g., 80 Hz or 100 Hz) for clean transitions to the front system. The same applies to the high-pass filters of the speakers, usually between 60 and 80 Hz. For the finest sound adjustment, an external DSP (e.g., 8-channel DSP) or an integrated DSP amplifier can be used.
