Why Choose This Product?
The DIA-3550.1D gives you three stated RMS output levels across 1-, 2-, and 4-ohm loads, making impedance and power matching central to choosing your setup. Its adjustable filters and bass boost provide settings to work with as you configure the system, while the remote bass-level controller puts level adjustment within reach.
Note that 3550 watts is the maximum power rating, not the continuous RMS output. Use the RMS rating for the matching load when comparing amplifier output with your subwoofer’s power handling.
Installation & Compatibility Notes
Match the subwoofer impedance and power handling to the amplifier’s output rating before installation. Use appropriate power wiring and fusing, and allow for ventilation. The amplifier measures 251.2 × 140 × 48.3 mm; check available mounting space before fitting it.
