🔊 Excellent configuration flexibility

1️⃣ Powering two pairs of speakers

With separate high-pass crossovers (HPF) for channels 1-2 and 3-4, the amplifier effectively eliminates the lowest frequencies that stress the speakers. The result is a cleaner, more dynamic, and more articulate sound, even at high volume levels.

2️⃣ Powering one pair of speakers and a subwoofer

The amplifier can be configured to power two channels of the front speakers, and the remaining two, when bridged, power the subwoofer.
HPF and LPF crossovers allow for perfect frequency matching between the two sections, ensuring a coherent, dynamic sound throughout the system.
The wired bass controller allows you to precisely control the bass level from the driver's seat—without having to adjust the amplifier settings.

🔋 Safe and reliable operation
