NA1 Amplifiers

Big on Sound. Small on Size.
The new NA1 compact amplifiers feature a proprietary full range class D design that provides a very small footprint making these amps perfect for installation in applications where size matters. Each NA1 compact amplifier features a detachable wire harness that simplifies installation in tight spaces. Simply wire it up then plug it in! Although these amps are small in size, they’re big on power and features. There’s no shortage of controls necessary to dial your system in and there’s plenty of power on hand to satisfy the demands of nearly any speaker.
