NA2 Amplifiers

  • Powersports Amplifiers
Big on Sound. Small on Size.
The NA2 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 NA2 compact amplifier features a detachable wire harness that simplifies installation. Simply wire it up then plug it in!

Although these amps are small in size, they’re big on power (2 ohm stable). When it comes to features there is 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.

The NA2 series also offers a 5 channel amplifiers (NA2-500.5) which offers a very simple system solution which allows four full range speakers or tower speakers to be run off the four full range channels. Then, the 5th channel is left to power only the subwoofer. This creates a very simple, compact, yet power installation.
