Digital Mini Series

5 Channel, 4 Channel and Mono

• Class D Digital
• 4-Way Protection
• SMD Technology
• High-level inputs with auto turn-on
• Low-level RCA inputs

Designed to work perfectly with factory speakers and head units, the new amps offer greater efficiency per Watt, and a wider range of input (.5V ~ 12V). Advanced SMT circuitry provides better current flow and reduced RF and EMI noise for less distortion and better frequency reproduction, giving you more Watts per dollar. 

Designed with custom installation in mind, these compact amps deliver incredible sound quality thanks to the Philips home audio circuitry and very low power consumption.
