DB2.2 2/1 Channel Class AB Bridgeable Stereo 12v Power Amplifier Complete Populated PCB Assembly

World RRP: £159.99

Category: Spare Parts

Product code: DB2.2PCBA

New styling offers a modern slant on the classic DB family design – the range also includes a 4 channel and a mono as well. Most importantly, all our amplifiers are now exactly rated for power and this 2 channel model will also operate bridged to drive a modest subwoofer (external crossover required) if the need arises. High level inputs allow easy connection to most systems if RCA feeds are not available. As a unit to drive a component system, pair of co-axial speakers or other stereo requirement this is a highly suitable amplifier that offers outstanding value for money.
