Audison Prima AP8.9 bit
This extremely versatile plug and play amplifier will set your speakers free from the constraints of vehicle manufacturers sound curves. 8-channels and Bit technology in a very compact case. Following a lengthy and comprehensive development programme, the Audison AP8.9 Bit amplifier offers fabulous sound enhancement for multi-speaker amplified factory car audio systems. Research revealed that many car speakers are not driven with enough power to offer the control required for a car speaker system. Furthermore, distortion rapidly increases to unpleasant levels when the volume is turned up. The clean signal handling of the eight class D channels and the incredible signal processing power overcomes many of the stock issues.
