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.
"Perfect little amplifier that have 8 channels with subwoofer separate connection. Well balance sound output. Reasonable price. Fit perfect On the hidden side channelsOnly trouble is how much will it pull car battery."
"Had this unit fitted and set up by Autosounds in Newcastle along with all the OE speakers replaced by Audison ones. My Z4 sounds awesome, utilising the full extent of the AP8.9bit has transformed the listening experience, a worthwhile upgrade. Thanks to Autosounds and all the team at Audison !"
"Doesn't seem too powerful enough"
"Excellent unit superb sound."
"Great product that could be improved with accessibility the only issue. It should have Bluetooth with an app that will support adjustments, not solely relying on a PC interface to make changes."
"I had a standard 6 speaker system and standard head unit in my BMW and was unhappy with the sound quality. After upgrading my speakers and further research, I opted for the Audison Prima 8.9 bit. The sound quality is significantly improved and has much clearer definition and clarity, as well as overall power. I would recommend the Audison over standard stock unit and the other advantage is that it is designed as OEM integration so can be easily removed and fitted to any future car."
