Product Details

When integrating with factory fitted multi-speaker systems this add on is a must for expanding the capabilities of Prima bit amplifiers. Sharing the same footprint, up to three Prima amplifiers can be stacked for maximum space efficiency without over heating. Alternatively you can use the AP 4D with a standalone processor such as Audison bit One or bit TenD.
