*1: Do not install the unit in a spot exposed to direct sunlight or excessive heat or humidity. Also avoid places with too much dust or the possibility of water splashing.


Many of today’s powersports have very limited space to work in and tend to be a harsh environment for electronics because of the exposure to outdoor environments. KENWOOD’s compact performance amplifiers are small in size so they fit even the most limited installation areas. The amplifiers also use a conformal coated main PCB (printed circuit boards) which offer extra layers of protection to help prevent moisture or damp air from damaging the product.
