The XL series was developed for the growing Power Sports market including UTV and Marine applications, where electronics must withstand harsh damp environments. The circuit boards have been conformal coated with a layer of transparent material that protects the parts against moisture, dust and extreme temperatures. While the harsh environments can leave electronics in situations that water and extreme dust is a factor, the new XL-MX series amplifiers have been designed to remain completely sealed with an IPX67 Water Resistance Rating ensuring your amplifier stays dry even when your ride leaves you all wet.
