PowerBass XL-4255MX 1000 Watt RMS 4ch PowerSport Amplifier 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. These ultra small weather resistant amplifiers are ideal for all types of outdoor audio applications such as motorcycles, golf carts and off road vehicles. But the small size also makes these amps a great choice anywhere space is a premium.
