Carson HPK-150 Under Hood Waterproof Stutter Horn System


The HPK-150 Under Hood Stutter Horn System offers the same loud and legal* features and functionality as the HPK-100 In-Cab Stutter Horn System, but utilizes the HA-150 Under Hood Stutter Horn Amp for exterior, all-weather installations. The HPK-150's ultra-compact component design and waterproof amplifier provides versatile, "under-the-hood" installation options for any volunteer POV, motorcycle, ATV, or marine craft.
