ATV420 V2 4-Channel UTV/Motorcycle Bluetooth Amplifier IP65 Micro Amp

The Rockville ATV420 V2 is a 4-channel micro amplifier built for ATVs, UTVs, and motorcycles that need real power in a small, waterproof package. It delivers 500W RMS at 2 ohms (125W x 4) and 2,000W peak through a Class D topology that fits into an 8.66" x 3.74" x 1.73" chassis. An IP65 waterproof rating means sealed inputs, conformal-coated circuit boards, and anti-rust materials protect the electronics from direct water spray, trail mud, and post-ride washdowns.

Built-in Bluetooth with auto pairing lets you stream music from your phone without installing a head unit or controller, keeping the setup compact. For vehicles that already have a head unit, high-level speaker inputs and waterproof-sheathed RCA inputs give you two wiring options. Independent crossover controls for channels 1-2 and 3-4 (LP, HP, or full-range, 32Hz to 320Hz) let you run mids and highs on one pair and subwoofers or bass-heavy speakers on the other. A 2CH/4CH input mode selector means you can still get 4-channel output from a 2-channel source. At 4 ohms bridged, the amp puts out 250W x 2 for dedicated subwoofer channels. For riders and off-roaders who want loud, clear audio without a complicated install, the ATV420 V2 checks the key boxes: power, durability, Bluetooth, and a footprint that fits tight spaces.
