Overview
Product Description
Big clean power and unbeatable reliability. This Ultra compact aluminum chassis amplifier with conformal coated PCB board combined with waterproof connections make this amplifier ideal for the Harley harsh condition environment. This amplifier has the perfect amount of power for Infinity and other speaker systems. Selectable internal crossovers make this the perfect amplifier for use with or without a DSP.
About Plug and play connections option
Speaker Outputs
We offer an optional plug and play configuration that terminates all speaker outputs with 4 pin Molex connectors that are plug and play with American Hard Bag and Velocity speaker wire harnesses. This is also the same Molex plug that Harley uses as the rear speaker output from the factory radio, so this connection is also compatible with any factory supplied speaker wire harness that mates with the factory radio output.
Compatible Plug & Play Speaker Wire Harnesses Required for Installation (sold separately).
VWH-FPOD Upper fairing speakers
WH-SBB2-PNP Rear speakers (lids)
VWH-4CHSBB 4 Channel rear speakers (lids with active tweeters), also compatible with Velocity 8 DSP
VWH-TPSBB 4 Channel rear speakers (tour pack with active tweeters), also compatible with Velocity 8 DSP
Power Input
The plug & play option also comes with an Anderson power pole service disconnect that is directly compatible with our Premium Velocity power harnesses VWH-8G (sold separately). This give you a serviceable connection in the fairing, which makes everything so much nicer to deal with in there.
Remote Turn On Input
We also terminate the remote input so that it is plug & play with the factory Harley accessory circuit in the fairing as well as all American Hard Bag, Musway, and Velocity DSP remote output harnesses.
With the plug & play option it is entirely possible to do a complete amplifier installation without ever cutting a single wire.
