Description
For your convenience, we offer this amplifier pre-wired for factory Harley radios (flash required), as well as the Soundstream HDHU14+, HDHU14.si, and V2 models
We have completed all the hard work for you, making this a true plug and play setup! We have pre-set the gains and high pass filters to exactly what they need to be for the radio you have! We’ve also connected the power and ground wires, so all you have to do is plug into the radio harness and run the power and ground wires to your battery, then your system will be rockin’!
