It also covers a bike that had factory Boom!™ amplification, where the Hertz is going in to replace that amplifier outright – depending on how your bike is wired that may need a factory amp bypass harness as well, so call us on 07 3350 1354 before ordering if that is your build.\u003c\/p\u003e\n\n\u003ch3\u003eWhat This Is Best For\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBuilt for the Hertz SP series\u003c\/strong\u003e – the amplifier end is terminated for the SP-series input, so it drops straight onto a \u003ca href=\"\/products\/hertz-sp-4-500-4-channel-class-d-amplifier-harley\"\u003eHertz SP 4.500\u003c\/a\u003e or \u003ca href=\"\/products\/hertz-sp-4-900-4-channel-high-power-amplifier-harley\"\u003eSP 4.900\u003c\/a\u003e without hand-wiring the input plug.
