Rear Y-adaptor for bridging a Cicada Audio® DSP600.4D or CX600.4D as a second amp from the H-D® factory rear radio output. Molex® connectors, plug-and-play.
The Cicada Audio HDRiMY is a rear input Y-adaptor for bridging a Cicada Audio DSP600.4D or CX600.4D amplifier from the H-D factory rear radio output – provides the bridged signal configuration needed to run the second or bag amplifier in bridged mode using the factory rear channel signal. Plug-and-play, no cutting or splicing required. Note: requires the 4-channel output plug and appropriate output harness to be present on the factory H-D radio.
Running a second Cicada Audio amplifier in bridged mode off the H-D factory rear radio output requires the signal to be correctly configured for bridge operation at the amp's input. The HDRiMY provides that – taking the factory rear radio output and delivering it in the Y-adaptor configuration the DSP600.4D or CX600.4D needs to operate in bridged mode for rear or bag speaker duties.
Who This Is For
Builders running a Cicada Audio DSP600.4D or CX600.4D as a second or bag amplifier in bridged mode, driven from the H-D factory rear radio output. For a standard (non-bridged) rear input harness, see the HDRiM. For the front bridged Y-adaptor, see the HDFiMY.
What This Is Best For
- Bridged-mode operation for a second/bag Cicada amp – provides the rear Y-adaptor configuration required to bridge a Cicada Audio DSP600.4D or CX600.4D from the H-D factory rear radio output.
- Plug-and-play installation – Molex connectors throughout; no cutting or splicing to the factory harness required.
- Multi-amp system integration – enables a dedicated rear/bag amp to run in bridged mode alongside a front fairing amplifier, driven cleanly from the factory rear radio signal.
What's Inside the HDRiMY
The adaptor is a Molex-connectored link with the Y configuration built into it: it takes the factory rear radio output and presents it to the amplifier input in the bridged arrangement a DSP600.4D or CX600.4D needs for rear or bag duties. It plugs in at both ends, with no cutting or splicing. On the road: the factory harness stays uncut, so the wiring behind the panels is the wiring the bike came with.
Because the signal is taken off the rear channel, the bridged amp sits alongside a front amplifier instead of replacing it. On the road: the second amplifier runs the rear speakers while the front amplifier keeps the fairing, so each end of the bike has its own output behind it.
