href=\"\/products\/cicada-audio-flx500-4-4-channel-class-d-motorcycle-amplifier\"\u003eFLX500.4\u003c\/a\u003e is a 4-channel Class-D amplifier designed for Harley-Davidson® Touring fairing installations. In the 14FLXCXX-4X2, it runs in bridged mode — pairing channels 1 and 2 to drive the left \u003ca href=\"\/products\/cicada-audio-cxx65-4-motorcycle-coaxial-speakers\"\u003eCXX65.4\u003c\/a\u003e, and channels 3 and 4 to drive the right CXX65.4. Bridged into the 4Ω load of the CXX65.4, the amp delivers approximately 250W per speaker — double the output of the standard unbridged configuration. \u003cem\u003eOn the road: the bridged FLX500.4 delivers noticeably more headroom at highway speed. With pipes and wind in the mix, the increased output keeps the front stage projecting clearly without the amp being pushed into its upper limits. The difference is audible at volume.\u003c\/em\u003e\u003c\/p\u003e\n\u003ch3\u003eThe CXX65.4 Speakers\u003c\/h3\u003e\n\u003cp\u003eThe \u003ca href=\"\/products\/cicada-audio-cxx65-4-motorcycle-coaxial-speakers\"\u003eCXX65.4\u003c\/a\u003e is Cicada Audio's 6.5″ Pro Coaxial speaker at 4Ω — the correct impedance for this bridged application. The carbon matrix cone is stiffer and lighter than IMPP, maintaining linear excursion at higher output levels and reducing cone flex that bleeds power into heat rather than sound. The voice coil is wound for higher sensitivity — more acoustic output per watt of amplifier input. \u003cem\u003eOn the road: the CXX65.4 projects vocals and midrange with more authority from the fairing position. At highway speed, where the standard CX series starts to lose intelligibility in the wind, the CXX maintains clarity further up the volume curve. Paired with approximately 250W of bridged output, the Pro Coaxials reach volume levels that remain useful well above 60 mph.\u003c\/em\u003e\u003c\/p\u003e\n\u003ch3\u003eWhy 8 AWG Wiring\u003c\/h3\u003e\n\u003cp\u003eThe \u003ca href=\"\/products\/cicada-audio-hdpg8k-harley-power-ground-kit\"\u003eHDPG8K\u003c\/a\u003e 8 AWG power and ground kit is correctly matched to the FLX500.4's current draw profile — even in bridged mode, a 500W Class-D amplifier at music-level signal demand draws well within 8 AWG capacity. Running 4 AWG wiring on a system that doesn't require it adds cost and installation complexity without benefit. \u003cem\u003eOn the road: no voltage drop, no thermal stress on the wiring, no need to return to the install to address an undersized supply. The HDPG8K is sized for this system and does the job cleanly.\u003c\/em\u003e\u003c\/p\u003e\n\u003ch3\u003eRadio Flash — Required Before Installation\u003c\/h3\u003e\n\u003cp\u003eThe 2014–2023 Harley-Davidson® Infotainment radio ships from the factory with firmware tuned around the stock speaker system. That firmware applies significant EQ curves to compensate for the limitations of factory speakers, dynamic compression to manage volume levels, bass roll-off as volume climbs, and output limiting that caps usable signal before the amplifier can act on it properly. None of this is removed when you add an amplifier — the processed, limited signal goes into the FLX500.4's input exactly as it came out of the head unit.\u003c\/p\u003e\n\u003cp\u003eThe result without a flash: the FLX500.4 amplifies a signal that has already been compressed, EQ-adjusted, and capped. Bass collapses at highway volume, midrange sounds congested, and the system runs out of headroom well before the amplifier's rated output. \u003cem\u003eOn the road: the performance gap between a flashed and unflashed Harley radio on this install is not subtle — it is the difference between the system working and the system not working.\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003eWith a flash, the EQ curves, compression, and limiters are removed. The radio sends a clean, unprocessed signal to the amplifier, and the FLX500.4 operates on signal it can actually work with. A radio flash takes approximately 30 minutes and costs around $150–$300 AUD depending on provider. TechnoResearch is the most widely used flash service for this application; any authorised Harley-Davidson® dealer with Screamin' Eagle® Flash tooling can also perform the service.
