Designed AND Built Specifically for Motorcycles

Cicada Audio was started to develop a product SPECIFICALLY for Harley-Davidsons and other motorcycles. Even though you?ve probably never heard of Cicada Audio?.our president and head engineer has been designing 12V audio for over 30 years. He has 5 design and engineering awards and 2 design patents. He?s developed 1,000?s of products in that time, many gaining ?cult? status. He REALLY knows 12-volt audio. He saw that there was a real need for some new thinking and new direction in audio. Specifically ?motorcycle audio?. We, at Cicada Audio, don?t do Car audio, we don?t do Marine, we don?t do ?Powersport? audio. We ONLY do Motorcycle audio?PERIOD!@!!

CICADA AUDIO ? The ?New Kids? on the block

It?s fitting that the SECOND amplifier we deliver will be an ultra-compact aluminum chassis, the CX125.4 amplifier is element-ready, being the ideal choice for Motorcycle installations. It features an incredible power/size ratio and an easy setup. HighPass and LowPass Crossover slopes are 12dB per octave and adjustable from 40-400Hz. Input sensitivity is adjustable from 0.2Vac ? 12Vac. Making it possible to connect to a high-power HD radio without ANY line output converters involved. For your motorcycle, this amplifier is the perfect size and power (especially with our 2-ohm Co-Ax Horn speakers) to get you the most output, power, and clarity possible. Everything to make it that it is easier to set up the audio on your bike. Quickly. We think you will be happier than hell to finally have an easy solution to a DIY audio system for your HD. Also, look in our accessory section and see all the harnesses available to make life a WHOLE lot easier for you. Plug and play baby!!!

Fitment notes: This amplifier is a great ?form factor? as it can sit on top of the radio or under the left/right bike fairing substructure. Easily fits into the fairing of any Harley Bagger 1998 ? 2019.
