SKU: C2C90
90° USB-C waterproof extension kit for Cicada Audio DSP processors — keeps the tuning port reachable in tight fairing and under-seat mounts
The Cicada Audio C2C90 is a USB-C extension and adapter kit for Cicada Audio DSP products — a 900mm (3 ft) waterproof USB-C male-to-female extension, a 1.8m (6 ft) USB-C to USB-A data cable, and a 90° USB-C adapter for tight-clearance installations. Everything needed to reach a hidden processor with a laptop, without pulling panels or putting load on the port.
A DSP is almost always mounted somewhere nobody has to look at it — inside a fairing, under the seat, behind a saddlebag liner. That is the right place for the processor and the wrong place for a USB port. A cable plugged in straight has nowhere to go and bends hard against the connector, and over a season of vibration that is how ports fail. The C2C90 deals with both halves of the problem: the 90° adapter turns the cable flat against the mounting surface, and the 900mm waterproof extension moves the connection point somewhere you can actually reach. Where the C2C terminates in a permanent cockpit mount at the cigarette / 12V lighter opening, the C2C90 is the flexible-routing version for installs where a fixed mounting point is not the answer.
Who This Is For
Builders running a Cicada Audio DSP88v2 or DSP412PRO, or a DSP amplifier such as the FLX700.4PRO or FLX1400.4PRO, where the processor sits somewhere the USB port cannot be reached comfortably — or cannot be reached at all without removing a panel. If you would rather terminate the connection permanently in the cockpit at the 12V lighter opening, order the C2C instead. The C2C90 is the kit for builds where clearance at the DSP is the constraint, where the cable has to turn the moment it leaves the port, or where you want to choose the position of the accessible end rather than commit it to the lighter opening.
What This Is Best For
- DSPs in tight or enclosed mounting positions — the 90° adapter redirects the cable so it lies flat against the mounting surface instead of standing proud of it. Inside a fairing cavity or behind an amplifier rack, that difference is often what decides whether the panel closes at all.
- Taking the mechanical load off the connector — a USB-C port is a surface-mount part on a circuit board, and a cable levering against it under vibration applies a load the port was never designed to carry. Turning the exit angle and terminating the run in a fixed extension puts the flex in the cable instead of the solder joints.
- Waterproof routing through fairings and bag spaces — the 900mm extension is rated for moisture exposure, so it can run through a fairing cavity or saddlebag space where condensation and road spray are a normal condition rather than an exception.
- Tuning with the laptop on the pillion — the 1.8m USB-C to USB-A cable reaches a laptop sitting on the seat or a bench beside the bike without pulling the extension taut, so nothing is under tension while you are setting crossovers, levels and time alignment.
- Systems that get retuned — a system tuned once and never touched again is rare. When speakers, an amplifier or the rider's preference change, either the DSP comes back out or the port is already reachable. This kit is the difference between a ten-minute adjustment and a panels-off job.
C2C or C2C90 — which extension kit
Both extend the USB-C connection from a hidden DSP, and the choice is about how the connection terminates. The C2C is a 1.8m (6 ft) waterproof extension supplied with a bracket that mounts in the cigarette / 12V lighter opening — choose it when you want a permanent, tidy access point in the cockpit and the DSP has room for a straight cable entry. The C2C90 is the 900mm (3 ft) version with a 90° adapter and an included USB-C to USB-A cable — choose it when clearance at the processor is the limiting factor, when the cable must turn immediately at the port, or when the accessible end needs to sit wherever the build puts it. On a deeply buried processor the two are often used together.
The Bottom Line
A 90° USB-C adapter, a 900mm (3 ft) waterproof USB-C extension and a 1.8m (6 ft) USB-C to USB-A cable — the access kit for a Cicada Audio DSP mounted where the port is hard to reach and harder to protect. Add to cart above. For a permanent cockpit access point at the 12V lighter opening, see the C2C; to see the processors these connect to, browse Cicada Audio DSP.

What's in the C2C90
The 90° USB-C adapter is the part that makes a difficult mount workable. It converts a straight-in connection to a right-angle one at the port itself, so the cable leaves the processor parallel to its face rather than perpendicular to it. In a shallow cavity that recovered depth is frequently the margin between a DSP that can be tuned in place and one that has to come off the bike. On the road: the fairing or seat pan closes on a cable that is lying flat, not on one being crushed into a bend.
The 900mm (3 ft) waterproof USB-C male-to-female extension carries the connection point away from the processor to somewhere reachable. Waterproof rating matters here because the route is rarely dry — a fairing cavity collects condensation, a saddlebag space sees road spray, and an under-seat run sits close to whatever the rear wheel throws up. On the road: the connection survives a wet ride and a summer of heat cycling in a sealed cavity instead of corroding quietly until the next tuning session finds it dead.
The 1.8m (6 ft) USB-C to USB-A data cable completes the run to the laptop. Most tuning software still expects USB-A on the computer side, and 1.8m is enough to work with the laptop resting on the pillion seat or a stand beside the bike. On the road: nothing is stretched tight while you are making changes, so an accidental nudge moves the laptop rather than unseating the connection mid-write.
Why a 90° Adapter Matters More Than It Sounds
The USB-C connector standard specifies a durability of around 10,000 insertion cycles, but that figure assumes axial loading — plug in, pull out, straight along the connector's axis. It says nothing about a cable held in a permanent bend, transmitting engine and road vibration into the port shell for months at a time. On a motorcycle that second condition is the normal one. The failure that follows is rarely dramatic: the port develops intermittent contact, then stops enumerating, and the processor has to come out to be re-terminated or replaced.
Turning the cable at the connector removes the bending moment at its root. The 90° adapter takes the strain, the extension holds a fixed shape, and the only part that ever flexes is the short data cable you plug in when you are actually tuning. That is the same logic behind every other strain-relief decision in a bike build — put the wear somewhere replaceable and cheap.
