Product Research
Features
Overview: The Cicada CX600.4D is a 4-channel full-range Class D amplifier. The amp is bridgeable, so it can also be wired as 3-channel or 2-channel.
RMS Power Output:
- 92W x 4 @ 4-ohms (14.4 volts)
- 115W x 4 @ 2-ohms (12.5 volts)
- 152W x 4 @ 2-ohms (14.4 volts)
- Bridged: 218W x 2 @ 4-ohms (12.5 volts)
- Bridged: 302W x 2 @ 4-ohms (14.4 volts)
Gain: Two rotary gain controls (Ch.1/2 & 3/4) let you run low-level or high-level audio signals ranging from 200mV up to 12V into each set of RCA inputs (adapter required for high-level signals).
Crossover: Two crossovers are provided (Ch. 1/2 & 3/4) with the following options:
- Crossover Selector: A 3-position crossover switch lets you choose LPF, Full, or HPF. The low-pass and high-pass crossovers both have a 12 dB per octave slope.
- Frequency: The crossover point is set with a rotary dial; it is continuously variable from 40-400 Hz.
Auto Turn-on Switch: A 3-way switch determines the turn-on method for the amplifier; DC Offset and VOX can be used with speaker-level input signals, while the REM method must be used if running low-level input signals:
- DC Offset: Senses the DC offset on the high-level input signals to activate the amp.
- VOX: Uses signal sensing on high-level input signals to activate the amp.
- REM: Uses a +12V trigger on the Remote terminal to activate the amp when using low-level input signals.
2CH/4CH: A 2-way switch determines whether all four channels will be fed by individual input signals or from only the Front input channels.
Power/Protect LED: A single LED will illuminate Green when the amp is powered on and will change to Red if the amplifier goes into protect mode.
Power Terminals: The power, ground, and remote terminals are provided on a removable terminal block; power and ground terminals will accommodate up to 4-gauge wire (8-gauge is recommended), while the remote turn-on terminal can accept wire up to 8-gauge (18-gauge is usually sufficient). The set screws are tightened/loosened with the included 2mm and 3mm hex keys.
Fuses: The amplifier does not have on-board fuses. A 40-amp fuse should be placed on the power wire within 18" of the battery.
Speaker Outputs: The 4-channel speaker outputs are provided on two 8" harnesses with bare-ended 18-gauge wire.
RCA Inputs: The four input channels are provided on two 9" harness terminated in RCA jacks. If running speaker-level inputs, RCA to speaker wire adapters must be used and are sold separately (see Accessories list).
Mounting: The amplifier can be mounted vertically, horizontally, or inverted using the supplied 3M hook-and-loop fastener or the supplied mounting screws.

Fantastic little amp! Popular on Harleys but perfect for a boat for all the same reasons. Small, waterproof and powerful. Very solid product!
