HIGH PERFORMANCE MARINE AUDIO SYN-DX SERIES FULL RANGE CLASS-D AMPLIFIERS SYN-DX 2, SYN-DX 4, SYN-DX 6, OWNER'S MANUAL wetsounds.
1 CONGRATULATIONS! Thank you for purchasing the Wet Sounds SYN-DX series amplifier. Wet Sounds represents the ultimate in High Performance Marine Audio. Wet Sounds SYN-DX Series Marine Amplifiers are designed to be a complete solution for every type of extreme marine application. SYN-DX amplifiers use superior performance circuitry by utilizing Class D Power Supplies. These amplifiers have extreme power output packed inside a small chassis, thermal overload protection, flexible crossovers, extended inputs.
2 INSTALLATION INSTRUCTIONS Wet Sounds Marine Amplifiers are designed for easy installation in your boat. To ensure proper installation of your new purchase please follow all the suggestions listed below. If you do not have experience with marine electrical and mechanical systems contact a professional installer. Paying a qualified installer is almost always cheaper than paying a dealership to repair your boat. LOCATING THE AMPLIFIER The amplifier must be securely mounted to a solid surface.
3 RUNNING THE WIRING CABLES **Always keep the signal cable and the power cables separated to prevent the possibility of inducing noise into the system** Carefully run the power and the signal cables through the boat. Always keep all the wire tight and tied down to prevent the power wire from shorting and reduce the risk of fire. A 4 AWG or larger wire should be used for power and ground connections. We recommend a fuse to be installed on the power wire within 18 inches of the battery for safety.
4 AMPLIFIER SIGNAL INPUTS Connect the RCA outputs from the source unit into the inputs of the amplifier. The SYN-DX Series has 1 pair of inputs for each pair of channels. SYN-DX 2 SYN-DX 4 SYN-DX 6 On the SYN-DX 4, there is 1 input selection switch. The switch is used to designate 2 or 4 channel input. You can select FROM CH 1-2 when only using 1 set of RCA inputs to allow all 4 channels to have output from 1 set of RCAs (CH 1,2,3, & 4). You can select FROM CH 3-4 to use both sets of inputs.
5 SPEAKER TERMINAL INPUTS The SYN-DX Series utilizes removable speaker terminal blocks for easier installations and stronger power connections. The terminal blocks are designed to accept 12 AWG- 16 AWG speaker wire. When preparing the wire you will need to strip 5/8” of the cables protective shielding. Then take a small Phillips or flat head screwdriver and back out the screw on the terminal block. Insert the speaker wire into the terminal block and then tighten the screw back into the terminal block.

Channel 3-4 Input Switch – Adjusting this switch to 2 channel input and connecting only the CH 1/2 inputs allows the amplifier to have 4 channel output. 2. Channel 5-6 Input Switch – Adjusting this switch turns on/off the RCA inputs for channels 5 & 6. 3. Gain Control 1-2 - This is the input sensitivity gain control for channels 1 & 2. 4.
7 AMP DIAGRAM WITH LEGEND 2 1 4 3 5 6 7 8 1. Fuses – The fuses protect the amplifier against internal electrical damage and are meant to protect the amplifier only. All other power connections should be fused at the source 2. (+) 12 Volt Power – Connect this terminal through a FUSE or CIRCUIT BREAKER to the positive terminal of the vehicle battery or the positive terminal of an isolated audio system battery. 3. Remote Turn On – This terminal turns on the amplifier when (+) 12 volt is applied to it.
8 SETTING UP THE AMPLIFIER Input Selection Because of the wide range of head unit/radio output configurations all Wet Sounds amplifiers have an adjustable input sensitivity or “GAIN”. The gain is NOT a volume or a power limiting control similar to a throttle. It makes the amplifier more sensitive to input from the stereo. When the gain is turned up the amplifier will reach full output at lower volume levels on the head unit/radio.
9 TROUBLESHOOTING If you are experiencing problems with your amplifier after installation follow these procedures to try and remedy the problem. 1. Check your fuse and replace if necessary. 2. Confirm your Ground wire has a good connection. 3. Make sure your remote wire and power wire has +12 Volts. 4. Make sure your battery has 12 volts. 5. Confirm that the amplifier LED color is blue. If the light flashing is red than the amplifier is in protection mode.
10 BRIDGED AUDIO RCA CONFIGURATION When connecting two speakers in bridged mode on channels 1-4 on the SYNDX-4, the left and right RCA’s must be split to retain stereo separation. This means you will have left audio out of the CH 1-2 and right audio out of the CH 3-4. You must also switch to FROM CH 3-4 on the input mode section of the control panel on top of the amplifier (example shown below).
