If you are not sure of your ability to install the amplifier, entrust this task to a Focal dealer in order to take full advantage of everything your FPX amplifier can do. Cabling your FPX amplifier Only use the connection points specified in the user manual and the accessories supplied. The speaker cable must ONLY be used to connect the amplifier to the speakers. The gauge of the power cables must match that shown in the table (paragraph 3.1). This gauge depends on the power of the amplifier and the cable length required. Use double or triple shielded RCA cables to prevent any interference to the low level signal. Operating time for your FPX amplifier Avoid using the amplifier for extended periods without starting the vehicle. This can lead to flattening the battery. Ventilation It is essential to leave the upper part of your FPX amplifier uncovered to prevent overheating. Items required for installation (in addition to accessories provided) • 2 appropriately sized cable sheaths (1 for the power cable and one for the set comprising speaker cables, remote, RCA modulation) • Multimeter (volts/amps) • Soldering iron and solder • Crimping tool • Wire stripper • Wire cutter • Battery terminal spanner • Hand drill and drill bits • Heat shrink sleeving in appropriate diameters for the different cables • Power cable of appropriate length and gauge • Remote switch-on wire of appropriate length and gauge (REM input on amplifier) • Ground (earth) wire of appropriate length and gauge • Fuse holder and suitable fuse • Connector to positive (+) battery terminal • Connector to vehicle chassis (-) • Bolt with 6 mm head (minimum) with appropriate nut for grounding (earthing) to vehicle chassis Installation This section covers points relating to the vehicle that must be taken into account for the installation of your amplifier. You will save time by planning the positioning of your system and its cabling in advance. During this preparatory phase, ensure that all adjusters remain accessible once installation is complete. FPX Premium amplifier User manual 6 Before commencing installation please scrupulously follow the following instructions: 1 - Read the instructions in full and be sure that you fully understand them before installing your amplifier. 2 - Disconnect the cable from the negative terminal on the vehicle battery before beginning installation (Fig. 1). 3 - For ease of fitting we suggest you put all wires in position before installing your amplifier. 4 - Route the RCA, speaker and REM cables away from power cables to avoid any signal interference. 5 - Use good quality connectors/fittings or good quality soldered joints when connecting the amplifier to ensure a secure installation and to minimise signal or power losses. 6 - Before carrying out any operation ensure you are not cutting or drilling the fuel tank, any fuel, brake, hydraulic or vacuum line or any electrical wiring or safety-related item. 7 - Never run any wiring under the vehicle. It is essential to run wiring inside the vehicle. When running cables, ensure they do not interfere with operation of the vehicle. Cabling that obstructs or passes over such items as the steering wheel, the pedals (brake, accelerator and clutch, etc.) could be extremely dangerous. 8 - Avoid running wires over or through sharp edges. All wiring routed through metal must be protected by a grommet. Route wiring away from moving parts (e.g. seat rails) and sharp or pointed edges. This will also protect cables from being pinched or damaged with the consequent risk of an electrical short-circuit. 9 - Always use fuses to protect the battery and the electrical circuit from any potential damage. Install a fuse-holder and an appropriate fuse in the 12V+ power supply cable less than 40cm from the battery terminal. Ideally, this distance should be as short as possible (Fig. 7). 10 - Prepare the chassis ground (earth) by removing all traces of paint from the metal surface, thus ensuring a good ground (earth) contact. Ground (earth) connections should be as short as possible and ALWAYS connected to metal welded to the vehicle bodywork or chassis (Fig. 2). The grounding (earthing) point usually chosen is the one used to connect the negative terminal of the battery to the vehicle chassis. 11 - NEVER install this product in a vehicle's engine compartment. To do so would void the warranty. 1 - Positioning your FPX amplifier Choosing a correct location for your FPX amplifier Because of the amplifier's power, it needs heat dissipation for its operation. For this reason the amplifier must be mounted in a ventilated location, especially above it. Avoid fitting it into any location that is close-fitting or covers the amplifier in its immediate vicinity. 2 - Securing your FPX amplifier in place Position your amplifier in the desired location and mark it. Mark the attachment points in its support. Use the mounting screws supplied (screws supplied are suitable for screwing into a wood base). 3 - Cabling your FPX amplifier CAUTION If you have any doubt over your ability to correctly install the amplifier and wiring, entrust this task to a Focal dealer/ installer. FPX Premium amplifier User manual 7 3 - Cabling your FPX amplifier WARNING Do not run the power cables near the low level inputs, high level inputs, antenna or sensitive equipment or cabling. The power cables carry a high current, capable of interfering with the audio signal. WARNING Use the shortest possible cable lengths to optimise the quality of the installation and limit signal losses. WARNING Before beginning the connection phase, remove the negative (-) terminal from the battery of the vehicle (fig.1). 3.1 Choosing cable of the correct gauge Your FPX amplifier requires a power supply of the correct amperage. The cable gauge to be used depends on the distance of the cable from the battery, as recommended in the following table: Amplifier Amperage Length of cable (meters) 0-2 m 2-4 m 4-6 m FPX 4.800 and FPX 2.750 60 A 16mm2 / 5 AWG 21mm2 / 4 AWG 35mm2 / 2 AWG FPX 1.1000 90 A 21mm2 / 4 AWG 35mm2 / 2 AWG 53mm2 / 0 AWG FPX 4.400 SQ 50 A 8mm / 8 AWG 16mm / 5 AWG 21mm2 / 4 AWG 2 2 It is essential to scrupulously adhere to the recommendations in this table for the safety of your electrical system; it is also important to maintain the maximum performance of your FPX amplifier. 3.2 - Cabling your FPX amplifier's input signals Route all the modulation cables (RCA), speaker cables, and the REM cable together, isolating them from other highpower consumption equipment in the vehicle and, in particular, electrical motors (e.g. windscreen wiper motor, etc.) Do not cut any cables down yet. You will do this later. 3.3 – Wiring your FPX amplifier's power supply 3.3.1 – Route the positive (+) power cable, taking care to keep it away from the cables you have already positioned, to avoid any interference. DO NOT CONNECT THE CABLE YET. FPX Premium amplifier User manual 8 3.3.2 – Locate the negative (-) power cable. This cable should be as short as possible and ideally should not exceed 1 meter in length, in order to ensure an optimal connection between the amplifier and the vehicle chassis. The cable and its gauge must be in accordance with the table in 3.1. Locate an appropriate ground (earth) point, then sand it to remove all traces of paint or other finish, thus optimising the quality of the connection. Drill through the sheet metal you have previously sanded, making a hole to match the bolt you have chosen, ensuring you are well clear of all cable routes, reservoirs or tanks or other sensitive vehicle parts. Solder and insulate (using heat shrink sleeving) the earth cable to the FPX amplifier earth connector supplied (Fig. 2). fig. 2 3.4 - Connecting input connectors to your FPX amplifier You may now begin the input/output cable connection phase. Connect the RCA connectors (Fig. 3), paying attention to polarity and distribution. Connect the other end to the amplifier's INPUTS connection panel. fig. 3 FPX Premium amplifier User manual 9 3.5 - Connecting the speakers and the remote to your FPX amplifier Solder and insulate (using heat shrink sleeving) the REMOTE cable to the cable connector provided (Fig. 4). Connect the other end of the REMOTE cable to the REMOTE terminal on the head unit. fig. 4 Finally, connect the speaker cables to the amplifier, taking care to match polarities (+ to +, - to -). (Fig. 5). fig. 5 WARNING All speakers or speaker sets cabled to your FPX 4.800, FPX 4.400 SQ or FPX 2.750 amplifier must always have an impedance greater than 2 ohms. WARNING All speakers or speaker sets cabled to your FPX 1.1000 amplifier must always have an impedance greater than 1 ohm. FPX Premium amplifier User manual 10 WARNING In bridged mode, all speakers or speaker sets connected to your FPX 4.800, FPX 2.750 or FPX 4.400 SQ must always have an impedance greater than 4 ohms. Any use of lower impedances would result in the voiding of the warranty. To use a FPX amplifier in bridged mode and thus double the power available, observe the connections and polarities shown below in: "BRIDGE" (Fig. 6). FPX 4.800 fig. 6 FPX 2.750 fig. 6 FPX 4.400 fig. 6 FPX Premium amplifier User manual 11 3.6 – Power supply wiring WARNING The cable connecting the positive (+) battery terminal to the "+BATT" terminal on the amplifier must ALWAYS have a fuse suitable for the power of your amplifier, positioned 40 cm or closer to your vehicle battery. Fuse holder connections must be sealed. Disassemble the fuse holder, taking care to remove the fuse. Secure the base of the fuse holder. Cut a length of power cable between 10 and 40 cm (max.). Strip 1 cm and tin. Screw the cable into the terminal on the battery side of the fuse holder. Crimp the power cable into an appropriate connector and screw this to a source of battery power. Strip 1 cm at the end of the remaining length of cable and tin. Screw the cable into the other terminal of the fuse holder. fig.7 Solder and insulate (using heat shrink sleeving) the positive (+) power cable to the FPX amplifier connector supplied (Fig. 7). 3.7 – Start-up and checking The connection phase is now complete. It now remains to check the power supply is good and the correct operation of the system (head unit/amplifier/speakers). Set the source gain to minimum. Set the gain on your amplifier at 1/3 of its total travel. Power up all the components. Once all components are switched on, test at low volume. 4 - Control panel and connections FPX 4.800 fig.8 FPX Premium amplifier User manual FPX 2.750 FPX 4.400 SQ FPX 1.1000 12 FPX Premium amplifier User manual 13 INPUT: These connectors are for low level signal inputs. OUTPUT: These connectors (FPX 1.1000 and FPX 2.750) allow mirroring. REMOTE: This connector (FPX 1.1000 and FPX 2.750) is for connecting the accessory volume control. GAIN: The rotary GAIN control is for adjusting the level of the signal entering the amplifier. Voltage gain varies from 0.2 to 5V. Optimisation of the performance of the audio system consists of applying the maximum gain upstream in the system and the lowest gain downstream. This control should be adjusted to suit the level of the sound source (line output level). Start by setting the amplifier gain at its lowest level. Gradually increase the level (volume) of the source up to 3/4. Increase the gain on the amplifier up to the maximum desired listening level. Reduce the level if distortion occurs. MODE: This switch (FPX 4.800 and FPX 4.400 SQ) allows channels 3 and 4 to mirror, if required, the signals from channels 1 and 2. Thus, if you only have one stereo output (a right and a left), you can still amplify all four channels by activating 2CH mode. If you wish to use FPX in its four independent channel mode, select 4CH. PHASE (°): The rotary PHASE control is used to adjust channel phasing with the rest of the system. A readjustment of the phase of the subwoofer makes it possible for the subwoofer and the rest of the speakers to play simultaneously at the crossover frequency. For a theoretical signal period, one of the sources is slightly shifted so that at the listening position the phasing is perfect. X-OVER MODE: This switch enables users to choose between a high-pass filter (HPF), a low-pass filter (LPF) or non filtered mode (FULL). X-OVER FREQ (Hz): Adjustment of the cross-over filter frequency. This rotary control adjusts the setting of the lowpass or high-pass filter. The value selected defines the frequency up to which or from which the signal will be cut. F-MULT: This switch activates a 10X multiplier for the setting value of the cut-off frequency. SUBSONIC: This rotary control is used to remove sub-bass frequencies below a selected frequency. BASS BOOST: This rotary control is used to raise the bass sound level from 0 to 12 dB.

GND: The GND (ground) connector is designed to accept the negative (-) power cable that connects the amplifier to the vehicle chassis. REM: The REM connector is for the connection between the amplifier and the source (head unit) via a REM or REMOTE output on the head unit. This switches the amplifier on automatically when the source (head unit) is switched on. POWER and PROTECT: These indicator lights are for checking that the amplifier is working correctly. The POWER light, continuously lit, indicates that the unit is working correctly. The PROTECT light, continuously or intermittently lit, indicates that the product is working abnormally. Refer to troubleshooting in 5. FUSES: The FUSES connector is for holding the amplifier fuses. Ensure that any replacement fuses perfectly match the amperage of the originals. 5 - Troubleshooting The statuses of the various LEDs are used to indicate certain failure modes or causes of breakdowns.
