SOLID AMpLIfIer

1) Amplifier fixing
The SOLID 2 amplifiers can be fixed with the 4 supplied screws and the SOLID 1 and 4 with the 5 screws. It is recommended to insert a
MDF sheet between the fixing surface of the vehicle and the amplifier (fig. B).
2) Installation :
Unplug the negative power supply terminal of the battery before starting the installation (fig. A).
2.1) Remove the protection cap of the amplifier with the help of the supplied Allen key (fig. C).
2.2) Connect the positive power supply terminal of the amplifier to the battery
Please refer to the table below to know the suitable power supply wire gauge. Connect the positive power supply wire to the amplifier
("+BATT"), then convey this wire towards the battery. Install a fuse-box integrating a fuse with the same value as the one in the amplifier
at 40cm maximum of the battery positive terminal (fig.D). Connect the fuse-box to the battery positive terminal. The SOLID amplifiers are
supplied with the Auto Power function. This function replaces the traditional "remote" terminal and provides an automatic switch-on of the
amplifier as soon as it gets a high-level signal (starting the head unit).

2.3) Connect the amplifier ground to the vehicle chassis
Use a power supply wire with the same gauge as the one linking the positive power supply terminal of the amplifier and the one of the
battery. Always connect the ground on a metallic part perfectly scrubbed of any paint or varnish trace. Then connect the other extremity of
the ground wire to the "Power GND" ground terminal of the amplifier.
2.4) Connect the source to the amplifier
Connect, up to your choice, the low-level (INPUT) or high-level (HI-LEVEL INPUT) wires.
Low-level wiring (INPUT): This connection mode offers a higher quality compared to the high-level wiring. You should then favor the low-
level wiring if you have this possibility. Connect the RCA wire to the "INPUT Left" and "INPUT Right" terminals of the amplifier. Convey the
wire to the source and connect it to it on the RCA terminals respecting polarities (fig. E).
High-level wiring (HI LEVEL INPUT): This connection mode permits to convey the signal between the head unit and the amplifier in the case
that the head unit has no low-level outputs (RCA). Use the supplied high-level connector and weld each wire to the corresponding speaker
wire respecting polarities (fig. G). Link the head unit speaker outputs to the connector wires and plug in the connector to the amplifier.
NOTE : The SOLID 4 amplifier is supplied with two high-level connectors in order to link together the whole head unit speaker outputs with
the amplifier inputs (see fig. H for the wiring polarities).
NOTE : The SOLID 1 amplifier is provided with a low-level output (LINE OUTPUT). This output permits to convey the low-level signal towards
another amplifier. This output is not filtered and thus retranscribes the transmitted low-level signal by the head unit without any change.
2.5) Connect the REMOTE CONTROL (only supplied with Solid 1 and Solid 4 amplifiers). Connect the remote control wire with the REMOTE
CONTROL input of the amplifier, then connect it to the remote control. This control must be placed next to the driver, easy to access and it
permits the gain control of the amplifier (channels 3 and 4 of the SOLID 4 amplifier and channel 1 of the SOLID 1 amplifier).
2.6) Connect the speakers to the amplifier
The SOLID 2 and SOLID 4 amplifiers are compatible with an impedance load between 2 and 4 Ohms. The SOLID 1 amplifier can take an
impedance load between 1 and 4 Ohms.
Use a wire with 1.5mm2 minimum gauge. Connect the speaker(s) to the SPEAKER terminals of the amplifier respecting polarities
(fig. I to R).
