Mounting
A Focal power is available to your dealer store.
• Unplug the "+" from the battery.
• Make sure you follow the car manufacturer instructions (airbag, alarm system, computer, immobiliser ...).
• Always use battery lead connections.
Cable routing
The 12V supply cables should be passed down one side of the vehicle and the signal cables down the other. These
cables must be suitably protected to avoid any damage to the insulation, especially when feeding the cable through
from the engine compartment to the passenger cabin.
Installation
We have taken time to design a product that will work exceptionally well. To add to this we have included a fixing kit to
ensure the subwoofer remains securely mounted. Please follow the below mentioned steps to ensure the subwoofer
is mounted correctly.
• Rear seats must be positioned in their normal fixed position.
• Decide the best location possible that suits your automobile and space available. We recommend the best location
for optimum sound quality and most secure is to position behind the rear seats, in the trunk of the automobile.
Power supply ’
(+) The 12V cable (BAT) must be connected to the battery with a cable of appropriate quality and size, 8mm
(7AWG).
2
Protect the installation with a 15A fuse on this cable fitted less than 40cm (16") away from the battery.
(-) The ground wire (GND) must be connected to the chassis of your vehicle with a perfect electrical connection
(remove some paint to reveal bare metal if necessary) and with a cable of the same specification as used for the +
feed.
Connect the remote cable (REM) to the electrical aerial output or to the remote output of your radio.
Low-level input (RCA) Œ
Connect to the RCA output of the radio.
High-level input
Connect to the speaker outputs of the head unit.
Never connect the RCA and the high-level inputs together.
Adjusting the gain Ž
The volume setting allows you to match the level of the Bomba BP20 with the level of the front system.
Setting:
• Turn the gain on the Bomba BP20 down completely.
• Turn the radio up to a normal listening level.
• Turn the gain Ž up on the Bomba BP20 until you get the required balance.
Phase inverter
It allows you to phase the subwoofer (generally advised) or unphase it.
The right setting is determined by listening and finding the one (matching with the front system) that provides the
most bass.
