WARNING

Do not operate any function that takes your attention away from driving your vehicle safely.
Any function that requires your prolonged attention should only be performed after coming to a complete stop.
Always stop the vehicle in a safe location before performing these functions. Failure to do so may result in an accident
Keep the volume at a level where you can still hear outside noises while driving.
excessive volume levels that obscure sounds such as emergency vehicle sirens or road arning signals (train crossing, etc) can be dengerous and may result in an accident. Listening at loud volume levels in a car may also cause hearing damage.
Do not disassemble or alter. Doing so may result in a accident, fire or electrilc shock.
Use this product for mobile 12V applications.
Use the correct ampere rating when repolacing fuses. Failure to do so may resultin a fire or electrilc shock.
Do not block vents or radiator panels. Doing so may cause heat to build up insideand may result in fire.
Make the correct connections. Failure to make the propper connection may result in fire and/or product damage.
Use only in vehicles with a 12V Negative Ground. Failure to do so may result in fire and/or product damage. (Check with your dealer if you are not sure)
Before wiring, disconnect the cable from the negative battery terminal.
Do not allow cables to become entangled in surrounding objects. Arrange wiring cables in compliance with the manual to prevent obstructions when driving. Cables or wiring that obstruct or hang up on places such as the steering wheel.
Do not splice into electrical cables. Never cut away cable insulation to supply power to other equipment. Doing so will exceed the current carrying capacity of the wire and result in fire or elictrical shock.
Do not damage pipe or wiring when drilling holes. When drilling holes in the chassis for installation, take precautions so as not to contact, damage or obstruct pipes, fuel lines, tanks or electrical wiring. Failure to take such precautions may result in fire.
Do not use bolts or nuts in the brake or the steering system o make ground connections.
Keep small objects such as bolts or screws out of the reach of children. Swalloing them may result in serious injury. If swallowed, consult a physician immediately.

Caution on connection terminal/parts. Keep electrically conductive objects away from the units terminals/parts (power terminals, fuses,speaker input terminals, RCA connectors, etc) Doing so prevents a possible short circuit and damage to the unit.
Mounting: Attach the including mounting brackets to the SQBASSX2 with the supplied screws. (at Fig. 1) Once the brackets are mounted to the SQBASSX2 place the subwoofer in the desired location within the vehicle. Before securing with screws, check to make sure all screws can affix to a structurally solid surface while avoiding vehicle wiring, components, etc. (at Fig. 2)
NOTE:
For securing the mounting brackets to the vehicle, it may be necessary to use longer screws (not included) to securely connect the ground lead, use an already installed screw on the metal part of the vehicle. (mark this as a good ground by checking continuity to the battery(-) terminal. To avoide and reduce as much noise as posible, please connect all equipment to the same ground point.

CONNECTION

MAKING CONNECTIONS:

• Turn every audio component OFF
• Connect the red battery lead from the amp to the positive (+) terminal of the vehicle’s battery
• Locate the unit and rout the leads at least 10 cm (3-15/16”) away from the vehicle’s harness
• Keep the battery power leads as far away from other leads as possible
• Connect the ground lead securely to a bare metal spot from the vehicle’s chasis (remove any paint or grease if necessary)
  NOTE: Head unit and RCA extension cables are sold separately
