Boss Audio Systems BV7260B Owner`s manual

Important Warnings to Take Note of BEFORE
Commencing Installation
Damage Caused By Incorrect Installation or Usage is
NOT Covered By Warranty.
PLEASE Take the Time to Read the Installation Notes
To Validate the Warranty Please Ensure That the Unit is
Installed by a Professional, VAT registered Car Audio
Installation Company.
To avoid short in your vehicles electrical system, be sure to disconnect
the battery cable before beginning installation.
The unit is intended for vehicles with a 12-volt battery and negative grounding.
Before installing the unit in a recreational vehicle, truck, or bus, check that the
battery voltage is 12 volts.
Remove the two transport screws from the top of the unit before installation.
Be sure to connect the negative (-) speaker leads to the negative (-) speaker
terminal. Never connect the negative (-) speaker leads to chassis ground.
This unit is only designed for use with 4 speakers. Do not combine outputs
for use with 2 speakers. Do not ground negative speaker leads to the chassis
Speakers connected to this unit must be high-power units with a minimum rating of 45W and impedance of 4 to 8 ohms. Connecting speakers with output
and/or impedance values other than those noted there will result in damage
to the head unit and the speakers.
Check the condition off your speakers carefully - connecting the unit to
old of degraded speakers may result in a fault which will damage the
audio IC and invalidate the warranty.
If this unit is installed in a vehicle that does not have an ACC (accessory)
position on the ignition switch, the red lead of the unit should be connected to
a terminal coupled with ignition switch ON/OFF operations. If this is not done,
the vehicle battery may be drained when you are away from the vehicle for
several hours.
Secure the wiring with cable clamps or adhesive tape. To protect the wiring,
wrap adhesive tape around them where they lie against metal parts. To avoid
short-circuiting, cover all disconnected lead with insulating tape. There is a
possibility of short-circuiting if the leads are not insulated.
Route and secure all wiring so it cannot touch any moving parts, such as the
gear lever and handbrake. Do not route wiring in places that get hot, such as
near the heater outlet. If the insulation of the wiring melts or gets torn, there is
a danger of the wiring short circuiting to the vehicle’s body.
Don’t pass the yellow lead through a hole into the engine compartment to
connect to the battery. This will damage the lead’s insulation and cause a very
dangerous short.
Do not shorten any leads, if you do, the protection circuit may fail to work
when it should.
Never feed power to other equipment by cutting the insulation of the power
supply lead of the unit and tapping into the lead. The current capacity of the
lead will be exceeded, causing overheating.
Since a unique audio I/C circuit is employed, never wire so the speaker leads
are directly grounded or the left and right - speaker leads are common.
When this product’s source is switched ON, a control signal is outputted
through the orange lead. Connect to an external power amp’s system remote
control or the car’s Auto-antenna relay control terminal (max. 300mA 12V DC).
If the car features a glass antenna, connect to the antenna booster power
supply terminal.
When an external power amp is being used with this system, do not connect
the orange lead to the amp’s power terminal. Such connection could cause
excessive current drain and a major malfunction. Refer to the relevant owner’s
manual for details on connecting the power amp and other units, then make
the connections correctly.
Do not block any vents or heater panels, Blocking them will cause heat to build
up and may result in fire.
If noise is still experienced when the motor of the vehicle accelerates, a choke
should be placed in line with the power to the unit. The installation company
will know what is required.
When replacing the fuse(s) the replacement must be of the same amperage
as shown on the fuse holder. Never replace a fuse with another of a different
value. If the fuse blows again please contact your instsallation company.
Double check that all wiring and connections are correct before re-connecting
the battery and turning on the unit.
After completing the installation and before operating the unit, reconnect the
battery, then press the (RES) button with a pointed object, such as a ball-point
pen to set to unit to it’s initial status. After pushing the button, wait a few seconds for the red light to flash.
Tools for Installation
2 removal wrenches are supplied for taking out the old unit and place with this
brand name car radio. The following tools and supplies may also be needed for
the installation:
Tools for Installation: Philips Screw-drivers /Machine Screws /Wire Stripper
/Wire Cutter /Hammer /Pencil /Electrical Tape /Electric Drill
Supplies for Installation: Machine Screws /Crimp Connectors /14 Gauge Wire for

Before you install
Automotive audio equipment installations can be challenging even to the most
experienced of installation technicians. We strongly recommend that this unit
should be professionally installed by a VAT registered installer (this is a requirement to validate the warranty).
IMPORTANT: Remove the two transport screws from the top fo the unit before
Remove the Old Unit from the Dashboard
1. Remove the outer trim frame.
DIN Front Mount
2. Insert the keys supplied with the
old unit into both sides of the unit
as shown in figure below until
they click. Pull to remove the old
unit from the dashboard.
Mark Polarity of the Speaker Wires
Marking the polarity of the speaker wirers will make it easier to connect the
existing speakers to your car radio. Consult wiring diagram of existing head unit
before disconnecting any wires. If you are not positive of the polarity of the existing wires from the speakers to the head unit, install new wires.
1. While the old unit is playing, disconnect the wires from one speaker.
2. Take a length of masking tape and fold it around the wire so it forms a flag.
3. On the masking tape mark the polarity of the speaker wires (+&-), as well as
left or right, and front or rear.
4. Double check that you marked the first speaker correctly by checking that the
speaker wires are the same at the head unit.
5. Repeat this procedure for all of the speakers.
6. Mark the power, ground, and any other wires also.
Disconnect negative battery terminal from battery before starting installation. Consult the vehicle’s owner’s manual for proper
NOTE: Mark the polarity of the existing speaker wires before disconnecting battery.
NOTE: Remove the two transport screws from the top of the unit
before installing.
DIN Front Mount
1. After removing the old radio
and mounting sleeve, insert supplied mounting sleeve into opening.
3. Attach wires from the unit to
existing wires. See wiring connections diagram. Insert radio
into dashboard. Then apply the
trim frame to outside of radio.
2. Bend the tabs on the mounting sleeve to keep the mounting sleeve firmly in place.
4. Support radio using rear mounting
bolt and steel bar. (not included)
DIN Rear Mount
NOTE: Outer trim frame, hook, and mounting sleeve are not used
for this installation
This is only intended as a general guide; contact the vehicle’s manufacturer for
specific instructions.
This menthod of installation uses the screw holes at the sides of the unit and
the holes of the existing vehicle mounting bracket.
1. Remove the hooks on both sides.
2. Aligh the screw holes of the mounting bracket supplied with the car and the
screw holes of the main unit. Tighten the 2 screws on each side of the unit.
Then fasten the brackets to the car.
3. Attach wires of the unit to existing speaker wires. See wiring diagram.
Make sure You have a good chassis ground. Good ground connection will
eliminate most electrical noise problems. A good chassis ground requires a
tight connection to the vehicle’s metal chassis. The area around the ground
connection should be clean, bare metal without rust, paint, plastic, dust, or dirt
for a good ground connection.
Black Ground
Connect to vehicle body/chassis. Make sure you have a good chassis ground.
This will eliminate most electrical noise form the motor and alternator. A good
chassis ground requires a tight connection to ground. The area should be free
from rust, paint or any form of dirt.
