INSTALLATION (Fig. 1)
Due to the high power output of the MRV-M250, considerable heat is produced when the amplifier is in
operation. For this reason, the amplifier should be mounted
in a location which will allow for free circulation of
air, such as inside the trunk. For alternate installation locations, please contact your authorized Alpine dealer.
1. Using the amplifier as a templat e, mark the four screw locations.
2. Make sure there are no objects behind the surface that may become damaged during drilling.
3. Drill the screw holes.
4. Position the MRV-M250 over the screw holes, and secure with four self-tapping screws.
NOTE:
•
To securely connect the ground lead, use an already installed screw on a metal part of the vehicle (marked
(*))or a clean, ba re metal spot on the vehicle's chassis. Be sure this is a good ground by checking continuity
to the battery
(-) terminal. Connect a ll equipment to the same ground point while keeping wire length as
short as possible. These procedures will help eliminate noise.

CONNECTIONS (Fig. 2 - Fig. 3)
Before making connections, be sure to turn the power off to all
audio components. Connect the battery lead from the
amp directly
to the positive (
+) terminal of the vehicle's battery with appropriate
in-line vehicle's fuse (see Battery Lead section). Do not connect
this lead to the vehicle's fuse block.
To prevent external noise from entering the audio system.
• Locate the unit and route the leads at least 10 em (3-15/16")
away from the
car harness.
• Keep the battery power leads as far away from other leads as
possible.
• Connect the ground lead securely to a bare metal spot
(remove any paint
or grease if necessary) of the car chassis.
• If you add an optional noise suppressor, connect it as far away
from the unit as possible. Your Alpine dealer carries various
noise suppressors, contact them for further information.
• Your Alpine dealer knows best about noise prevention
measures so consult your dealer for further information.
0 Speaker OutputTerminals
The MRV-M250 has one set of speaker outputs. Be sure to
observe correct speaker output connections and polarity
in
relation to the other speakers in the system. Connect the positive
output to the positive speaker terminal and the negative to
negative. Do not connect the
speaker(-) terminal to the vehicle's
chassis.
NOTES:
• Do not connect speaker leads together or to chassis ground.
• The input is stereo but the output is monaural.
• Reversing subwoofer polarity may be desirable
in some
installations for optimum bass performance.
8 Fuse: 30A
• USE THE CORRECT AMPERE RATING WHEN REPLACING
FUSES.
Failure to
do so may result in fire or electric shock.
f) Power SupplyTerminal
0 Battery Lead (Sold Separately)
Be sure to add an in-line fuse with the battery lead as close as ...
possible to the battery's positive (+) terminal. This fuse will protect
your vehicle's electrical system in case of a short circuit. Consult
the table below for appropriate fuse value and minimum wire
gauge requirement.
• 30

0 Remote Turn-On Lead (Sold Separately)
Connect this lead to the remote turn-on (positive trigger, (+)
12V only) lead of your head unit. If a remote turn-on lead is
not available, see "Connection Checklist (Fig. 5)" section for
alternative method.
NOTE:
• If using speaker input level signal from the head unit, remote
turn-on lead connection is not necessary due to automatic
signal detection.
0 Ground Lead (Sold Separately)
Connect this lead securely to a clean, bare metal spot on the
vehicle's chassis. Verify this point to be a true ground by checking
for continuity between that point and the
negative(-) terminal of
the vehicle's battery. Ground all your audio components to the
same point on the chassis to prevent ground loops while keeping
wire length as short as possible.
Minimum required wire gauge for this connection is as follows:
• 8AWG/8mm2
8 Speaker Level Input Connector
These input leads are for use with head units not equipped with
preamp outputs.
When not using the RCA Line Input connectors,
you should connect these wires to the speaker output leads of
your head unit. The MRV-M250 accepts input from high power or
standard power head units.
NOTES:
• Use either RCA line level or speaker level inputs. Do not
connect both at the same time.
• For the "Speaker Level Input System" setting, connecting the
Remote Turn-On Lead is not required
due to the "REMOTE
SENSING" function of this product. However, the "REMOTE
SENSING" function may not
work depending on the signal
source connected.
In such a case, connect the Remote Turn-On
Lead to an incoming power supply cord (accessory power)
in
the ACC position.
Ci) Speaker Input Leads
These leads are input leads for use with head units not equipped
with preamp outputs. When not using the

CONNECTION CHECKLIST (Fig.5)
Please check your head unit for the conditions listed below:
(Fig. 5)
a. The head unit does not have a remote turn-on or power
antenna lead.
b. The head unifs power antenna lead is activated only when
the radio is on (turns off
in the tape or CD Mode).
c. The head unifs power antenna lead is logic level output(+)
5V, negative trigger (grounding type), or cannot sustain (+)
12V when connected to other equipment
in addition to the
vehicle's power antenna.
If any of the above conditions exist, the remote turn-on lead
of your MRV-M250 must be connected to a switched power
source (ignition)
in the vehicle. Be sure to use a 3A fuse as
close as possible to this ignition tap. Using this connection
method, the MRV-M250 will turn on and stay
on as long as
the ignition switch is on.
If this is objectionable, a SPST (Single Pole, Single Throw) switch,
in addition to the 3A fuse mentioned above, may be installed in-
line on the MRV-M250 turn-on lead. This switch will then be used
to turn on (and off) the MRV-M250. Therefore, the switch should
be mounted so that is accessible by the driver. Make sure the
switch is turned off when the vehicle is not running. Otherwise, the
amplifier will remain on and drain the battery.
