SPEAKER TOWER INSTALLATION

Unpack and disassemble the clamps from the speaker. Make sure you account for all hardware when removing it from the clamps. There are lock washers that must be re-installed on the clamp.
Determine the location of the speaker.
Determine the correct rubber clamp adapters that are needed for your application.
The rubber adapters will need to be cut to length, so they fit the enclosure and clamp.
After the rubber clamp have been cut, remove the white protective layer and stick them to the clamp and enclosure.
Place the speaker on the tower and have the top clamp ready to place on top.
Screw the two bolts evenly, until snug. Once the position is verified, tighten the bolts another half turn.
DO NOT OVERTIGHTEN.
The speaker accept up to 16 GA wire, it is recommended you use a high-quality marine grade speaker cable for your installation.

BT MODULE INSTALLATION

MOUNTING (BT Module BTRC-R)

To mount the unit, you will need to find a flat surface with adequate clearance behind it that provides enough clearance for the unit and all it’s necessary wiring.

Once you have determined a mounting location, you will need to cut a circular hole 2.87″ (73 mm) in diameter.
After the hole is cut, remove the nut ring unscrewing it from the unit, then slide the unit and wiring through the hole.
Take the nut ring and screw it back on. Tighten down with hand, DO NOT OVER-TIGHTEN.
Plug in all wiring harnesses and cables. Refer to the wiring diagram to make the connections.

AMPLIFIER INSTALLATION

Amplifiers are generally mounted in closed compartments of the vehicle or watercrafts. Select a location that will provide adequate ventilation for the amplifier. Avoid mounting the amplifier in exposed areas.
Secure the amplifier with the screws provided. Before securing the amplifier, inspect the mounting location carefully to ensure that you do not drill into or damage any electrical, hydraulic, fluid, or fuel lines.

Before you start, disconnect the negative cable from the battery, tape up the end so it is isolated from the battery.
Run an appropriate gauge wire from the battery to the amplifier. Plan this part of the installation carefully. this cable will carry very high current. If it should short to the body and it is not properly fused, it could catch fire.
Connect the power wire to the battery using a fuse capable of the total current load of all amplifiers connected. Wait until the end locate the fuse as close as possible to the battery.
Find the closest clear metal area to the amp for a ground. sand, grind or scrape all paint and undercoating from the body and screw the ground securely in place. In some vehicles or boats the ground wire must go directly to the battery, use a proper size and color wire to identify as a ground wire and avoid mixing it with the positive wire.
It is advisable to test the ground with an ohmmeter between the ground cable and the negative battery cable to ensure a good low resistance connection. Some alloys used in modern vehicles do not offer the best ground. If you believe this is the case – first consult with the vehicle manufacturer.
Run the speaker wire to the speakers. It is advised that you leave some extra wire at this point. You can fix it later. This amplifier is a multi-channel amplifier design, meaning it has more than one channel of speaker outputs. It is equipped with a harness over-mold. Connect this carefully and neatly; strip your wire back and twist the exposed leads and use an insulated waterproof marine butt connector. If the wires ever contact each other the amplifier will go into protection mode.
Connect the speaker wires to the amplifier and speakers (make sure the amp is off first). Make sure the polarity (+) and (-) is correct.
Connect the remote wire and the RCA audio signal from the BT Receiver to the amplifier.
If you haven’t done so already, mount the amplifier now.
Only after this step – you should connect back the negative cable at the battery.
Now is a good time to turn on the amp for the first time. This MP.4A amplifier already comes with all the factory settings, it is ready to enjoy with your new speaker system.
