Installation Instructions (Reference Diagrams on Page 7 to 11)
1. Disconnect the negative cable from the boat battery. Tape up the end so it is isolated from the
battery.
2. Run a red 4 AWG wire from the battery to the amplier. Plan this part of the installation carefully.
This cable will carry a very high current (or battery switch common post). If it should short to any
metal and is not properly fused it could catch re.
3. Connect an in-line fuse holder to the power cable no further than 12” away from the positive
battery terminal. If one amplier is being used, refer to the table below for recommended fuse
rating. If two or more ampliers are being used, verify the fuse and wire are capable of handling the
total current load of all ampliers connected. To protect each amplier, use an in-line fuse holder or
fused distribution block within 18” of the ampliers, again referring to the table below. Do not install
the fuse(s) until the end of the installation.
Please refer to the following recommended fuse ratings for your specic amplier:
• 600.1 Amplier - 50 Amp Fuse
• 500.2 Amplier - 40 Amp Fuse
• 600.4 Amplier - 50 Amp Fuse
• 800.5 Amplier - 80 Amp Fuse
4. Run the black 4 AWG ground wire directly to the negative (-12V) pole on the battery. This wire
should handle the load in the previous step and be as short as possible.
5. Wire your speakers and route wires to your amp mounting location.
6. Connect the power and the ground wires to the amplier.
7. Connect the blue remote wire from the head unit to the “REMOTE” connection of the amplier.
** Only after this step should you install the fuse at the battery**
8. Turn on the amplier to verify it is wired correctly and does not go into protection mode. The
power LED should turn solid green after a few seconds.
9. Once you verify you have a steady green light please turn the amplier off to complete the
remaining connections.
10. Connect the speaker wires to the amplier, making sure the polarity (+ and -) are correct.
11. Connect the RCAs to the appropriate inputs on the amplier.
You must now set the controls on the amplier.
This is the most important part of an ampliers installation and should be
completed by a trained audio professional.
