Installation/Wiring

1.) Determine installation location

Black-and-white line diagram labeled "1" in a black circle in the top-left corner. The illustration depicts the interior structural frame of a boat cabin. A prominent black arrow points from the top left down toward a small vertical oval outline drawn with dashed lines on an interior wall section just below the cabin windows.

2.) Mount the cutting template at the installation location

Step 2 illustration showing a Rockville RKL80M speaker cutout template. The template indicates an 8-inch (203 mm) outer diameter, a 7.50-inch (190.5 mm) cutout diameter, and four 4.2 mm mounting holes. A hand holds the template in place while another hand marks or cuts the circular opening.

3.) Use the drill to make the mounting holes, being careful to not rip the template.

Step 3 instruction diagram for the Rockville RKL80M speaker installation. A square mounting template is taped to a mounting surface at all four corners. One hand holds the template flat, while the other hand holds a cordless power drill, drilling a pilot hole into the top edge of the dashed circular cut line. Dimensions listed on the template include an outer diameter of 8 inches (203 mm), an inner diameter of 6.89 inches (175 mm), a 7.50-inch (190.5 mm) mounting diameter, and four small drill points labeled 4-ø4.2.

4.) Use a utility knife or any other appropriate tool to cut out the mounting hole.

Step 4 instruction diagram for the Rockville RKL80M speaker installation. A square template with the Rockville logo is taped to a mounting surface at all four corners. One hand holds the template flat, while the other hand uses a utility knife to trace and cut along the dashed circle marked "CUT LINE." The template lists dimensions including an outer diameter of 8 inches (203 mm), an inner diameter of 6.89 inches (175 mm), a 7.50-inch (190.5 mm) mounting diameter, and four small screw hole points labeled 4-ø4.2.

5.) Connect the speaker wires. The left terminal is Negative (-), the right terminal is Positive (+).
Line drawing step labeled with a circled "5" in the top-left corner, illustrating speaker wire connection: Speaker Housing: Shows the back side of a round speaker body resting upside down on its front flange. Wiring Connections: A black wire connects to the negative (-) spade terminal on the left side, and a red wire connects to the positive (+) spade terminal on the right side. Additional Details: Additional small wire leads extend from the upper-left side of the magnet enclosure.
6.) Change the speaker’s LED color by using the included jumper(A) to connect the red and black wires (B) for red LED color or the blue and black wires (C) for blue LED color.
Line drawing step labeled with a circled "6" in the top-left corner, showing how to connect an LED wiring harness plug: Main Diagram: The rear view of a speaker magnet assembly showing main power wires attached on the right and an LED plug terminal protruding from the center base. Inset A: Shows a schematic arrow indicating the male plug inserting straight into the matching female receptacle notch. Inset B & C: Close-up views highlighting the alignment of wire polarity: B: Red box outlines the connector housing showing the red and blue wires aligned with the corresponding pin positions. C: Close-up view showing the connector fully snapped into place over the terminal posts.
7.) Carefully insert the speaker into the opening and use the included mounting screws to secure it.
Line drawing step labeled with a circled "7" in the top-left corner, illustrating the final mounting of a speaker into a cutout: Speaker & Cutout: A circular marine/car speaker with a spoked grille pattern is shown angled toward a pre-cut round mounting hole. Wiring: A red wire extends from inside the dark circular mounting cutout to connect with the rear assembly of the speaker. Fasteners: Dashed directional lines point four Phillips-head mounting screws into corresponding screw holes on the outer rim of the speaker frame, guiding them into the mounting surface.

 

 

Speaker/Amplifier Configuration

Make sure that the positive (+) and negative (–) speaker wires are connected to the corresponding terminal on the amp.

  • Most speaker damage is caused by amplifiers with too much power (wattage).
  • The proper way to set your gain is to turn your receiver volume to max, and then slowly turn your gain up. The second you hear any slight distortion, turn it down one notch and leave it at that setting. Amps are not meant to be played with the gain up to the max. If this is the case, lower your gain slowly until you hear the amplifier stop clipping.
Technical line illustration showing the rear panel of a Rockville RXMT1 amplifier wired to two 4-ohm speakers: Amplifier Connections: CH1 Terminals: Connected to the left speaker. The positive (+) terminal uses a red wire, and the negative (-) terminal uses a black wire. CH2 Terminals: Connected to the right speaker. The positive (+) terminal uses a red wire, and the negative (-) terminal uses a black wire. Power Terminals (Right Side): Screw terminals labeled +12V, REM, and GND (unwired in this diagram). Text Markings: Notes near the speaker terminals read "MINIMUM IMPEDANCE 2-OHM STEREO, 4-OHM MONO BRIDGED". Speaker Connections: Left Speaker (4Ω): Red wire connects to the + terminal; black wire connects to the - terminal. Right Speaker (4Ω): Red wire connects to the + terminal; black wire connects to the - terminal.
