MS525 – 5.25˝ 2-Way Marine Speakers

Installation

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

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

Left Side: A left hand rests flat against the lower-left section of the paper template to hold it steady. The template is taped down at all four corners and clearly displays the "ROCKVILLE MS525" branding at the top. Right Side: A right hand holds a cordless power drill, pointing the drill bit directly at one of the marked target points along the inner circular measurement line labeled "137mm / 5.39in".

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

Left Side: A left hand is pressed flat against the lower-left section of the template to hold it firmly against the surface. Right Side: A right hand holds a utility knife (box cutter), placing the tip of the blade into a freshly drilled hole to begin cutting along the outermost circular line marked "177mm / 7in". Template Markings: The sheet is taped at all four corners and shows "ROCKVILLE MS525" printed at the top. Three black circular dots indicate drilled pilot holes placed along the concentric measurement lines (labeled 177mm / 7in, 163mm / 6.4in, and 137mm / 5.39in).

5.) Carefully insert the speaker into the opening and use the included mounting screws to secure it.

Black-and-white line illustration labeled "5" in a black circle at the top-left corner. The diagram shows the final assembly steps for mounting the speaker into a surface opening. Main Action: A circular speaker with a slatted front grille and central tweeter is shown directly in front of a dark, round mounting cutout. Fasteners: Four screws are positioned around the outer rim of the speaker face, aligned with the mounting holes. Alignment: Dashed black arrows point from each screw toward its corresponding hole on the outer flange of the speaker housing to show the direction of installation.

Speaker/Amplifier Configuration

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

A black-and-white wiring diagram showing the back panel of a Rockville XMRT1 amplifier wired to two 4-ohm round speakers to achieve a bridged mono connection. Amplifier Terminals: On the left side of the amplifier panel, the speaker outputs are labeled "+ CH1 - " and "+ CH2 -". Text nearby notes "MINIMUM IMPEDANCE 2-OHM STEREO, 4-OHM MONO BRIDGED". Speaker 1 (Left): A 4-ohm speaker labeled with positive (+) and negative (-) terminals. A positive wire connects from the amplifier's +CH1 terminal to the positive terminal of the left speaker, and a negative wire connects from the +CH1 adjacent -CH1 terminal to the negative terminal of the left speaker. Speaker 2 (Right): A second 4-ohm speaker labeled with positive (+) and negative (-) terminals. A grey wire runs from the +CH2 terminal on the amplifier to the positive terminal on the speaker, and a black wire runs from the -CH2 terminal to the negative terminal. Power Terminals: The right side of the amplifier panel features power connections labeled +12V, REM (remote), and GND (ground), alongside a fuse slot in the center.
