As much fun as it is to check out top-of-the-line products, sometimes the right solution is surprisingly affordable. The marine and powersport audio experts at Rockford Fosgate offer a full line of digital media receivers. In fact, there are five stand-alone units, plus an add-on multi-zone unit with several controller options. There is, indeed, a solution for every application. We will highlight the affordable but full-featured PMX-1 Punch-Series marine-grade receiver in this spotlight.
PMX-1 Physical Design
When we talk about source units, we usually discuss single or double DIN units designed for cars and trucks. The PMX-1 chassis, designed for marine and powersports applications, is intended to be flush-mounted on a flat panel. Rockford Fosgate has several vehicle-specific audio upgrade kits for side-by-sides that include mounting provisions for this unit.
The face of the PMX-1 is 4.5 inches wide and 4.2 inches tall. It protrudes 1.5 inches forward of the mounting surface, and the chassis and heatsink extend 2.9 inches rearward. The kit includes a rubber mounting gasket to ensure the face seals perfectly against the mounting surface.
The radio can be installed in one of two ways. If you have a dash with a round three-inch mounting hole, your installer can mount the radio using the supplied aluminum U-bracket, just like a speedometer or tachometer in a boat. Alternatively, the kit includes a metal mounting bracket that can be positioned behind the mounting surface, and four screws secure the display to the plate and sandwich on either side of the mounting surface. An included trim ring conceals the mounting hardware once in place.
The radio is rated to have an IPX6 water intrusion rating, so you can blast it all day long with a hose or let it get hit by waves. This is crucial in Rockford Fosgate’s Element Ready™ marine, motorcycle, and powersport products. Further, the radio has been tested to exceed prolonged UV and salt fog exposure requirements. Few, if any, other brands talk about the durability of the overall design. Rockford Fosgate punishes their Element Ready™ products with impact and vibration testing to ensure you’ll always have tunes when on the trails or ripping the waves.
User Interface Design
The first feature you will see when you look at the PMX-1 is its 2.3-inch dot-matrix monochrome display. While this looks simple, the display is constructed with a wet-bonded process that makes it easy to read in bright sunlight. The glass screen over the display has a 9H hardness rating, so it’s scratch-resistant. Many competing products use plastic over the display.
A sizable rotary encoder in the center of the front panel allows for volume adjustments or navigating through different menu settings. Four buttons on either side of the encoder provide direct access to source selection, track adjustment, play/pause, menu access, and a dimmer control. Bass heads will love that there are subwoofer + and – buttons on the front panel.
Rockford Fosgate PMX-1 Source Options
You have four options for playing music from the PMX-1. The built-in terrestrial radio tuner includes AM and FM reception capabilities. It also has a weather band tuner for those near larger lakes or the ocean.
You can connect a 32GB or smaller USB memory stick to the USB port to play MP3 or WMA files. The system supports up to 255 folders with a maximum of 1,000 songs.
The radio has stereo RCA input jacks on the back as a third option. So, if you want your installer to connect it to a laptop, DVD player, or similar device, it’s ready to go.
Finally, the PMX-1 includes a Bluetooth receiver. The system uses Bluetooth 3.0+EDR and supports the Advanced Audio Distribution Profile (A2DP) version 1.3. You can connect almost any smartphone and play music stored on it or stream audio from Pandora, iHeartRadio, or Spotify. Album and artist information will scroll across the screen if your device supports sending this information over Bluetooth.
Power, Preamp, and Installation Considerations
The radio includes a four-channel amplifier rated to produce 25 watts of continuous power into four four-ohm speakers with less than 1% THD+N. It also has two sets of RCA jacks on pigtails, rated to produce up to 2 volts of output.
The radio includes a three-zone crossover set to high or low-pass modes with 60, 80, or 120 hertz filter frequencies. The crossovers work on the built-in amplifier and the preamp signals. For the second set of RCA outputs, your installer can select between the rear and subwoofer output functions in a nearby menu.
The radio has a seven-band graphic equalizer with Flat, Rock, Classic, Acoustic, Dance, Electronic, and Hip-Hop presets. A custom EQ mode allows you to fine-tune the system to suit your audio system design or listening preferences. Of course, Rockford Fosgate includes their famous Punch EQ in the PMX-1. You can dial up to 18 dB of boost at 45 Hz and 12 dB at 12.5 kHz.
Power conservation can be a concern for marine and powersports vehicles, so the PMX-1 includes a battery voltage display, so you can keep track of things. The radio uses non-volatile memory to store all setting information. As such, it only requires an accessory and ground power connection. There is no clock, so your installer doesn’t have to hook up a wire likely to drain the vehicle battery. If you turn the radio off but leave it powered, it draws under two amps of current. At the other end of the spectrum, the radio has a 20-amp fuse, so ensure your installer uses large enough wiring to power it.
Compact and Durable Audio Solution
If you are looking for a reliable, easy-to-use radio for a boat, side-by-side, ATV, or jet ski, the Rockford Fosgate PMX-1 is an excellent solution. If you’ve had a craving to build a portable boombox from an old ammo can, the PMX-1 is perfect for that as well. You can pick up a PMX-1 at any authorized Rockford Fosgate dealer. You can find a dealer near you using the locator tool on their website.
