About
6 CHANNEL BRIDGEABLE AMPLIFIER: Pyle’s PLMRA620 is engineered as a 6 Channel bridgeable marine amplifier that powers up your speaker and is universally compatible. It has a bridge mode selection switch and high or low electronic crossover network WATERPROOF & WEATHERPROOF:
The audio amplifier is waterproof with its marine grade rating of IP-01. It’s constructed with gold-plated stereo speaker output terminal connectors to combat weather corrosion with long-term us SHORT PROTECTION: Built with a heavy-duty Aluminum Alloy heatsink, thermal overload speaker short protection, and LED light indicator. These are to protect the amp and your vehicle’s electrical system from short circuit conditions POWERFUL 2000 WATT: This amplifier receiver is powerful with its 2000 WATT MAX and dual MOSFET power supply. Comes with dual adjustable input GAIN level controls between 4 to 8 Ohm speaker impedance RCA STEREO INPUT: For easier use of this hydra marine amplifier, it comes with premium RCA inputs.
If your marine receiver lacks RCA output jacks, you can connect speaker output leads to the high-level terminal inputs 4 x 100W + 2 x 250W RMS @ 4 Ohms – Variable Bass Boost (CH5 / CH6) – Remote Bass Boost – Variable Input Level (Gain) Control 4 x 250W + 2 x 500W MAX @ 4 Ohms – 2 Ohm Stereo Stable – Blue LED Level Display – Thermal / Overload / Short Circuit Protection

Mounting and installation
Your new Pyle Marine Series amplifier comes complete with all required mounting hardware. When determining a suitable location in your vehicle for the amp, please remember that it is a high-power electronic device capable of generating high heat. For this reason, always choose a location in your vehicle that has low vibration, adequate ventilation, a minimum of dust, and no moisture. Be sure to mount the amp in such a manner as to allow reasonable airflow over the cooling fins.
Mark the location for the mounting screw holes by positioning the amp where you wish to install it and use a scribe (or one of the mounting screws) inserted in each of the mounting holes to mark the mounting surface. If the mounting surface is carpeted, measure the hole centers and mark them with a felt tip pen. Before attempting to drill the mounting holes, take note of any wires, lines or other devices in your vehicle which may be located behind the mounting surface! Then drill pilot holes in the mounting surface for the mounting screws and insert them. Tighten the screws securely.
wiring tips when making electrical connections to your amplifier, please observe the Use of at least 8 gauge wire for power and ground connections. Wire the amplifier directly to the car battery. For the ground connection, use the shortest possible wire to a good chassis ground point. Wire the Remote connection to the auto start lead of your head unit, equalizer, or power antenna.
About power fuses:
Pyle Marine Series amplifiers feature built-in fuse systems. These fuses protect both the amplifier and the electrical system in your vehicle from fault conditions. If you ever need to replace the fuse in your Pyle Marine Series amp, use a fuse of exactly the same type and rating. A different type or rating of fuse may result in damage or fire.
Troubleshooting
No output. Confirm that all terminal strip connections are secure and tight. Check both in-line and built-in fuses. Both the +12V and the Remote terminals must have +12v referenced to chassis ground. Confirm that the audio signal source (car radio, equalizer, etc.) is connected and is supplying the output signal. To check if the amp is supplying a signal, unplug the cables from the signal source (but leave them plugged into the amp). Briefly tap the center pin of each of the disconnected RCA plugs with your finger. This should produce a noise (feedback) in your speakers.
Only one channel works. Confirm that all terminal strip connections are secure and tight. Check the Balance control on the head unit (or another source) to verify that it is set to its midpoint. If you are using the Low-Level RCA input, reverse the input plugs at the amplifier (i.e., switch the L with the R). If the channels which are silent switch to the other side, the problem is either in the head unit/other source or the connecting cables.
Weak output. Readjust the Input Level Control(s) to better suit the input signal. Noise in the audio. If the noise is a “whine” whose pitch follows the engine speed, confirm that the amplifier and any other signal sources (head unit, etc.) are properly grounded. If the noise is a “clicking” or “popping” noise whose rate follows the engine speed, this usually means that the vehicle is equipped with resistor spark plugs and wires, or that the ignition is in need of service. Check the mounting of the speaker and input wires to make sure they are not adjacent to wires which interconnect lights and other accessories. If the above steps fail to improve or clear noise interference, the system should be checked by a professional mobile audio installer.
Precautions
Do not operate the amplifier when it is unmounted. Attach all audio system components securely within the automobile to prevent damage, especially in an accident. Do not mount this amplifier so that the wire connections are unprotected, or in a pinched condition, or likely to be damaged by nearby objects. Before making or breaking power connections in your system, disconnect the vehicle battery. Confirm that your head unit or other equipment is turned off while connecting the input jacks and speaker terminals.
If you need to replace the power fuse, do so only with a fuse identical to that supplied with the amplifier. Using a fuse of a different type or rating may result in damage that isn’t covered in the manufacturer’s warranty.
