PYLE PLMRMP3 Hydra 4-Channel Amplifier
Installation Precautions
- Before you drill or cut any holes, investigate your vessel’s layout very carefully.
- Take special care when you work near the gas tank, fuel lines, hydraulic lines, and electrical wiring.
- Never operate the amplifier when it is unmounted. Attach all audio system components securely within the amplifier to prevent damage, especially in an accident.
- Do not mount this amplifier so that wire connections are unprotected, in a pinched condition, in contact with any metal surfaces in your marine vessel, or likely to be damaged by nearby objects.
- Before making or breaking power connections in your system, disconnect the marine vessel 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, replace it only with a fuse identical to that supplied with the amplifier. Using a fuse of a different type or rating may result in damage to your audio system or your amplifier, which is not covered by the manufacturer’s warranty.
- Don’t misuse the level control!
- Do not mistake the input level control for a volume control! It is designed ONLY to match the output level of your audio source to the input level of your amplifier.
- Do not adjust this input level to maximum unless your input level requires it.
- Ignoring these instructions will result in an input overload to the amplifier and excessive audio distortion. It can also cause the protection circuit to engage
Controls, Input, and Output Cables
The switches and gain settings are located behind a watertight plug, which also lights up when the amplifier is on. Be sure to replace the plug when finished with adjustments.
- 1. The INPUT LEVEL switch selects the input sensitivity of the amplifier. If you are connecting to a LINE level source (typically any RCA type connection) then the switch should be in the LiNE (out) position. When connecting to loudspeaker outputs or headphones or high level sources then set the switch to the SPEAKER (in) position.
- The POLARITY switch allows the user to optimize bass performance in the case that there are more than 1 set of loudspeakers producing bass in the system. Play some music with strong bass content and listen with the switch alternately in the NORMAL and REVERSE positions until it can be determined which setting results in more pleasing bass response. If in doubt, or if any interaction with other speakers is unlikely, then leave the switch in the NORMAL position.
- The GAIN control adjusts the overall level of the amplifier. When using the amplifier without volume control, the level should be set to achieve a balance with other loudspeakers in the system. As a rule, keep the gain setting as low as possible while still ensuring that the system will reach full output power. When using the system with external volume control, set the external Volume Control to FULL (clockwise) and adjust the gain on the amplifier until full output power is reached. The full output power level can be determined by turning the gain control clockwise until the apparent loudness does not appear to increase anymore. Leave the control at the setting where this begins to become apparent.
- VOLUME CONTROL Plug for the waterproof remote volume control. When installed, this control will turn off the Marine Amplifier Kits when turned all the way down.
- INPUT Stereo RCA audio input for connecting other audio devices.
- To Connect Bluetooth
- Turn on the amplifier, the red Bluetooth indicator LED keeps blinking at this moment.
- Look for the “Bluetooth” function in your phone settings and open it.
- Search for the Bluetooth device which is “pyle amplifier”. After you connect the Bluetooth successfully, the red Bluetooth indicator LED will stay on. Bluetooth Version: 3.0 Only models PLMRMB4CW and PLMRMB4CB feature built-in Bluetooth.

PYLE PLMRMP3 Hydra 4-Channel Amplifier-FAQs
Can the Pyle Hydra amplifier be bridged?
Yes, the PYLE Hydra marine amplifier is bridgeable, allowing it to combine channels for more power. It’s compatible with both high and low-level inputs, making it versatile for various audio sources.
How many speakers can I connect to the Pyle speaker selector?
Using the Pyle PSS4 Stereo Speaker Selector, you can connect up to four individual pairs of speakers and control them independently — great for multi-room setups.
Does Pyle offer Bluetooth-enabled devices?
Yes, Pyle offers Bluetooth-enabled speakers, such as their 8″ 700W PA speakers, which support wireless audio streaming and come with stands, remotes, and power cables.
What is the Bluetooth pairing code for Pyle devices?
Most Pyle Bluetooth devices will pair automatically, but if prompted for a PIN, enter “0000”.
Will a 4-channel amplifier increase speaker volume?
Absolutely. A 4-channel amp can significantly boost the power going to your speakers, enhancing volume and sound quality without needing to change the head unit or speakers.
What are 4-channel amplifiers typically used for?
A 4-channel amp is ideal for powering multiple speakers in different zones or rooms. It’s perfect for creating immersive audio setups with precise speaker placement.
How many speakers can a single amplifier support?
An amplifier can power multiple speakers as long as the total speaker impedance stays within the amp’s supported range. Always check the amp’s specs to avoid overloading.
Can I connect 4 speakers to a 2-channel amp?
You can, but it must be done carefully. If the combined impedance drops too low (e.g., below 4 ohms), the amp might overheat or activate its protection mode.
What does the gain control on an amplifier do?
The gain adjusts the input sensitivity of the amp to match the output level of your head unit. It ensures clear, distortion-free sound by balancing input volume.
