    Input Options

    The PLMRA420 features gold-plated low-level RCA inputs for sources that use RCA-type connectors. If your marine receiver lacks RCA output jacks, you can connect speaker output leads to the high-level MOLEX inputs.

    Input Level Control

    Adjust the line level input for the least amount of distortion to match your source unit.

    Bass Boost

    Add a little low-end boost with selectable bass boost of up to approximately 18dB at 60Hz.

    High- and Low-Pass Filters

    Optimize the output to match your speakers exactly, using the variable high-pass and low-pass frequency controls.

    Crossover Mode Selector

    Route the output of the low-pass or high-pass filters or the full signal to the internal power amplifier, or the full range if preferred.

    Protection

    Protect the amp and your vehicle's electrical system from short circuit conditions with built-in fuse protection, along with overload, thermal and short circuit protection. LED lights indicate if the amp has gone into a protection mode. Finally, an anti-thump turn-on feature protects your speakers during power-up.

    Good Value Amplifier ! Smaller Input terminals make wiring power cables difficult
    I purchased this for my Lund 14 ft Aluminum Boat to go along with my Boss Audio MGR350B head unit and 2x Pyle 75w speakers, 2x 100 watt 6.5" speakers. I was satisfied with the stock performance of the speakers and head unit but the speakers just wouldn't get loud enough to hear when I was running the boat on full throttle. After installing the Pyle Amplifier I noticed an immediate gain in volume, bass, and overall performance. There are only 3 things I would change about the Amplifier. The power in terminals are very small and I had difficulty finding the proper terminal connectors to go with the 4AWG wire I was using ( MFG recommends min 6 AWG wire). The terminals are just too small to be connecting wiring this large. I had to take a 4AWG 1/4" Lug connector and slightly grind down the sides to get it to fit in the slot. The Amplifier is also fairly large in size and I found the lights on top of the unit to be a bit distracting and I wish I could turn them off because at night they can be very annoying. Also, the instruction booklet indicates that all the mounting screws and hardware are included but I didn't receive anything in the box. Other than those very minor issues ( the power input design being the worst issue) I would highly recommend this unit to anyone. Be sure to read the instructions very carefully and make sure you're using the proper size speakers and wiring them correctly otherwise you can damage your speakers/amp.

    5.0 out of 5 stars Great little amp for the money
    Reviewed in the United States on February 23, 2024
    For the money, I'm not sure how anyone could complain about this amp. I installed this one to replace my old kenwood amp, which finally bit the dust. This one was simple to install and it very nicely powers my 10 inch sub and two 6.5 inch waketower speakers to go along with the house speakers in my boat which run through the head unit. It provides plenty of power. Clear and LOUD. I think anyone who gives this thing a negative review must not be thinking clearly about the price of this thing. Are there better marine amps out there? Of course, for 6 or 7 times the price of this one. Even if I have to replace this thing every two years, its less than 100 bucks! My only knock on it is that it doesn't have an input for my remote subwoofer control.

    5.0 out of 5 stars Unbeatable bang for the buck
    Reviewed in the United States on July 7, 2023
    I was looking to do a budget stereo system upgrade on our new boat. After doing a lot of research I decided to buy the Pyle PLMRA420 amp along with 4 Pyle PLMR62 6.5” 2 way speakers. Including wiring I have a bit over $200 (amp was on sale for $100 and the speakers were $35.98 per pair) and a few hours of my time wrapped up in the system. The sound is excellent, the price point can’t be beat and the overall visuals of how the amp and speakers look is awesome. I’m going to add a set of wake tower speakers in the next week or so to complete my system. At that point I’ll run the four 6.5” speakers off of channels 1&2 and run the wake tower units off channels 3&4. I could probably leave the system the way it is now and be completely happy with the sound it puts out but I really to finish things off with a set of LED wake tower speakers. Take your time setting the amp up. It’s well worth the few extra minutes to get great sound quality in the end at an absolute bargain price point.

    Overall great bang for the buck.
