Hydra Marine Amplifier - Upgraded Elite Series 240 Watt 4 Channel Audio Amplifier - Waterproof, 4-8 Ohm Impendance, GAIN Level Controls, RCA Stereo Input & LED Indicator (PLMRA120)

I needed a compact but powerful amp to power two 8-ohm 25-watt RMS power horn PA speakers mounted in my show car to play sound effects. I first tried the Pyle PFA300 90-Watt amp I already had (running my garage stereo) but it wasn't loud or clear enough, so I decided to try this amp, as it is rated for approximately 35 Watts RMS - slightly more than what the speakers are rated for, but I wouldn't be powering them at max volume.I am very happy with the quality and volume of sound this outputs for its size. I was hoping the level control knob would act like a volume control and go 0-10, but in reality it has a narrow range and can't completely turn it down, but that's not a big issue. I can't speak for its long term reliability, and the "waterproof" aspect of the amp is pretty laughable, but so far I am very happy with this amp's performance.

I installed this amp in an ice-chest radio I built from scratch. It's loud! I love it. I took it onto the Guadalupe River and the entire ice chest went under water. I drained it out, let it dry, and miraculously the amp still fired up! This has happened on several occasions and she just keeps on working. This amp is about as waterproof as it gets. It's easy to work with, easy to setup, and sounds great. Best investment I could've made.

This amplifier arrived in two days and I installed it along side a Clarion APX480M in my Super Air Nautique SV-211.This amplifier does well for the cost, however in hindsight I will probably upgrade to the higher-wattage version. The sound is clean, the installation was easy, and this seems to do a reasonable job. After peeling back the layers though, I simply cannot see how this amplifier is waterproof in any way form or fashion. For a boat where you are putting this under a seat that wouldn't normally be exposed (directly) to getting splashed or drenched, this is a good choice. If you are going to constantly have this exposed to water, there are other options that are likely better.

Amp will not power up. Had to go to Walmart and purchase one that worked. Disconnected the Pyle amp and connected the new Sony amp in the parking lot. Proved my wiring was good because the Sony worked perfectly. Will be returning the Pyle for a refund.

Bought an old truck that came with a "Sound System" consisting of and old 12" sub, amp and some 5x9s. All of it rusted, blown and needing replacement. Did not feel the need to go big as I like music and my hearing, and I didn't want to spend a lot of money. I paired this tiny inexpensive amp with a low profile box I also found on Amazon(~$70.00). Box has 2x10s and 2x 5" tweeters. I split from rear speaker wires to high input plug. Then from amp to speakers. Amp is at 25% and everything is plenty loud. If you were looking for some competition speakers, or wanted to impress your friends, then this probably isn't for you. If you want some extra sound and don't want to tax your Head Unit this was fine for me.Speaker box I mentioned earlier: XXX Kic 100https://www.amazon.com/New-XXX-Audio-Subwoofer-Tweeters/dp/B003160K4G/ref=sr_1_1?crid=YGFHID9UV8K0&dib=eyJ2IjoiMSJ9.bKFpnzmNueN3k8uV5fxXiUalOub5H0NoNgi5KWjexro._fMrGMfDUtE5Df8zarHZ0Alyb0zHOgkEtmQYDMEhUvo&dib_tag=se&keywords=Xxx+kic100&qid=1708216080&sprefix=xxx+kic100%2Caps%2C253&sr=8-1

Well, overall this amplifier works. It isn't a bass thumpin', tweeter screamin' amp, but it does increase the volume of your music and is pretty clear. My big issue is how difficult the installation was.....it didn't come with the auxiliary inputs! I made it work, but since it did not come with the any auxiliary (radio head) input, I had to cut, crimp and solder adapters....made by me (and that ain't pretty.) I understand this is not a top dollar amplifier, but I do expect it to come with the equipment that is stated to come with it!Overall, not bad for the cost, but awful due to the "packaging." I actually saw that this is common for this particular product.

Great amp! Using it with Pyle PLMRB29W marine stereo 6.5" 2 way marine speakers PLMR62 and it sounds great! For around $100 bucks it is a really good setup and the quality and loudness is better than expected. I highly recommend this for anyone that wants a decent system and doesnt want to spend a fortune on some marine tunes.

I needed to replace an existing amp that had been under the seat of my Jeep Wrangler for a long time. It was a conventional amp and had suffered from exposure much like it would have in a boat. I needed a compact replacement that was water resistant so a marine amp was in order and the price for this unit was excellent. It was a snap to install (using existing wiring and speakers). The sound quality is excellent and there's plenty of power to overcome the road noise inherent in a Wrangler. I couldn't be happier with it.
