Man kann über des beigefügte Kabel MP3 Player o.Ä. anschließen, benötigt aber dafür ein extra Klinkenkabel. Ein Drehknopf wird angeschlossen, mit dem man den Verstärker ausschalten kann (allerdings regelt dieser nicht die Lautstärke, was ich etwas seltsam finde), eine richtige Fernebdienung ist nicht enthalten. Zudem gibt es eine Hülle für das Handy/MP3 Player, die wasserdicht ist.Ob der Verstärker wirklich wasserfest ist habe ich noch nicht getestet, mir ging es hauptsächlich darum 4 Kanäle zu haben und das bei einer kompakten Größe. Diese Voraussetzungen wurden erfüllt. Der Klang mit dem Verstärker ist ordentlich, könnte aber besser sein (wobei man bei dem Preis definitiv auf dem Teppich bleiben sollte was die Erwartungen angehen), es gibt kein Rauschen, der Klang ist klar (bitte auch bedenken, dass die angeschlossenen Lautsprecher einen großen Einfluss haben).Insgesamt bin ich zufrieden und ich würde das Produkt wieder kaufen. ### ⭐⭐⭐⭐⭐ I bought this because the inbuilt amplifier in my head ... *by J***R on Reviewed in the United Kingdom on 10 March 2015* I bought this because the inbuilt amplifier in my head unit shut down.What I found it tht the sound is punchier, more open and musical than the inbuilt chipsets claiming to be the same output power.Quality is high and the inclusion of much of the cabling makes for a simple installation. ## Frequently Bought Together - Pyle 400W 4-Channel Hydra Marine Micro Amplifier - Waterproof - RCA Input - 3.5mm Jack - MP3 - Soft Turn On/Off - Volume Gain Level Remote Control - Power Protection - PLMRMP3A - Pyle 6.5 Inch Dual Marine Speakers - 2 Way Waterproof and Weather Resistant Outdoor Stereo Sound System with 400 Watt Power, Polypropylene Cone and Butyl Rubber Surround - 1 Pair - PLMR605W(White) - Pyle Marine Bluetooth Stereo Radio - 12V Single DIN In-Dash Receiver for Boat Audio with Built-In Mic - Digital LCD - MP3/USB/SD Playback - AM/FM Radio - RCA Output - Remote Control - PLMRB29W --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/280915779-hydra-marine-amplifier-upgraded-elite-series-400-watt-4-channel](https://www.desertcart.us/products/280915779-hydra-marine-amplifier-upgraded-elite-series-400-watt-4-channel) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-13*
