MTX Marine Amplifiers Editorial Review
The MTX Audio WET75.4 400W RMS 4-Channel Class AB Marine Amplifier is a great option for those looking to enhance their marine audio system. According to customer reviews, this amplifier delivers excellent sound quality, especially for mids and highs. Unlike most class D amplifiers, the WET75.4 has no hiss, which is a big plus for music enthusiasts. One customer mentioned using this amplifier on their pontoon boat, and they had no issues despite having it installed under the deck next to water. This suggests that the amplifier is durable and can withstand marine conditions. However, a potential downside of this amplifier is that it tends to run hot due to its class AB design. Some users reported that it has a tendency to overheat. This is something to Consider, especially if you plan on using the amplifier for extended periods of time or in hot climates. In conclusion, the MTX Audio WET75.4 400W RMS 4-Channel Class AB Marine Amplifier is a reliable and high-quality option for enhancing your marine audio system, particularly for mids and highs. Its lack of hiss and ability to withstand water exposure make it a great choice for boating enthusiasts. However, it is important to be aware of its tendency to overheat.
