Better buy the best speakers available, or they won’t last 3 seconds into anything. Smoked 3 sets of 200$ speakers until I installed the Audiolegion 6”- they scream. Review: Great amp - This amp is very strong to say the least. I have it bridged pushing two kicker km8's and it easily maxes out the speakers. Only down side is it seems to go very heavy on the bass when in full range and you cant really adjust it down so a phone equalizer app will be needed. Overall an awsome amp. EDIT.... ok so after having this a few months i went to open my wifes speaker box and somehow water got inside the box. This amp got VERY WET insode and out but all i did was let it dry out in the sun for 2 day and bam it still works like a champ haha. I love this amp for real. You get what you pay for haha. ## Features - INSTALL IN THE TINIEST OF SPACES: Compact design and small footprint chassis allows for installation in space challenged vehicles - WEATHER-PROOF DESIGN: Conformal coated circuit board is protected against corrosion or circuit deterioration due to exposure to moisture or salty conditions - WIDE RANGE OF ABILITY: Fixed high and low pass crossovers allow use with full-range speakers or subwoofers - HIGH AND LOW-LEVEL INPUTS: High and low-level inputs allow for connections to both speaker and RCA input signals - CONVENIENT PIGTAIL CONNECTION: Includes a pigtail that contains all of the wiring necessary to connect power, ground, and signal without having to make a connection directly at the amplifier ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01DAYDY64 | | Best Sellers Rank | #414 in Powersports Speaker Systems | | Brand | MTX | | Customer Reviews | 3.8 3.8 out of 5 stars (43) | | Date First Available | March 22, 2016 | | Is Discontinued By Manufacturer | No | | Item Weight | 3.14 pounds | | Item model number | MUD100.4 | | Manufacturer | MTX | | Material | Plastic | | Maximum Supply Voltage | 16 Volts | | Minimum Supply Voltage | 12 Volts | | Mounting Type | Surface Mount | | Number of Channels | 4 | | Output Power | 400 Watts | | Package Type Name | Box | | Specification Met | RoHS, WEEE | | UPC | 715442241934 021100929985 | | Voltage | 400 Volts | | Warranty | 2-Year Manufacturer Warranty | | Wireless Remote | No | ## Product Details - **Manufacturer:** MTX - **Maximum Supply Voltage:** 16 Volts - **Minimum Supply Voltage:** 12 Volts - **Mounting Type:** Surface Mount - **Voltage:** 400 Volts ## Images ![MUD100.4 Mud Series 400 Watt RMS 4 Channel Class D Compact Weatherproof Outdoor Powersports ATV UTV Motorcycle Sound System Stereo Amplifier Kit - Image 1](https://m.media-amazon.com/images/I/61LvSgjRS+L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ POWERFUL *by G***R on 15 November 2021* Amazing sound and power. Better buy the best speakers available, or they won’t last 3 seconds into anything. Smoked 3 sets of 200$ speakers until I installed the Audiolegion 6”- they scream. ### ⭐⭐⭐⭐⭐ Great amp *by A***E on 3 March 2020* This amp is very strong to say the least. I have it bridged pushing two kicker km8's and it easily maxes out the speakers. Only down side is it seems to go very heavy on the bass when in full range and you cant really adjust it down so a phone equalizer app will be needed. Overall an awsome amp.

This amp got VERY WET insode and out but all i did was let it dry out in the sun for 2 day and bam it still works like a champ haha. I love this amp for real. You get what you pay for haha. ### ⭐⭐⭐⭐ Rear channel blew out. *by C***E on 16 October 2022* Sound was great. It then took time to figure out why my rear channels weren't working, I took the seals off the amp volume controls and the rear light was off when it should be on like the front amp switch. I paid to have the sound system installed in my boat. ## Frequently Bought Together - MTX MUD100.4 Mud Series 400 Watt RMS 4 Channel Class D Compact Weatherproof Outdoor Powersports ATV UTV Motorcycle Sound System Stereo Amplifier Kit - MTX AWBTSW Bluetooth Rocker Switch Receiver and Control - MTX MUD65PL Mud Series 6.5 Inch 50 Watt RMS Handlebar Cage Mount Weatherproof Coaxial Motorcycle ATV UTV Speaker Pair with RGB LED Lights --- ## 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.tw/products/344873790-mud100-4-mud-series-400-watt-rms-4-channel-class](https://www.desertcart.tw/products/344873790-mud100-4-mud-series-400-watt-rms-4-channel-class) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-09-06*
