The Audison design team, headquartered in the Potenza Picena (Italy), spent a long time planning and perfecting the new SR line, taking full advantage of the features that the most recent amplification devices available today are equipped with. After numerous listening tests in a double-blind configuration on a significant sample of professionals and enthusiasts, the R&D team decided to adopt a new D-class technology called ADT (Audison D-Class Technology) for the whole range, which made it possible to reduce the size of the amplifiers considerably, totally preserving the audio performance that characterize each Audison project. As for the electronics design, the Audison style center has taken care of every aesthetic and functional detail, obtaining a compact amplifier made of extruded aluminium with rounded corners that ease the installation of the product in narrow spaces. Thanks to the generous heat sinks on the two short sides of the amplifiers, internal cooling fans are not necessary, which are often cause of noise and dust accumulation. Features - ADC (Audison D-Class) Technology 2Ω stable output stage ensuring high audio performance in a compact size. Extruded aluminum compact design with fanless convection cooling system. Built-in USS (Universal Speakers Simulator). Balanced high-noise rejection input speaker-In (for OEM head units) and RCA-In (for After-market head units) inputs. ART (Automatic Remote Turn-On/Off) automatically turns on/off the amplifier when the OEM head-unit turns on/off (can be enabled/ disabled, with Speaker-In inputs). Pre-outs, also available when using Speaker-In level inputs ## Features - Power supply voltage / fuse 11 ÷ 15 VDC / 1 x 30A - Operating power supply voltage 6.5V ÷17 VDC - Idling current 1.6 A - Idling current when off 0.03 mA - Consumption @ 14.4 VDC, 2Ω, Max Musical: Power 25 A ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B082X56RWC | | Best Sellers Rank | #277,189 in Electronics ( See Top 100 in Electronics ) #701 in Car Multichannel Amplifiers | | Brand | Audison | | Brand Name | Audison | | Customer Reviews | 4.2 out of 5 stars 20 Reviews | | Included Components | SR4.300.1-UOB | | Item Weight | 4 Pounds | | Manufacturer | Audison | | Material Type | Aluminum | | Maximum Supply Voltage | 17 Volts (DC) | | Minimum Supply Voltage | 6.5 Volts | | Model | SR 4.300 | | Mounting Type | Surface Mount | | Number of Channels | 4 | | Output Power | 520 Watts | | Part Number | 66740315 | | Specification Met | Adt | | Supply Current | 1.6 Amps | | Unit Count | 1.0 Count | | Voltage | 5 Volts | ## Product Details - **Manufacturer:** Audison - **Maximum Supply Voltage:** 17 Volts (DC) - **Minimum Supply Voltage:** 6.5 Volts - **Mounting Type:** Surface Mount - **Voltage:** 5 Volts ## Images ![SR 4.300 D-Class 4-Channel Amplifier 130 Wrms X 4 At 2-Ohms - Image 1](https://m.media-amazon.com/images/I/61epN45Y49L.jpg) ![SR 4.300 D-Class 4-Channel Amplifier 130 Wrms X 4 At 2-Ohms - Image 2](https://m.media-amazon.com/images/I/61SD6hLjnfL.jpg) ![SR 4.300 D-Class 4-Channel Amplifier 130 Wrms X 4 At 2-Ohms - Image 3](https://m.media-amazon.com/images/I/71FppOHhLGL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by J***8 on December 25, 2023* ### ⭐⭐⭐ Review *by D***N on August 30, 2024* ### ⭐⭐⭐⭐ Review *by B***N on September 23, 2023* ## Frequently Bought Together - Audison SR 4.300 4 Channel D-Class Amplifier 4X85 WRMS at 4 Ohms SR4300 - Audison SR1.500 D-Class Amplifier Mono Amplifier 1Ω 1000 W x 1 SR1500 - Audison SR 4.500 4 Channel D-Class Amplifier 880 Watt Amp SR4500 --- ## 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.id/products/231636786-sr-4-300-d-class-4-channel-amplifier-130-wrms](https://www.desertcart.id/products/231636786-sr-4-300-d-class-4-channel-amplifier-130-wrms) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-05-08*
