Not anymore apparently. After reading reviews and seeing dyno results I gave this tiny Amp a try. It didn't disappoint me. Putting out a true 65 watts per channel rms. I have it powering my 2 6 1/2 door speakers and 2 4" and 2 4x6 in the rear. Plenty to get the speakers moving. No clipping or engine noise. If your looking for a small Amp that will be enough to power your mids and highs, this Amp is perfect. Knowing the size I can and will use on my next motorcycle system Review: Small and powerful - This little lamp kicks butt! My aftermarket head unit wasn't quite cutting it for me, I found myself driving around with it cranked to the max all the time. It was rated it 60 watts per channel mute I'm sure that's Max, RMS was probably more like 15 watts. This amp was small enough for me to install it in the dash behind the head unit so wiring it to the factory harness was super simple. I'm using it to run four Skar Audio 6x8 4 ohm speakers in my Ford f150 so, according to the specs, it should be producing 66 wats per channel. I found it to be a little to powerful so I turned the gain down a bit to give me more precise volume control and I still don't need to turn it up to more than 1/2 to 3/4 volume to make my ears hurt. I am very pleased with this purchase as it does everything I needed it to do and then some. Great value for the money. ## Features - 400W total power output - Four channels for versatile speaker configurations - SounDigital car audio amplifier - Compact and durable design - Supports various speaker configurations ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09BZ8PNVR | | Best Sellers Rank | #9,674 in Electronics ( See Top 100 in Electronics ) #15 in Car Multichannel Amplifiers | | Brand Name | SounDigital | | Customer Reviews | 4.5 out of 5 stars 359 Reviews | | Included Components | Soun digital Amplifier and manual | | Item Dimensions | 4.33 x 4.33 x 1.97 inches | | Item dimensions L x W x H | 4.33 x 4.33 x 1.97 inches | | Manufacturer | SounDigital | | Material Type | Electronic Components | | Maximum Output Power | 400 watts | | Maximum Supply Voltage | 16 Volts (DC) | | Minimum Supply Voltage | 8 Volts | | Model | 400.4 EVO 4.0 | | Mounting Type | Speaker | | Number of Channels | 4 | | Output Power | 400 Watts | | Package Type Name | Box | | Part Number | SD 400.4 EVO 4.0 | | Specification Met | FCC | | Supply Current | 39 Amps | | Unit Count | 1.0 Count | | Voltage | 8 Volts (DC) | ## Product Details - **Item dimensions L x W x H:** 4.33 x 4.33 x 1.97 inches - **Manufacturer:** SounDigital - **Maximum Supply Voltage:** 16 Volts (DC) - **Minimum Supply Voltage:** 8 Volts - **Voltage:** 8 Volts (DC) ## Images ![Amplifier (400W 4 Channels) - Image 1](https://m.media-amazon.com/images/I/613oOlkCG6L.jpg) ## Questions & Answers **Q: Can i run 6 speakers to this that qre 4 ohm a piece?** A: Yes, 2 speakers per channel **Q: Can you run 2 channels mid and another channel for sub** A: I wouldnt recommend that.

I actually am using it passed thru my Fosgate RX500D amp....It is clean no humming no no hissing in the 2 RF P3 speakers I have in my back dash. I totally played myself by purchasing the Boss CE102 to drive the P3s which was an absolute disaster...that amp is so terrible it pushed interference thru my P3s and my 12" Kicker sub...I thought it was my grounds, RCAs, etc until I started process of elimination. SD EVO is clean and crisp and very small so concealing it is very easy...my only gripe is the speaker terminals are right next to the power terminals but they obviously did some expert engineering...again the lil thing sounds clean. ## Frequently Bought Together - SounDigital Amplifier (400W 4 Channels) - DteeDck RCA Splitter 1 Female to 2 Male, 2 Pack - RCA Audio Video Cable Splitter Adapter, Dark Blue - SounDigital - Car Full Range Amplifier 800 - 4 Channels 800 Watts RMS 4 Ohm - Compact Size - Professional Quality - 2025 Best Performance Award --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ph/products/416631942-amplifier-400w-4-channels](https://www.desertcart.ph/products/416631942-amplifier-400w-4-channels) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-06-04*
