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. ## 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 | #254,982 in Electronics ( See Top 100 in Electronics ) #23 in Car Multichannel Amplifiers | | Brand Name | SounDigital | | Country of Origin | USA | | Customer Reviews | 4.6 out of 5 stars 339 Reviews | | Included Components | 1 | | Item Dimensions | 11 x 11 x 5 Centimeters | | Item dimensions L x W x H | 11 x 11 x 5 Centimeters | | Manufacturer | SounDigital | | Material Type | Electronic Components | | Maximum Supply Voltage | 16 Volts (DC) | | Minimum Supply Voltage | 8 Volts | | Model Number | 400.4 EVO 4.0 | | Mounting Type | Speaker | | Number of Channels | 4 | | Output Power | 500 Watts | | Package Type Name | Box | | Part Number | SD 400.4 EVO 4.0 | | Specification Met | FCC | | Supply Current | 39 Amps | | Voltage | 8 Volts (DC) | ## Product Details - **Item dimensions L x W x H:** 11 x 11 x 5 Centimeters - **Manufacturer:** SounDigital - **Maximum Supply Voltage:** 16 Volts (DC) - **Minimum Supply Voltage:** 8 Volts - **Voltage:** 8 Volts (DC) ## Images ![SounDigital Amplifier (400W 4 Channels) - Image 1](https://m.media-amazon.com/images/I/61zT2sWsEsL.jpg) ![SounDigital Amplifier (400W 4 Channels) - Image 2](https://m.media-amazon.com/images/I/61fAmkOGACL.jpg) ![SounDigital Amplifier (400W 4 Channels) - Image 3](https://m.media-amazon.com/images/I/61gyXFIw4pL.jpg) ![SounDigital Amplifier (400W 4 Channels) - Image 4](https://m.media-amazon.com/images/I/51hv3rrthnL.jpg) ![SounDigital Amplifier (400W 4 Channels) - Image 5](https://m.media-amazon.com/images/I/51B28o3OO6L.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.
