I returned for an infinity 600.4. The infinity sounded great but clips before my speakers. This HL800.4 is solid and the price per what you are inheriting is awesome.. my SUV is so full of sound and the gain isn't even halfway up! I'm running 4pioneer coax/4tweeters silk dome/two 8ohm satellite cubes and this thing is taking it with no issue. My sub amp is pushing two 12 pioneer champion series at around 650rms. The plan is to upgrade the subs to run a clean 1300rms and have the mids and hi's keep up! I think we found the one! 120+rms at 4ohm per channel. This thing is sick! No ground loop noise or engine whine. I do hear a light hiss from some really cheap tweeters at min volume but cheap tweeters are boosted at rest to get loud fast. I have a set of Rockville tweeters that were under 30.00 installed and they do not hiss so it doesn't require a super high dollar tweeter just something in the 30-40 dollar range. 👍 👍 Update 3/20/24 Amp still works like new! I torched a few tweeters and reran some wires to place all 4 6x8s and 2 tweeters and two cubes on two channels and then bridged a rf 2ohm sub and this thing is not breaking a sweat. its very versatile. The hiss I hear is from the built in fan but i dont mind it. Just hear it at resting volume but when volume increases you cant tell its there. May reduce to just 4 powerful 6x8s and super tweeters soon. now have two 12 inch ct sound stratos and they want about 1300rms per sub. Sound amazing on 1500rms between the two but too much headroom. Highly recommend this HL800.4 its a beast Review: Great little and powerful - I have this running 6 Ds-18 tweeters turned way down and puts out great sound. Only grip is the knobs to adjust are hard to turn with fingers had to get needle nose players to turn. ## Features - Channel: 4 channel - Input and Output Options: RCA input - Power Output: 800 Watts RMS car audio amplifier - Impedance Compatibility: 2 Ohm Stable, Full Range, Speakers & Subs - Equalization and Sound Control: Crossover, Bass Boost, HD Sound Quality ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B075TJ6VW5 | | Best Sellers Rank | #291,893 in Electronics ( See Top 100 in Electronics ) #688 in Car Multichannel Amplifiers | | Brand Name | Stetsom | | Customer Reviews | 4.4 4.4 out of 5 stars (162) | | EU Spare Part Availability Duration | 5 Years | | Global Trade Identification Number | 07897748704047 | | Included Components | Amplifier | | Item Dimensions | 8.66 x 8.27 x 2.76 inches | | Item Type Name | Amplifier | | Item Weight | 1.7 Kilograms | | Manufacturer | Stetsom | | Material Type | Aluminum | | Maximum Output Power | 1040 | | Maximum Supply Voltage | 15 Volts (DC) | | Minimum Supply Voltage | 9 Volts (DC) | | Model | HL800.4-2 | | Mounting Type | Surface Mount | | Number of Channels | 4 | | Operating Temperature | 55 Degrees Celsius | | Output Power | 800 Watts | | Package Type Name | Retail box | | Part Number | HL800.4-2 | | Specification Met | [Generic] | | Supply Current | 88 Amps | | Voltage | 15 Volts | ## Product Details - **Item dimensions L x W x H:** 8.66 x 8.27 x 2.76 inches - **Manufacturer:** Stetsom - **Maximum Supply Voltage:** 15 Volts (DC) - **Minimum Supply Voltage:** 9 Volts (DC) - **Voltage:** 15 Volts ## Images ![Stetsom Digital Amplifier 800W 4 Channel 2 Ohms - Image 1](https://m.media-amazon.com/images/I/81MsaBCMrSL.jpg) ## Questions & Answers **Q: Can i run six 8 inch prv 8mb450 8ohm speakers with this amplifier or should i get something bigger** A: Since you have 8 ohms speakers it would not be best to load them on a 4 channel amplifier because of the impedance, the amplifier will not provide enough power to them. The best way to provide them power is a PRV SQ3500X at 1ohm! You need to wire all 8 speakers in parallel to 1 ohm. **Q: 4 channels w/3 outputs, does it share power across left & right channel. I set gain by ear, l/r diff. Voltage with dmm but equals bridge power of amp?** A: The red light was on once I connect the amp, and the new apm is working perfect **Q: 800watts por cada canal? Oh 800 watts por todo** A: Son 800 Watts en total. Estas son las configuraciones posibles: Potencia RMS en 2 ohms 12.6 V 4 x 225 W RMS (ESTÉREO) Potencia RMS en 4 ohms 12.6 V 4 x 140 W RMS (ESTÉREO) Potencia RMS en 2 ohms 13.8 V 4 x 260 W RMS (ESTÉREO) Potencia RMS en 4 ohms 13.8 V 4 x 165 W RMS (ESTÉREO) **Q: Will 16.0V be too much?** A: Just need 14.3 to work good ## Customer Reviews ### ⭐⭐⭐⭐⭐ Clean power/sound Quality/Internal Fan *by T***8 on October 20, 2023* I started with a boss 400 watt 4 channel and I had really bad ground noise and engine noise.
