Features
- Power - 4000 Watts Max x 1 @1-Ohm, 2000 Watts Max x 1 @2-Ohms

- 1 Ohm Stable - Able to continuously power loads of 1 Ohm without encountering difficulties such as overheating. Typically made to power up subwoofers that demand the heavier power load requirements to be able to perform the way they were made to
- Strapping Capable - You are able to strap two AR4000D amplifiers and double the power that is being sent to your subwoofer(s). You now have the ability to connect more subwoofers to take advantage of the extra power
- Variable Bass Boost - Bass Boost allows you to adjust the low bass within the boost range to just the way you like it
- Variable Subsonic Filter - To prevent your subwoofer(s) from bottoming out, the variable subsonic filter filters out frequencies below the subwoofer(s) specified low frequency limits and allows the driver to reach a maximum safe excursion
- Variable Low-Pass Crossover - Subwoofers reproduce sound based on a number of different low-range frequencies. You can set exact sound specifications for the bass frequency reproduction
- Specs - Dimensions: 14.3 x 6.5 x 2.8, Weight: 7.96 lbs.

UPDATE 11-10-16 After a week Still impressed, did a meter test and it was drawing 50 amps x 12v = 600 watts true rms @ full volume. So I Upgraded my wire and new better battery terminals and 100a fuse holder. Did another meter test and i got 100 amps x 12v = 1200 watts true rms... it blew the fuse holder. So I ordered a better fuse holder with 150a fuse.. will do another update when installed After reading almost all the reviews for this amp I decided to just go for it! Glad I did! I needed an amp the can push (1) 15" Orion HCCA dual 2ohm wired to 1.13ohms exactly. That being said, I got my amp today and installed it my self. I was really nervous at first thinking this amp would not be able to push the sub hard enough and thinking the amp might blow a fuse or something of that matter. Turn it on and I was Amazed by the amount of power it was feeding my Orion. Put it this way, i couldn't even go past 1/4 turn on my bass knob and the head unit past 1/3! The sub was flexing about 3 inches, my hair and beard was vibrating and my truck felt like it was gonna fall apart... I mean the doors were flexing so hard it looked like it wanted to open. And my windows looked like they wanted to chatter... amp settings were set all to minimum except the gain wich I was controlling with my knob. Honestly I'm afraid and excited and nervous to turn it half way thinking the air bags will set off or windows chattering... I drive a 2009 2 door Ranger , with stock head unit and I removed my passenger side seat to e able to fit my 15 inch sub.. it takes up the whole space.. I will update once I crank it up more and run it for a bout 45 min... Extremely happy with this amp and for the price you can't beat it! Hope this review helps.. if it can hammer my competition 15" Orion HCCA it definitely can hammer any other sub out there with ease.. might even blow your sub if your not careful ... As for the negative reviews, well you prob don't know what your doing, not hooked up at the correct ohms the amp requires will definitely blow your amp! Update-1 Just noticed it cracked my front windshield !!

So a year and a half ago, I was gifted 2 infinity reference series 12 inch subs from my brother. it was clear that I needed a large amp to power it. I had an mtx 750, and it didn't work as well as I expected it. but then I saw a 2000 watt boss for 75 bucks. I decided to go for it. it has been running at full power since I purchased it. I bought 2 twelve inch Rockford fosgate punch 12s and found out that they little 2000 watt amp would not push all 4. so I brought out the big guns. I ordered 2 ar4000 monoblock amps, 1/0 pure oxygen free copper, going to a .5 farad cap and a 2 farad cap. split into 2 lengths of 4 gauge jl audio pure copper. I set it up put the bass level to full. big mistake. I cracked my windshield, edge to edge, on the passenger side of my car. my mirror vibrated all the way down until it was looking at my dash. my check engine light came on and made my car misfire for a few seconds. and my neighbors car alarm went off and in turn made them call the police on me. I'm seriously impressed with they whole armor line of amps from boss. I might just be purchasing another! you will need a spare battery to run these at their peak, because they will kill your battery on extended trips with the level all the way up. Edit: now have 6 subs, 4 alpine bassline 12' 1 infinity reference, and 1 12 inch sony xplode 1200 watt, with a total max load of 6542 watts. I had a failure in one of the other infinity subs so I replaced it.pushes all of them very well. my best friend left cookies on all my subs while I was working on them, and when I went to turn it on, shot cookie bits all over my car. 2nd edit. I am now running 2 soundqubed hdc3.18 subs in a 12 cube box 35z at 0.5 ohm. It pushed them hard but clips if my voltage goes uder 13.5. It also gets very ho.

Very satisfied with the product. It is exaclty as described in the description. Very solid amp, and the quality is amazing. Easy install as well; with some common sense and little wiring knowledge i was easily able to hook up the amp properly on my first try. The biggest struggle was having to look up how to take apart the dash on my and trying to find a proper place to put the ground IN my truck! Haha. But all in all, its a very solid product and its worth every penny. Highly recommended to anyone who is looking for a good amp to support some badass subs! I also bought the Boss Audio Kit10 4 Gauge wiring kit, and it had everything I needed, highly reccomended as well!!

Due to the weather here in Texas it's been in my closet since Feb 21. When I finally attempted to install, it didn't work. Cool Ithought, I will just return it for another considering I order alot of electronics (I have 12 cars, so I get stuff often)..........NOPE. Found out it is unreturnable. Love Boss and the shipper but won't order from them nor AMAZON again.

Well after my 2000 watt crunch amp fried after 10 years [but this amp never flexed unless put at the max on a A/B amp without heat issues and my back seat folded down for air...lol] ...but i think my ground was the culprit. Always attach to body near the amp, previous in the engine body mount...can be a source of resistance in the line for some reason. Terminal melted on Crunch amp... Now back to this BOSS HOGG amp; ummm its barely turned up on my two 12 inch Infinity @ 2x600 RMS subs. Now this amp flex on low continuous bass notes without distortion or effort even on low power. Never had that before; does not have heat issues either..but its turned down ...lol...so i dont think it will unless its one of these hundred degree days in Houston. Make sure you run your engine; unless you have it turned down some serious power in this amp. This amp was #1 rated and it is. LPF & HPF for any newbies has to be changed.
