For $50, this AMP works flawlessly. It has never turned off from being too hot and I am an Uber EATS driver, so my car is on ALL day. The best part about this AMP, is that is has a Line Out Converter / High Output adapter installed inside it and it comes with wires. My LOC didn't arrive when the AMP did so I was pretty mad, then realized that it had that adapter and was immediately excited again. VERY easy to hook up and use. I recommend this for anybody New to bass systems and looking to install a simple 12". I've got a 1000w 12" Kenwood Subwoofer installed to it. Beats HARD. You won't be dissapointed. HERE'S SPECIFIC INSTRUCTIONS ON INSTALLING YOUR SUB TO STOCK HEAD UNT YOURSELF. - Subwoofer should be in enclosed box. - Amplifier is best screwed to the subwoofer box - Take the Power wire, cut it as needed, and wire it to the BATTERY input on the AMP, then run it to your car battry Positive Terminal. ( I wrapped the wire around it and stuck the Cars wire harNess over it and tightened it ) - Ground wire goes to the GRND input on the AMP then goes to either a bolt in your trunk ( which shouldn't be painted ) or If you have a fuse box in the trunk with a ground wire, you can use that bolt as well. - Blue power wire. That goes to the REM / Remote input on your AMP and runs either to the power wire in your head unit, or a fuse that turns off when car is off. ( I used my ignition fuse. I Wrapped a wire around it barely, so I could get it back into the fuse slot ) Now that your AMP will have power when the car is turned on or in the accessory mode, we can now wire the speakers. Easiest part, just nobody ever describes it good. -Your subwoofer has two inputs on the box and the subwoofer should be wired inside the box as well. POSITIVE TO POSITIVE, NEGATIVE TO NEGATIVE. - Your amp has a positive and negative input. Use the speaker wire you have and wire it to the subwoofer box, from the AMP. Positive to Positive, Negative to Negative. Positive is often times a silver wire, as Negative will be Copper. OFTEN, not for all speaker wire. NOW, the LOC if your bought one, or I'f your using an AMP like this, which came with an adapter installed in the AMP already. - The LOC / Adapter wires both are the same. They have 5 wires and some LOCs only have 4 wires. With 5 wires, there is a ground wire which I used a piece of Negative speaker wire to make it longer, then ran that to where I had the AMPs ground wire. - Locate your rear speakers and figure out which is the Positive connector and which is the Negative. The Wires on the LOC or Adapter wires will be like this if your looking at it POS. NEG. GROUND. NEG. POS. OR if you only have 4 wires without the ground, ignore the ground. When the adapter wires are plugged to the AMP, you'll see which side is Left and Right. So from there, simply tap those wires into the Left and Right rear speaker. You can take the plug off the speaker wrap it around snug, and slide the plug back on. That's what I did. Just make sure POSITIVE is POSITIVE and NEGATIVE is NEGATIVE. The Wires on the LOC are very short and so are the wires on the Adapter wires foe the AMP if you don't have the LOC. If you are using an LOC, once those wires are tapped to your rear speakers, plug in the RCA and match the colors up correctly. Make sure whatever wires you cut, are properly wrapped In electrical tape or if the shrink wrap, whatever you use. Now, turn your Car on and your AMP is ready to go, and your Bass system should now be bumping. Adjust the GAIN and volume on yur amp according to your taste. If your AMP does NOT come on, it's because your blue power wire isn't installed correctly. Best way to test your AMP is find a normal fuse to something that's always on, like a cig ligter. Use different fuses until you get it to turn on then property identify your ignition fuse that way the AMP cuts off when yu turn the key off. Your welcome. Review: Good amp! - This is a solid amp as long as you don't expect 1500 watts. It's a more realistic 600W max with an RMS of around 200. The fuse is 30 amp, which at 14 volts equates to 420 watts. It's at most 60% efficient, so that's 252W output. And since that's probably still too high, let's call it 200 watts RMS. It sounds good and doesn't distort unless you really crank it up. Even at 200W it shakes my mirrors and rattles the trim pieces. Punches hard and sounds good with an Infinity 1262 wired at 2 ohms in a Scosche truck box. Pros: Sounds good Small, and lightweight Has high level inputs Cons: It gets hot, but I haven't had it shut down on me yet Not anywhere near claimed output So overall, I'm impressed with this amp, at least for the price. It's a solid amp for a good price. If you're looking to add some low-end to your system, this is a good way to do it. ## Features - Power - 4000 Watts Max x 1 @1-Ohm, 2000 Watts Max x 1 @2-Ohms - Class D - Power loss is significantly reduced making the amplifier highly efficient. Excess energy is stored until it’s needed instead of being converted into heat. Reduction in size/weight, reduced power waste, smaller heat sink, compact circuitry - 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004RS9UTI | | Best Sellers Rank | #72,191 in Electronics ( See Top 100 in Electronics ) #169 in Car Mono Amplifiers | | Brand Name | BOSS Audio Systems | | Customer Reviews | 4.2 4.2 out of 5 stars (3,931) | | Global Trade Identification Number | 00791489116404 | | Included Components | Remote subwoofer level control | | Item Dimensions | 14.3 x 6.5 x 2.8 inches | | Item Type Name | BOSS Audio Systems AR4000D Class D Car Amplifier - 4000 Watts, 1 Ohm Stable, Digital, Monoblock, Mosfet Power Supply, Great for Car Subwoofers | | Item Weight | 8 Pounds | | Manufacturer | BOSS AUDIO | | Model | AR4000D | | Mounting Type | Car Mount | | Number of Channels | 1 | | Output Power | 4000 Watts | | Specification Met | FCC | | UPC | 803983124578 807032956639 791489116404 | | Voltage | 10 Volts | | Warranty Description | 6 Year Platinum Online Dealer Warranty valid only on products Sold / Shipped by Amazon.com.

From the super expensive, big name stuff, to less expensive systems. I am surprised by the BOSS AR2000M. For a supposedly, "Cheap grade & China made" amp, it performs exceptionally well. (Lets face it, most are made in China,Taiwan, etc !!!). But paired with 2 PYLE 15" 1500 watt, single voice coil subs, wired parallel for 2 ohm imp. (max. power) and mounted in a quality, quad-vented solobaric box, it Freakin Bumps!!!. Excellent bass response, no distortion, and great overall sound quality. It has good features, quality contacts, & rugged construction packed in a small, managable sized unit. Honestly, I have no complaints & for the price and quality, I believe I made a great choice. Sounds better than most of the "Big Name" amps that I paid way too much $ for, because thats what i paid for, the "Name" & a fancy symbol on the housing!! But I will definitely recommend & purchase more BOSS products without a doubt !!
