BOSS Audio Systems AR4000D Monoblock Amplifier - 4000 Watt Amp, Class D Car Audio Amp, 1 Ohm Stable, Mosfet Power Supply

Boss is a mid-range mid-grade product. Through out the years, I have always somehow found myself purchasing Boss products. For the money, you cannot beat the product. If installed properly, It can give you years of service without problems. I installed this little monster on 2 Boss 12"s, Which my cousin laughed at me for being "cheap" because he has always had fosgate and infinity products. But, his smile soon turned into a frown when I pulled up to his house and my "CHEAP" Boss speakers kicking so hard they were knocking pictures and Clocks off his walls. Which boils down to this- Boss is a solid product, and has been around a long time. Don't listen to people who don't know anything about car audio. Do your math- and figure out how much you want to spend- And install BOSS- YOU WILL NOT BE DISAPPOINTED!

this is the best amp your going to find for 100 bucks I got 2 of them 1 for each speaker that are wired at 1 ohm a piece and it hits hard your never going to find a better 1 ohm stable amp for the price

Great amp!! Only complaints are it gets warm pretty quickly and two is that it takes small wire I got 0/zero gauge and that was to big but I made it work! Other than that love it it makes my pioneer 12 in. Champion series bump!

This amp pumps out the watts just waitin for my 15'' phantoms now blew my old woofers. Big bang for the buck

Great sounding amp. Goes great with the boss 10" sub that I have for it. Plenty of power!

good amp for the price range

This amp is more than I expected. It makes my 15in pound i was surprised. and the little base knob is nice to have at your fingertips

I never thought that an amp this cheap could perform like it's doing. I wanted to add some booming sound to my auto but didn't want to spend to much money on it. Really, just looking for a little louder than what stock sounds like. I started to shop around for an amp, speakers, and subwoofers. Well one of My friends had 12 in subwoofers and he sold them to me for cheap. So I found this Boss amplifier, that makes those subwoofers bump really loud. The Boss is taking care of business for me and it was delivered really quick and it works perfect. Thanks Walmart for selling good stuff at a low low price.

Works as intended not true wattage on box

it works like its suppose to! have had it for a while now and no issues so im happy and it was easy to install
