BOSS AUDIO AR4000D Armor 4000-Watt Monoblock, Class D 1-8 Ohm Stable Monoblock Amplifier with Remote Subwoofer Level Control by BOSS Audio

Wouldn’t buy this again

Bought this thing for under a hundred bucks in January 2017 I believe? Lasted me up until probably 2022 or 2023 I think, which wasn't bad for $125 at the time. And I beat on this thing - loud settings, hot trunk, no ventilation or anything whatsoever. When it finally died, I emailed Boss and they had me send it in and gave me a free replacement - after like 5 years! Great product support. I didn't expect them to do that, but the fact they did it anyways was fantastic customer support. I've since outgrown the need for a dedicated subwoofer in the trunk, but last time I checked it still works. Absolutely great product. I'm also not sure what car amplifiers go for these days from reputable brands, but I'm sure it's much higher than $180. Highly recommend this!

Super

Really good product for the price, I would recommend these amps to anyone looking for good quality, good solid power, and great performance.

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 !!
