AMP4000D AMP4000D 4,000-Watt-Max Monoblock Class D Amp with Bass Remote

Sick amp for the $$! Works perfectly with correctly paired speakers 🔊 got two for two 15" gravity war zone green logo not red. It almost hurts.

Cool amplifier I'm thinking about getting another one for me brother birthday sound good I'm definitely happy

Stupid good deal. Bought it for like $85. Way too much power for my S series Alpine 12”. Have it on 35%-40% gain. I’d buy it again.

Good for the price

Very happy with my amplifier very quality sounding and was delivered fast

I bought this Blaupunkt AMP4000D thinking it was a reliable budget option, but it failed after just 18 months. What makes this worse is that I rarely use my car—I’ve only put 2,000 miles on it in the last two and a half years! So the amp was hardly used. ​After suddenly (after over a year), I started hearing a violent "thump/pop" every time I turned the car off, followed by a frequently dead battery, I took it to a professional installer to have it looked at. My first indication I made a mistake was when the installer said... Yeah, definitely do not but these cheap amps...they fail all the time. I was told the internal protection relay has failed and "stuck" which prevents the amplifier for muting during shutdown. But crucially, in addition to the loud POP I hear when turning the car off, I found out this sticking relay also keeps the internal power circuitry active, creating a severe parasitic battery drain that kills my battery if the car sits for more than a few days. Which is why I had to go and buy a portable jump starter recently! It’s incredibly disappointing for a product to fail this early with such light use. This amp is not only a battery-killer... It's a fire hazard! Stay away.

great amp you not gonna get 4000 WATTS OUT OF HER BUT YOU CAN GET AROUND 700 AT 2OHMS IM PUSHING JUST ONE CT SOUNDS BIO 15-D4 AND ITS MOVING IT TO THE POINT TO WHERE I MIGHT HAVE TO GET ANOTHER SO I DONT BLOW IT LMAO BUT HEY IF I BLOW IT COUNT IT AS A TROPHY GREAT AMP 50HZ LPF FOR THOES WONDERING IT DOES HAVE A HIGH PASS FILTER BUT FOR 1 CHANNEL YOUR MOST LIKLEY GONNA BE USING A SUB FOR IT MONO AUDIO SUCKS WITH SPEAKERS THIS A SUB ONLY AMP IM RUNNING THIS ALL IN MY HOUSE WITH 2 12V 50 AMP PSUS AND IT POUNDS SO YES YOU CAN RUN IT OFF OF STOCK ELECTRICAL IN YOUR CAR AND PUSH IT PORPERLEY

I purchased this for my son to use after he burnt up my Memphis Audio Monoblock Amp. It was a budget replacement that has outlasted the amp it replaced for a fraction of the cost. The included bass knob is a nice accessory to allow you to quickly adjust your levels when needed. The amp itself did run hot until we added a 12v fan under the center of the amp buy mounting the amp to the box with risers. This avoided thermal cutouts and has made the amp reliable and hard hitting. It is wired to 12" Hyanka subs and provide exceptional punch for the price.

De verdad el amplificador superó por mucho mis expectativas, no da la potencia RMS que dice, pero sin duda te da más de 600 watts RMS a 2 ohms, la potencia que genera sin duda te dejará muy satisfecho, lo recomiendo bastante.

Works incredibly well with my sub. Doesn't get too hot and didn't cut out at all throughout summer when I was absolutely punishing it with heavy bass Hardstyle.

Excellente qualiter

Best amplifier I have tried for the price I got the 4000d it’s very powerful as you can see it took the dust cap of my subwoofer and the terminals are nice and large the only fault I have with it is the kick does not sound that good I would give it 4.5 stars

Fonctionne tres biens bcoup de puissance,tres satisfait
