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 amp for the price. I was skeptical at first reading reviews. Realistically getting about 12-1300 RMS at 1 ohm. Haven't had any problem with over heating or protect mode and I run it hard. Make sure you use proper ofc wiring and terminals. I've given 4 stars only because I haven't had it very long

Worth the money. Makes 3- 12" 1200 watt subs pound.

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.

Speedy delivery looks awesome sure it will be great for my needs thank you

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

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
