Planet AudioAC4000.1D Class D Monoblock Car Amplifier - 4000 High Output, 1 Ohm Stable, Low Level Inputs, Low Pass Crossover, Bass for Subwoofer

An amplifier's quality is defined by it's ability to efficiently and accurately reproduce it's input signal at a higher amplitude. Period. This amp is good.Without having metered the outputs under load, I couldn't tell you it's true RMS. What I can tell you is that this amp produces loads of clean power and is worth several times more than it costs. Any $500-$600 amp can deliver this kind of power, but likely wouldn't have as many usable features. I prefer audiophile grade gear for my own car, but this was a gift for my girlfriend and now her Civic dumps (1x RF P312D4 large slot-ported). I had to back the input sensitivity off considerably because her mids are still deck-powered (Eclipse) and she couldn't hear the lyrics. I didn't use the bass knob because it's ugly and the deck I gave her has adjustable sub control.The 4000 watt power rating is a joke, but it's the price that I'm laughing at. $125 doesn't buy much off the A-list.The multi-amplifier bridging capability is pretty rare, and much appreciated. The cable is even included. Unheard of.The power and speaker terminals accept forks, and are spaced plenty far apart. Whatever power cables you have WILL FIT.It's solid. The features are excellent. Buy two.MECP Master #CEA212201 (2013)

4k Watts for just over $100 bucks! Too good to be true you say, for something that isn't a piece of junk! I paired this with a Lanzar Optidrive 12'' 3000watt rms sub, I have 0 gauge wire for most of the way. The sub is in a ported 1.8cu enclosure and hits so hard that my Jeep hardtop flexes. I have been running this for a few weeks and the amp doesn't get hot, but then again I don't always want my neighbors to know I am home so I don't push it that hard. I have the sub wired in parallel and according to my meter it has a .8 ohm load, I know this amp is only rated at 1 ohm stable, but it hasn't gone into protection mode or heated up. I was worried about clipping, but I haven't had that checked yet, and the sub does not distort like you would think it would if the amp was underpowered, I have the gain practically down to 0 and it still hits good enough for me. If this amp lasts 2 or 3 years I would say it was well worth the $100.

I choose this 4000watt version mostly because it is 15"X10" & fits in the Nissan 350z glove compartment with about an inch and a half of space on each side, and about 6 inches in the rear of the amp. I am using the KnuKonceptz Kolossus OFC 4guage wire kit, and no capacitor. I am using a 120AMP ANL fuse supplied with the wiring kit, the amp itself has 3, 40amp fuses. I have yet to do the big three upgrade and I still get absolutely no dimming in my headlights, LED dash/undercar lights, or map lights!!! I used a Targus AWE45US HeatDefense gel laptop cooling pad for under the amp. It is made of crystals that when heated up turn into liquid, dissipating the heat. At the moment this amp does not even get warm to the touch, it literally stays at the cars interior temperature, even after hours of use. I have this amp pushing a 10" 4ohm, single voice coil, 300-1100watt Subwoofer in the 350z touring edition's stock Bose sub location. I used spray foam and dynamat to seal it into a 12"X12"X16" enclosure that only weighs about 3 pounds =). I have it turned up to 50% gain, and about 10% bass boost, the crossover is set as high as it goes (150hz) This amp slams so hard I barely half to turn my pioneer avhx2500bt head unit to half volume. I could still easily hear and could still faintly feel the punch from about 100 feet away. I plan on upgrading to a 10" pioneer premier series DVC (2 ohm) 3000watt sub.The RMS rating on this amp are very true to what this amp is pushing, if anyone tries to tell you otherwise, either they got a defect, they have a cheap CCA (copper clad aluminum) wiring kit, or they don't know how to wire an amp. A CCA wiring kit would have to be 3 times bigger than a OFC (oxygen free copper) kit, to push the same juice. So you would need a double 0 wire (-1/0) CCA wire to equal the 4 gauge OFC. The shorter the power cables the smaller it can be. The shorter the grounds the better.RMS Ratings are as followed:1500watts RMS at 4 ohms2000watts RMS at 2 ohms2800watts RMS at 1ohm / 4000watt peak.

So... A 4000 watt peak power amp for less than $140(price includes next day shipping). Just get it. I bought this amp because my 2 expensive Orion XTR15001's blew. I bought this as a quick replacement amp/backup so i wouldn't be without bass for two long weeks. I had to send my amps in for repairs. Man, this thing has power for sure. My setup is: 6 Kicker CVR 12's dual 4ohms, wired down to 1.5 ohms, a huge custom vented box with 3 chambers 2-2-2(subs facing up/not a wall), I was somehow able to connect 0 guage wires, two Optima batteries, and some other goodies. All in a 3rd Gen Exploder. Comparing this amp to other high brand amps like Kicker, Orion, JL, Rockford, etc... this thing is awesome for the price. This amp basically forces power to your subs. The bad part is that it lacks clarity. Something that I truly look for when buying an amp. I feel like i have 4 15's in an old school boxed Chevy without dyno... It's kind of sloppy. If your system doesn't normally hit the highs, this amp will force it out of them. Possibly pushing your subs to the edge. Or if your subs don't hit the lows, yeah you'll get it. Just be careful not to over do it. I'll end with this, the amp is capable of blowing all of my subs if I wanted it to. If you have some L7's, JL's, RE's, or even some Orion's, it'll BANG! If anything, just buy it for a spare like I did. Oh, connecting 0 guage was almost impossible. 4 guage is proper. If you do have 0 guage like i do, just strip some of the wiring and be sure none of the wires cross over! "Use electric tape." Enjoy this amp as much as I do! Don't mess with the sub-sonic gain if you don't need to. Peace my fellow bass heads!

Esta conectado a un 18" Audio Pipe 1400rms 2bobinas de 2ohms. 4 imanes.El amplificador sin ningún problema mueve a todo el subw. Se calienta muy poco .Lo que lo me gusta es que compre este y por muy pocos pesos el modelo anarchy 5000 D me quedaría por el momento para este proyecto y posteriormente para otro sub....Tendré que comprar el ac 5000 de todas las opciones aquí es la mejor y el sub también

Unbelievabley powerful.I honestly wasn't expecting that much outta it for the price but wow. It actually blew my two 12" 4ohm DVC 1500 watt pioneer premier subs in 30 seconds while tuning in the amp. So just be careful with this thing. For you curiosity I had wired in parallel to make them 1ohm to make the most out of the power....turns out I didn't need to.

Se calienta muy rápido

great amp! worth the money. mine did have a problem with turning off every half hour or so for no reason, but it really put the power down. make sure you have good wiring from your alternator to your battery to power this beast, it would dim my headlights on bass drops. i'm definitely going to buy another when i get the refund

El amplificador funciona a la perfección y el tiempo de entrega fue muy rápido
