Power Specifications - Subwoofer Channel

RMS Power @ 4 ohms
The RMS power rating is the measure of continuous power that an amplifier can output, or a speaker can handle. It is the most accurate depiction of real, continuous power that the industry has so far. If the final impedance of your speaker(s) or subwoofer(s) equals 4 ohms, this is how much power this amplifier will supply at that ohm level. The higher the RMS wattage, the more clean and loud your music will sound. The 5th channel on these particular amplifiers are usually dedicated for driving subwoofers.
1020 watts x 1 channels
RMS Power @ 2 ohms
The RMS power rating is the measure of continuous power that an amplifier can output, or a speaker can handle. It is the most accurate depiction of real, continuous power that the industry has so far. If the final impedance of your speaker(s) or subwoofer(s) equals 2 ohms, this is how much power this amplifier will supply at that ohm level. The higher the RMS wattage, the more clean and loud your music will sound. The 5th channel on these particular amplifiers are usually dedicated for driving subwoofers.

Amplifier Specifications

Amplifier Class

An amplifier increases the power of the signal being fed to it by taking energy from its power supply and matching the signal but increasing its amplitude. Amplifiers use many different methods for converting these electrical signals and have been categorized into classes.

Class A/B: Greater than 50% of the input signal is amplified while the other percentage is “off”. These amplifiers have a small amount of current flowing through the output transistors all the time which almost eliminates crossover distortion. Class A/B has great sound quality but is not as efficient as class D. These amps are most commonly used to drive speakers.

Class D: Also known as switching amplifiers, class D amps have output transistors that are completely turned “on” or “off”. This means that when the transistors are on, there is almost no voltage across them but when they are off there is significant voltage but no current flowing through it which makes these amplifiers very efficient at the cost of sound quality. These amps are most commonly used to drive subwoofers.

Other Classes: You may see classes such as GH, bD, X, FD, etc. by some manufactures. These amplifiers tend to be either class A/B, D or a hybrid of the two but with improvements to their designs that can make them more efficient or offer better sound quality.

Number of Channels
Each channel on an amplifier will power one speaker using a positive and negative cable. There are various types of amplifiers, each designed to power a certain number of speakers. Monoblock amplifiers, also known as single channel, are designed to power one or more subwoofers. These amplifiers often have very high power ratings. On the other hand, multi-channel amplifiers power multiple speakers, usually at lower power ratings. 2-Channel and 4-Channel amplifiers can power car speakers or low powered subwoofers. Occasionally you might see a 5 or 6-channel amplifier that can power speakers and subwoofers at the same time. The most common setup is a monoblock amp to run subwoofers and a 4-channel amp to run door speakers. Check out our Knowledge Base for more information.
1 - Mono
Total RMS Power Output
Total RMS power is measured by multiplying RMS power per channel by the number of channels, and is calculated at the lowest level of operating impedance.

RMS power is the amount of continuous power, measured in watts, that an amplifier produces is called RMS power. The higher the RMS figure, the louder and cleaner your music sounds.

The RMS output figure is much more accurate than the peak rating when comparing products.

3000 watts
Maximum Input Gauge Size
This is the largest gauge wire that will fit into the power and ground terminals of this device. The lower the gauge number, the thicker the wire is. For example, a 4 gauge wire is thicker than an 8 gauge wire and thus has higher current carrying capacity. Always do your best to get this size wire to reduce the risk of damage to your components.
1/0 AWG
Minimum Impedance Unbridged
The lowest impedance the amplifier will handle when it is not bridged.
1 ohms
Minimum Impedance Bridged
The lowest impedance the amplifier will handle when it is bridged.
Not Bridgeable
THD at Rated RMS Power
The amount of change in harmonic content of the signal as it is amplified. A lower figure indicates less change and a more accurate amp. THD below 0.10% is inaudible.
Speaker Level Inputs
Speaker level inputs are commonly referred to as high-level inputs and vice versa. This input type allows you to get your audio signal directly from the speaker wire in your vehicle, instead of using RCA cables. The advantage of this is factory integration, as most stock radios do not have RCA outputs to run amplifiers.
Built-in Crossover

A crossover is a type of filtering system that permits only certain frequencies to play. A Low-Pass (LP) crossover allows only frequencies below its setting to get through which is good in the case of some subwoofers. A High-Pass(HP) filter allows frequencies above its setting to pass through, this is normally used on speakers.

When a crossover is set to FULL it means no filtering is added and the full frequency spectrum is allowed through the amplifier. Filtering is important because feeding a speaker frequencies it cannot reproduce effectively creates distortion.

Low-pass (LP)
Low-Pass Crossover Frequency
The low-pass crossover frequency is typically used for subwoofers. It can be a fixed crossover point or a variable crossover range. A variable low-pass crossover allows you to select a specific crossover point which allows frequencies below the set crossover point to pass, while making frequencies above the set point gently or harshly roll-off, depending on the steepness of the slope.

The steepness of the roll-off slope is measured in dB/octave and refers to the rate of attenuation (lowering of volume) outside their pass bands.

30 - 250 Hz
Subsonic Filter
Allows you to block (filter) ultra-low frequencies that your subs cannot reproduce.
10 - 30 Hz
Signal-to-Noise Ratio
This spec compares the strength of the signal to the level of background noise. A higher value indicates less background noise.
90 dB
Bass Boost
The objective of the bass boost is to get more kick out of your subwoofer. It is a circuit that emphasizes the lower frequencies at a given point. The bass boost should always be set first before setting the gain. This feature is known for destroying subwoofers and is commonly used incorrectly, so be cautious.
0 - 9 dB
Bass/Gain Remote
If the amp comes with a bass/gain remote you will be able to control the level of your bass from your dashboard. Typically bass remotes also include a 16-20 ft. wire for installation.
Fan Cooled
A great feature to have if an amp generates a large amount of heat. Cooling fans can help regulate the temperature to prevent the amp from overheating (burning).
Fuse Rating
The amperage and the number of fuse(s) an amp requires.
300A External Fuse Required
Some amplifiers can be "strapped" together in order to increase the output of a single audio channel. These amplifiers feature RCA preamp outputs, allowing you to pass the signal directly from one amp to the other to ensure consistency.
CEA-2006 Compliant
Amplifiers that have been tested to meet specific standards. When a car amplifier meets these standards, you can be sure that it will be able to produce the amount of power specified by the official CEA-2006 rating. Usually, these rating consist of the following items:
  • RMS Power
  • Signal-to-Noise Ratio

This rating applies to both external car amplifiers, as well as the amplifiers inside of in-dash stereos.

Sonic Certified Amplifier
Sonic Certified amplifiers have been tested by the experts at Sonic Electronix to meet or exceed the wattage ratings provided by the manufacturer. If this is marked as Yes, then you can trust the wattage ratings. If marked as No, then we have tested the amplifier and it did not meet the advertised wattage ratings. If marked as Not Tested, then the Sonic Electronix experts have not yet been able to test the amp.

Great amp!

April 29, 2014

I have this amplifier powering two NVX VCW 124's in a custom ported box. It makes big power, so be sure you have the big 3, 10 farad cap or H/O alternator to get the best benefits. It produces great sound quality at decent volume levels and has yet to get hot. It's relatively small footprint is impressive for the power it makes. PROS: Great quality build, great quality sound, decent price. I like the simple, sleek look of the amp. NVX doesn't use flashy lights and gimmicks, just a grown up, clean, professional look and performance. CONS: Bassknob. The bass adjustment knob on this seems to be quality... at least on the outside. The casing is solid metal and the knob has a good resistance as you turn it. However, the LED on it was WAY too bright... when it was working. About 5 minutes after hooking it up, the LED stopped working. (Which was fine with me because it was INTENSELY bright. And that was in daylight!) From 0-35%, the knob adjusts the bass level a bit too aggressively. From 35% on up, it seems to do little to no adjustment. I still make use of the bass knob as I listen to a huge variety of music. I would certainly like to see an improvement in this area.
However, this does not take away from the fact that this amp beats smooth and steady. I would absolutely recommend it to anyone serious about their bass.

There are no other words besides awesome! I've had this for over a month powering my Orion HCCA Competition Sub and it keep feeding it all the power the sub can take.The Amp case is solidly build which helps with durability toughness. The Angle terminal end give it a professional look but can be a pain at times with 1/0 gauge wiring running to it.
The only problem I have is the remote LED is too bright. It's blinding trying to drive at night and even during the day at times.
This amp is by far one of the best amps I have ever purchased.

Powerful and Clean sound ! Quailty korean built amp

July 11, 2014

ive got the XPLD3k running 6 600RMS 12'' subwoofers and it pushes them to the very max ! it is very efficient compared to the other 3k's i have owned in the past , i do suggest running a ohio generator alternator and a couple of good agm batteries . the amp stays very cool due to its very big heavy heat sink ,no fans but they are not needed and there is some small vents in the side plates and no other vent holes which is nice so your amp does not get much dust or anything inside it . the angled inputs are kind of a pain but do really make the install look nice and clean with minimum wires showing , overall its a great amp and the cost on it is amazing ! id highly recommend it to anyone , also i dont use the bass knob at all ''never took it out of the box'' i instead use the NVX XBRC which adjusts your rca's going into the amp rather than adding bass boost and distortion

Better then hifonics

August 31, 2014

I bought from sonic electronix because I'm buying from canada and there's very few sites that offer warranty over the border.
I DID previously purchase a Hifonics amp from a different website that ended up catching fire and almost burning my Infiniti to the ground, just to find out that they wouldn't cover the warranty because I'm in canada.
I can tell you sonic DOES offer warranty to canada, and because of this, I've been buying (and will continue to buy) my car audio from sonic electronix. I was after a powerful amp, and this amp came recommended from Wes (at sonic) and he gave me an amazing deal on that and on the shipping. I am completely satisfied, I'm only running the amp at 4 ohms at the moment and it's a crazy amount of power, I can imagine when I get it to 1 ohm! Thank you sonic electronix!

Will this be a good match?
3 15'' NVX VCW Dual 2 ohm subs and this amp wired to 1.33 ohms?
Will there be enough wattage to go around?
(Im going off the wiring guide for 3 dual 2 ohm subwoofers)
FatMat916 on Jan 29, 2015
Best Answer: Hello Matthew,

This is all in Theory and Trusting the figures provided (which is a Very Safe thing to do): Three VCW152 wired in series/parallel to a 1.334 load will work well on the XPLD3K . The figures we are basing this on are the Dynamic Results established by our Bench Test . In theory, based on the figures that the amp is doing @1ohm & @2ohms, the amplifier is likely putting out ~3000-3500w RMS @1.334ohms. It is impossible to establish this with certainty, because there are far too many variables involved. However, assuming you are going to use proper wiring, a proper signal, and a proper install, then it is safe to conclude that the setup will work very well.

I am a hifonic fan, but lately they have been coming up short on power.i would like to try this nvx 3000 rms, any good things about this amp?
Derwin R on Jan 17, 2015
Best Answer: Hello Derwin,

I've gone ahead and submitted your question, so hopefully a few customers will chime in shortly. As far as our input goes, We've gotten great feedback from those that have chosen the amp. From what we have seen, it runs far more efficiently than the amplifiers offered by Hifonics, but that is a bit implied, given the price tag. As you can see from our Dyno results, the amp makes well above rated figures, so they definitely are doing things right. Nevertheless, I suggest looking up reviews from others (google/youtube/etc..) so you aren't hearing feedback Just from us.

Will a 270 amp alternator and a 2400 watt kinetic battery run this amp ?
Derwin R on Dec 25, 2014
Best Answer: Hello Derwin,

That is a very solid setup for this amp to run well. I assume you are referring to the Kinetik HC2400 as your battery, of which will do a fairly solid job of keeping up with the amp. Assuming you wish to run the amp at 1ohm, then an Auxiliary Battery like the XS POWER D1200 is preferred; This is assuming the HC2400 is being used as a Primary.
Also, don't forget to make sure that you are running 0 Gauge OFC Wiring as your Main Power/Ground and Big 3 Upgrade!
