Power Specifications - Subwoofer Channel

Peak Power @ 4 ohm
This form of power rating refers to the maximum amount of power an electronic device can handle or output in an instant without damage occurring. Often times this maximum is achieved during a brief musical burst, such as a drum accent, or low bass hit.

Some manufacturers display peak power ratings on the face of their products to increase the appeal to consumers. The RMS power rating is more accurate, and we recommend using it for product comparison. However, some manufacture's do not provide an RMS figure and therefore one cannot be advertised.

Amplifier Specifications

Amplifier Series
This designates the series of the amplifier. Many amps are available in a litany of different wattage and channel configurations, but maintain consistent features throughout the product line.
Zeus (Hifonics)
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.

D
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.

1800 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.
4 AWG
Minimum Impedance Unbridged
The lowest impedance the amplifier will handle when it is not bridged.
1 ohms
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.
0.10%
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.
No
Preamp Outputs
Many amplifiers are equipped with RCA preamp outputs which pass the original music signal from the source to additional amplifiers. This is known as daisy chaining because the source connects to the first amp, and the first amp connects to the second amp, etc. The advantage to daisy chaining is you only need one 2-channel RCA cable to transfer the signal from the head-unit to the amplifier, and then one additional cable for each amp being daisy chained.
1 pair
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.

40 - 300 Hz
Subsonic Filter
Allows you to block (filter) ultra-low frequencies that your subs cannot reproduce.
10 - 40 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.
95 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 - 12 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.
Yes
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).
No
Fuse Rating
The amperage and the number of fuse(s) an amp requires.
60A x 2 
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.

Great Price for the performance

June 28, 2015

I purchased this amplifier because I have heard a lot of positive reviews of hifonics amps saying they never let you down, so I decided to give them a shot. From the get go as soon as I got the box the whole image was very intimidating with the box saying "power from the gods" and I was very pleased with the overall design and appearance of the amp itself. The bass knob has a light-up ring which is eye candy at night, and if it goes into shut off mode the ring turns red. I am using it for my 15" Kicker l7 in a 5 cubic feet box and it pushes it HARD. I am using it in my 1999 v6 mustang and I finally got it to flex the windshield a bit and it hits lows like a champ. The only downside I have for this amp is that it does not like the heat and will overheat if there is no proper ventilation.

My husband is completely satisfied. He was so excited when he received his order. He was so happy that he was like a child in a candy store. He couldn't ripped the box faster. He said it was easy to install and overall love the performance that he wanted. I literally could hear him from the next block. He said he likes it loud and obnoxious.

what and how many fuses are there? it shows two 60 amp fuses but specs say two 70's??
mike w on Jun 19, 2016
Best Answer: t has 2 60 amp fuses and I highly suggest this amp as well it's a beast it can run for HOURS without even getting remotely hot I run mine in my garage while im working and when my battery starts to die I throw my charger on it.....I've ran it for 10 hours straight before with my massive audio toro 124....also highly suggested brand since it's not as well known it hits more of the lower frequency notes

Would this amp work fine with my punch p3's model number P312D2 dual 2 ohm, 500 watts rms, 1000 watts peak?
Christopher K on Dec 22, 2015
Best Answer: Hi Christopher,

Like Benjamin said, you would have to be VERY careful - and to be fair, we don't recommend it. At "1800w Peak" this amplifier is likely doing anywhere between ~700-1200w RMS at 1ohm , which is far more than your driver is asking for.

Instead, we recommend the Hifonics BRX1516.1D, wired up to 4ohms.

The picture shows two pair of rca inputs and two channels... i thought it was a monoblock?
Travis N on Jul 9, 2015
Best Answer: Hello Travis,

Not necessarily. Take a closer look.

http://www.sonicelectronix.com/pictures_new.php?id=94889&picture_id=2369954

That is ONE set of "Inputs" and the other set of RCAs is an "Output" . Moreover, the two outputs (NOT CHANNELS!!) on the speaker output side are to make installation of multiple drivers easier. Obviously if you are only going to use ONE subwoofer, then you will only use ONE output =] . This monoblock is still a monoblock and is simply - although clearly a bit confusingly - set up as a 'pro monoblock' . Here are a few other examples of 'pro monoblocks' that are set up this way:

Best Answer: This amp will put out 1800w RMS @1ohm. The enclosure you have here is internally wired at 1ohm for 800 watts RMS, so if you use this amp, you will be overpowering your subs by ~1000 watts. Not a good idea at all, as you will blow the subs. Find an amp that will do 800w @1ohm. You should always go by the RMS rating not the max, as max power handling only happens for a fraction of a second, and not very often. Hope this helped! Cheers.
