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 Peak Power Output
The total peak power output is measured as the wattage per channel multiplied by the number of channels, and is calculated at the lowest level of operating impedance.

It is measured during a brief musical burst, such as a sudden drum accent. Some manufacturers display peak power ratings on the face of their products to increase the appeal.

The RMS power rating is more accurate, and we recommend using it for product comparison.

2400 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.
0.1%
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.

30 - 250 Hz
Subsonic Filter
Allows you to block (filter) ultra-low frequencies that your subs cannot reproduce.
15 - 35 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.
<0.1 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 - 10 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
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.

No
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.
Amp Bluetooth Connectivity
This feature will tell you if the amplifier has the capability to connect to a Bluetooth device.

Very satisfied!

November 3, 2014

Paired amp with two 1200w subs in a custom box in trunk of my 2006 mustang convertible and installed amp volume controller on driver's side of interior center console. Subs perform great and let me hear and feel the bass even with the top down. I can easily adjust the amp volume while driving and listening. Amp performs very well, looks good - lighted blue letters on front - and the written instructions on installing and adjusting it were very well done. Very satisfied customer!

I would definitely recommend this amplifier. I have it pushing two 12 re Audio sxx subwoofers in a sealed box. And this thing bangs. The box seems like its coming apart. I'm running amp on a 1 ohm load with no extra battery. I'm running true 0/1 gauge wire on both positive and negative. I have this set up in a 2003 Ford mustang gt and its loud actually see the back window doors just everything's flexing. I have amp turn up to about 35 %. Bass boost barely up and bass on radio on -6 .this amp is great like I said I would recommend this amplifier to anybody. Hifonics amplifier for now on

April 28, 2014

It really doesn't state the actual rms it only says its rated at 2400 watts at 1ohm. However it does sound great, i have two 12 inch Boss Phantoms hooked up at 1ohm in a sealed enclosure. The subs are rated 1150 watts each so that makes them a perfect match. Regardless if actually puts out that power i am completely satisfied and my sound sound system is extremely loud for the price.

April 22, 2014

I actually work at a local car audio shop that does not sell Hifonics products but have seen them in customers vehicles and was impressed with what I saw and heard. I had a goal in mind to put a "budget system" together in my 98' Tahoe with some RF P315D4's I had from a previous build. This amp is bridged down to the 1ohm load and does NOT get hot. Has been bangin' my 15's since I got the amp. Hits so hard it rattles your teeth no joke. I have demo d' it to some customers that have been looking for a good power alternative thats not too expensive for some really good/clean power. I will buy more Hifonics products from you.

This amp is killer! Puts out very close to what they say it does. The brushed aluminum looks awesome, as well as the blue LEDs around the name. Puts out a very nice clean bass, and will slam your subs all day without getting hot (does get warm, but not hot) The only reason I gave it a 4 on durability is because of the plastic mounting tabs, but if you're careful this will not be an issue. You cannot and will not find a better value for an amp of this quality. Highly recommended.

May 12, 2014

This amp is great. Puts out 2380 watts rms read with a dmm at 60htz. I have this amp pushing 2 alpine 12in type R's and I only have this amp at like 40% it straight slams. So glad I bought this amp. Would recommend to anyone looking for a great 1 ohm stable amp that puts out lots of power. The only this I have to complain about is that the feet used for mounting are plastic while the rest of the amp is pure aluminum. They brake very easy. But other then that no complaints at all.

is it stable 1ohm?
tolzi on Aug 24, 2014
Best Answer: Hello Johmz,

A 1ohm rating is given, which implies it is stable at that impedance. The Features and Spec tab confirms its lowest impedance of 1ohm, in addition to the information found on the manufacture's site. Therefore, Yes.

I have 2 kicker cvr's 12 they are both dual 4 ohms voice coils how should I wire them so they work with this amp?
A shopper on Aug 11, 2014
Best Answer: one way you can do it is wire them speakers at 2ohm each positive positive negative negative right to the Amp but that will be a lot of power for those speakers at 1ohm you might be better off wireless speakers at 8ohm each take the negative from one. Coil hooked up to the positive from the other voice coil take the other negative and positive to the amp do both speakers like that that will bring you down to. 4ohm get less power from the amp but you don't have to worry about your speakers blowing

Do you still need to set the Level (Gain) on the amp?, Or does the wired remote take control of it.?
A shopper on Aug 2, 2014
Best Answer: Yes you still need to set your desired gain on the amp. I put my wired remote at mid level when I set it. This way you can turn it down lower or higher with the wired gain control

Anyone else have the problem were you bought the belva 0/1 gauge amp kit and amp and after being installed played good for a while but amp burned after ignition was shut off after some time anyone ?????
A shopper on Aug 6, 2014
Best Answer: Have not had that problem but it is the connection of the amp turn on wire. Where ever you have it hooked to doesn't cut off immediately. One way to check it is as soon as you cut the car off unhook the amp turn on wire from the amp and see if the light goes off.
