Hifonics Car Audio Store Defying Limitation

Extremely high output is not something to be toyed with. The call for extremely high power has been answered by the Hifonics-XX Goliath. A whopping 5000W RMS is output by this amplifier, making it one of the most high output amplifiers available on the market. Only the most capable subwoofers on the market are ready for the power this amplifier can output.

Think your subwoofer is able to handle the Hifonics XX-Goliath’s capabilities? The options don’t stop there. Select Generation XX amplifiers can link together so the audio channels can be controlled from crossovers. This allows you to bridge two amplifiers, towards one subwoofer – resulting in doubled power!

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.
1800 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.
3200 watts x 1 channels
RMS Power @ 1 ohm
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 1 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.
5,000 watts x 1 channels
Peak Power Output
This form of power rating refers to the maximum amount of power an electronic device can handle or output in an instant without damage. 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. This is the peak power output for the amplifier's 5th channel.

Amplifier Specifications

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
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
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.

35 - 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.
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 - 18 dB
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.
500A External
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.

THIS IS CRAZY

September 24, 2005

These amps provide what I would call, "LEGIT wattage." No fake sony watts, no miss calculated numbers. This amp will really put out 5,000 watts. Just make sure you have 4 red tops, 3 200 amp alts, new electrical system. ETC. I sure hope you have sum good to put too it ;-) NOT FOR BEGINNERS!

Not for rookies!

July 30, 2011

I have been a Hifonics fan and consumer for many years before they bacame a big name. Always top quality and always big power. If you are a beginner - do not think you you are going to just drop an amp like this into a stock charging system - you will have nothing but problems. You must be sure to have enough power within your car to push the amp or you will end up with bad results and a car that oesnt start. I have 2 of these pushing 4 Hifonics Olympus olm-2412's and i actually ended up breaking my rear window before i had to turn it down. It will push whatever you want - and will handle alot of abuse. This is not a little Fosgate or Xplode - this is a big boy toy so take the right steps in installation or have it professionally installed and you will be extremely happy and never get rid of it.
