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.
500 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.
1000 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.
1500 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

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.

1500 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
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.
0.95%
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
Fuse Rating
The amperage and the number of fuse(s) an amp requires.
70A 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 amp

August 29, 2011

Great amp it pushes four 12" kickers hard. this is a great amp if you are looking for this power. i also had a power acoustic 4000 bamf and the hifonics pushed the subs harder. the only problem i had was the allen wrench terminals. i couldnt find a allen wrench that fit right.. but once i fiddled with it and got it secure it was great.

I recently purchased this amp to power my 2 15" Alpine Type S subs. I am running the amp at 1 ohm, and it slams! I do not regret buying this amp yet... I've had it only for about a week. So far so good, sounds great and doesn't get hot. I'll post a review about it in the future. As for everybody saying that it sucks power.... I have 1 battery and thats the battery under my hood, 4ga wire, and stock alternator in my blazer, the voltage doesn't drop very bad at all don't worry about it.

Good amp

September 16, 2014

After seeing good reviews on several different models of Hifonics, I decided to try one out. I went with this series, and although not being CEA compliant (didn't know till afterwards) it did not disappoint. I had it hooked up to a 24 pound Soundstream 12. The sub came alive and destroyed my car. It was pretty sick. Amp really got down with the lows and kept it there. Got a little warm, but never cut out or distorted. Hooked it up later to my buddies fifteens and they hit harder than the 1100.1 Memphis he had previously bought used for twice the price of this amp. If you're thinking of going with Hifonics I'd say yea do it. Dollar for dollar, no other brand has it like Hifonics at this moment. Satisfaction.

Listen man, Hifonics has been in the game a long time. I've owned multiple amps from them over the past 15 years. I come from the Bay Area where we all grew up on music from Too Short and E40 thru the 80's till now. For those that understand what I mean by that, their music came with heavy baselines and that hard hitting 808 sound. In order to push their kind of music in our cars, you had to have the power to do it. Look no further. You've found the amp that can do EXACTLY what I've stated above in addition to a getting great value due to the price. You won't even have to take it to 2 or 1 ohm. Get you a pair of 12's, which I have (Hifonics HFX DVC's) and run it at 4ohm in a sealed box. It will be more than enough. Trust me.

Amazing Amplifier

August 18, 2014

I am using this amplifier to push 2 JL 15's, they are 500 watts a piece, and wired parallel to drop the impedance to 2 ohms. It does very well pushing 1,000 watts at 2 ohms. I ran 4 gauge stinger pro series wire to it from a single xs 975 replacing my stock battery, not even using a power capacitor, and no headlight dim. This amp is very efficient and will make your subs slam. And it hardly costs anything.

Bought one from Sonic in 2010, and I had it on a pair of Kicker L5 10's I also purchased from sonic. It works very well until I was bassin in the rain, trunk was flexin so hard that water got into it. Unfortunately water damage is not covered under warranty. If you want bass that flex everything and makes your wipers bounce of the windshield, get it.

November 16, 2012

I'm running 2 10' cvr's at 1 ohm and I have to be careful as it is overpowering the subs especially playing high crest factor music.Not sure if it is a true 1500 rms at 1 ohm but it definitely is well over my required 800 rms. Clean crisp bass response that is close to, if not better than my RF 800a2 that almost $1000 new. Doesn't even seem to warm up.Good on you Hifonics!!

Haven't tested the db level, but I'm sure it's close to 140.0.

I just purchased this amp.. hifonics has always been great.. I bought it to power the new 2014 Memphis mojo 12'' 2ohm it seems like it is pushing good but my sub sound scratchy at low volume and just before the beat hits sometimes the amp will protect and then come out of protect when I turn the bass knob down all the way.. not sure whats going on here?
nicholas s on Aug 27, 2014
Best Answer: If your subwoofer sounds scratchy, it is possible that the subwoofer coil is scraping the magnet. (The woofer may be bad). If you have a Voltmeter, check the resistance of the woofer and make sure it is close to 2 ohms. (1.8 - 2.2 ohms approx is okay). Any resistance outside of what the amp is rated for will blow the amp.

It is possible that the amp and sub were not tuned correctly and listening to music too loud melted the coils of the woofer (resulting in the scratching sound and low resistance of the woofer causing damage to the amp as well)

If the woofer is okay with the correct resistance, then check all the wiring and make sure the + and - are connected the right way.

If everything seems okay, then the amp may be bad, although highly unlikely.
