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.

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 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.

2000 watts
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.

1000 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.
Any Gauge with use of Spade Terminal 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.
Yes
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)
Subsonic
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.
20 - 50 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.
40A x 2 
Strappable
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.
Yes
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.

Awesome Amplifier

March 11, 2016

I have two of these amps powering 2 15" Solo-Baric L5's which are 1500 watts peak power a piece it powers both of them no problem. It has tons of different adjustments you can make so that you can make your sub woofers work to their optimum level its has a great design to help it keep airflow through it as long as you have cooling fans on it. Great amp for a low price.

December 2, 2015

I was a bit skeptical going with this sense there aren't any reviews anywhere, i think the amp is too new or something. idk . Anyway, the amp has the exact RMS I need for my setup at 2 ohms and it isn't very expensive, so I decided to pick one up. Im glad I did because the amp rocks exactly like it needs to! I'm driving an old school rockford punch dual voice coil 12" and this amp makes that baby bump!

1000w RMS @ 1-Ohm Monoblock in a Small Package

April 9, 2016

I finally traded in my 1998 F150 regular cab with (2) Memphis 12"s & a Memphis 1100w RMS monoblock up to a 2012 F150 XLT Crew Cab. This meant fewer options for me for subs & sub box, etc. So...I decided to go with (2) DVC 4-Ohm NVX 10" subs (sub box volume: 0.8 ft³ per sub) and this little monoblock amp. Now, my old Memphis system kicked major butt, so I was expecting the bass in my new system to be a major downgrade....you know, the price I had to pay for getting a newer truck. What I was NOT expecting was the surprisingly hard-hitting bass this new setup puts out. I was pleasantly surprised.

I definitely recommend this little amp 100% for (listed) 1000w RMS for less than $100. I haven't actually put it on a dyno for actual, measured output power, but it does hold its own with other amps I have owned, especially for the size.

I got this amp for just under $150 and I think I'm going to grab another one now that its on sale. Easily the best item I've picked up from Sonic! I used this to replace my old Kicker 600 watt and holy S*** it blows it out of the water! Obviously it's more power but MAN is it more power. Great buy!!

October 17, 2016

I would definitely recommend this amplifier to anyone looking for a cheap start. Pushes my 2 4ohm dvc 400 watt rms 15in subs better than any amp that I've owned safely at 2 ohms, and the bass knob is just nice to have.
Great amplifier for cheap price, also it hasn't cut out or over heated once.

This is a small form factor amp that delivers the power without getting hot. It has two 40 amp fuses so it does roughly 800 rms. Consider me old school without voltage meters and smds lol. But really this is a nice amp for the price. Dont underestimate crunch because anything that has maxxonics on the brannding is pretty good.

Best Answer: At 1st glance without doing a ton of research: A single DVC sub @ 2? with RMS rating of 1000W wired down to 1?. This matches the RMS of the amp: 1000w RMS @ 1?. I have this amp and it it quite powerful... Granted, that's at 1? pushing (2) NVX 10" subs (DVC at 4? each).

I guess the short answer is yes; the RMS specs seem to match on both.

Best Answer: Hi Steven,

We assume you are referring to the Rockford Fosgate P2-2X12. ("Rockford p2?1600watt max" is not a model number). Of which, specifies a Recommended power range of 600 - 1000 watts RMS @ 1-ohm in the description.

The Crunch PDX-2000.1D specifies 1000 watts x 1 chan. @ 1 ohm, in its description. Therefore, yes, it will 'push' the drivers adequately.
