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.
1000 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.
1400 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.

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.

3400 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.

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.
.05%
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 - 150 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.
100 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.
30A x 3 
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 D class amp, it was easy to install and everything is labeled nicely so tuning it to get the best sound was easy. Bass remote reaches from my trunk to my front seat no problem which is great for quick adjustments on the go. Only problem I've had was I didn't have a solid enough ground connection at first and there was no indication to show that was the problem. I now feel the Bass boom with this great amp.

Best Answer: Bro, i'all be honest with you, I was running this amp at 4 ohms which is 1000watts RMS. I have 2 pioneer ts-w3003d4 let me tell you, I was shaking my house! Then in decided to go ahead and wire them to1 ohm....... BOOM!! - Get some sound deadner if you are gonna run this amp at 1 ohm, and a second battery. I can feel my arm and face hairs shake. Has very earth quaking lows. Good amp.

I have 2 10" American Bass xo1044 subs that have 4 ohm DVC, I believe that are rated 350 RMS each, would any of these amps safely drive these subs without killing them?

Best Answer: Yes the RZ1-2300D could eaisly drive them without over driving them. Generally you wnt about twice the Rms power of your speakers. Yours are 350 Watts RMS so any amp thats 700 watts RMS or a littler more would work fine. You do not want to turn the gain more than 70% on the amp. Distortion is what fry's speakers. You want the lowest harmonic distortion amp with the most rms power, NOT PEAK POWER. Hope this helps.

I have a very serious question, I am looking to use this amp on 2, 350 watt RMS subs at 4 ohm , I am looking to make a very balanced system, hard hitting bass with clean (VERY CLEAN) audio, nothing sounding like some of these rattle boxes. I am looking to use this amp SPL GLA1-3400D for my subs and a 100rms per channel 4 channel amp for my mids and a 4 channel 50 RMS per channel amp for my highs. right now I have just stock speakers and 2 stock tweeters, would this amp be too over powering for me to use right now with my stock system or can I turn it down enough to where it would be just right for now until I make my purchases for the whole system?
Black Raven on Feb 3, 2015
Best Answer: Hi Kyle,

There are few issues here: First, descriptions - "2, 350 watt RMS subs at 4 ohm" - isn't going to help us provide you accurate information. If you can provide proper Model Numbers, it will ensure that we are on the same page. Next, if its truly "clean audio" that you seek, you aren't going to get that from entry-level product/brands like the SPL GLA1. Such products are intended to "get the job done" and be budget friendly; They are able to accomplish that by cutting many corners. That isn't necessarily a bad thing, but it certainly isn't going to get you "VERY CLEAN" audio. As such, the figures this amp claims are likely a bit more ambitious than the true figures it is putting out. Not being CEA-Compliant means that the figures may very well be far off, and considering the fuse rating is a modest 30Ax3 , its far more likely that the amp is providing 'real world figures' of roughly Half that that it claims.

To answer your question, however, hypothetically, if this map truly put out 1000w RMS @4ohms, but your setup only requires, 350 x 2 , 700w RMS and the latter is the figure we are working with, then it is fairly unlikely that the low end is going to completely/dramatically drown out the or "overpower" the OEM system. Moreover, most amps provide a Level Control, that you will be able to use to balance the system so that doesn't happen.

Just a reference, if you were to call in and ask which amp we would recommend that fits your application [i.e. Clean Signal w/ ~700w RMS @4ohms] , it would surely be an amp like the JBL GTO-1001EZ, Kicker DXA1500.1, or Kicker KX1600.1 (in order of Quality of Output) .
