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.

Power Specifications - Full Range Channels

Peak Power @ 4 ohms
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.

Bridged Peak/Max Power

Bridging refers to combining two channels on an amplifier to create one channel with double the voltage and an increased power output. A 2-channel amplifier will bridge down to 1-channel and a 4-channel amplifier can bridge to create 2-channels. An amplifier is most commonly bridged to drive a subwoofer.

Remember, once you bridge two channels down to one its final impedance will be 4 ohms unless otherwise specified. This rating lists the Peak/Max power created once an amplifier is bridged.

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.
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.

AB
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.
2 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.
0.05%
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.

32 - 320 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.
108 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.
No
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 4 
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.
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.
Hi-Res Audio Compatible
This feature refers to if the product is capable of Hi-Res Audio (HRA) playback.

A +++++ amp beats JL 1000/1v2 by far!!!!!!!!!!!!

April 13, 2010

like the previous review on here, he has the Mk II's with this amp i was trying to get those but ended up with Kicker CVX 12's instead, i'm sure the mk II's sound better but none the less this amp is crazy gooood!!!!!
Keep your grounds solid and short and use a cap , i have one other amp with this one, but i don't have any power issues at all, my lights don't dim or anything, just look at the specs on this amp it has a signal to noise ratio of 109, that's extremely good, i'm a specs guys, this thing beats JL audio, alpine, memphis, kicker amps, jbl is the same company as infinity and also Harmon Kardon, your getting really nice stuff when you order JBL and its priced good also.

I have two of these amps and do comps around the area. I have them running to four jbl mkii 12's. Hits 170's all day long. Just really you need to use either monster wire or Rockford wire. I prefer monster seeing how they're hands down the best. Use zero gauge and ANL fuses. You know it has power when it has four 40 amp fuses on the back. I have four optima batteries and four 1 farad caps and everything in my 03 impala dims. Broke the trunk latch lol.

BEAST!!!

January 2, 2009

I have this amp hooked up to two JBL P1222's in a vented box and a 5 farad cap and its insane. Even with my cap my lights still dim tremendously when the bass hits because this thing pulls so much power. Before this amp i had a two channel 2600 watt power accounting amp and it quit for some odd reason so i decided to go solid with JBL and I'm proud i did cause i've broken my trunk latch, the grills on my back speakers, and i can flex windows. So if your looking for a true 2000 watt amp or probably more for a good price you cant go wrong with the GTO14001.

This amp is amazing. Got it hooked up to 2 12w7 and you can hear me coming blocks away. I got a kinetic battery and my lights still dim as if i didn't even have it. I've owned over 6 amps in the last 2 years and this one out beats anything I've ever used. If your looking for allot of power and have the money, I highly recommend this amp.

February 10, 2010

IT IS A DAM GOOD AMP FOR A CLASS A/B. I GOT MINE OUT OFF THE BOX, IT WAS MOST POWERFUL ONE. I GOT IT HOOKED UP TO 2 Alpine - 12" Dual-Voice-Coil 4-Ohm Subwoofers that are 1500 peak and 500watt RMS EACH. SO AT 4 OHMS IT IS GETTING 1200 BUT MY AMP IS ON A LITTLE BELOW HALFWAY AND IT POUNDS THE SUBS ATLEAST 2 INCHES WHEN THEY BEAT. I WANT TO ADD ANOTHER SUB TO IT AND HAVE 3 12S BUT THE ALPINES ARE 4 OHMS AND THE JBL WILL NEED 1500rms TO RUN 3 ALPINES
HOPEFULLY IT PUSHES A LITTLE MORE THAN 1200 AT 4 OHMS BUT THEY ARE GREAT. I GOT A ALPINE DECK CDA-9886 IT GOES GREAT WITH THE ALPINE SPEAKERS DONT SKIP LIKE MY PANASONIC DID WHEN BUMPIN

First in response to previous reviews.. JBL International confirms this is a Class D amp not class A/B.. that is some debate.. this amp is under rated, and pushes a little bit more if you can keep your power stable at 14v.. its power hungry indeed.. do not use a cap, they are useless.. do the big 3 and upgrade your bat's.. It costs a pretty penny but you know what your getting and you know it will do what it says it will do..

I have one of these amps, when it gets to a certain volume or hits bump it'll go into protection mode and come back on once volume has been lowered, what might my problem be?
Spunky on Sep 17, 2014
Best Answer: Hello Clarence,

Unfortunately, there are waay too many variables to give you an honest answer. We suggest checking EVERY connection, specifically your ground points [including the points Under the hood]. If, after you've combed your system, you find No Faults, then it may be time to take the cover off and check for any loose connections. It is uncommon for any amp to lose strength in solder points, due to excessive heat. Your last resort, will be to contact JBL and/or an Authorized REPAIR Center.

Best Answer: Hello,

Unfortunately, your question cannot be answered. You provided a Brand Series and Size, but not the proper model number. Your description of the driver can mean one of at least six different models (see below). However, if your driver is anything But the more recent series and with a Dual-2Ohm configuration, then we wouldn't suggest attempting the setup. All the drivers have a power handling of 750w RMS, and clearly that amplifier is capable of far more than that, so be cautious.

i got this amp together with the JBL GX-A604, together with the GX600c 16.5CM 210Watts
the problem is, I cant connect those two amps.
everytime i connect thos two, the GX-A604 turns into a protection mode.
but if I direct my RCA to GX-A604 it works properly.

is it possible that they aren't compatible?

Best Answer: Hello Nic,

We aren't entirely sure what you mean by "connect those two amps" . You cannot connect two amplifiers together, per se. So what exactly are you connecting? Please only include information pertaining to the issue (for example, the speakers don't matter, so don't include it in the inquiry).
