Small and Powerful

The newest JBL GTO EZ Series car audio amplifiers provide unmatched ease of installation, configuration and calibration for clean, powerful sound. Connect to OEM or aftermarket systems without complicated adapters or setup routines. Use line-level (RCA) signals or speaker-level signals with RCA-to-bare-wire adapters. Experience the clean and powerful output of GTO amplifiers in a variety of channel configurations and power ratings, all of which are CEA-2006A compliant and backed by the JBL reputation for top quality.

JBL GTO subwoofer amps and subwoofer channels in system amps use highly efficient Class D circuitry to deliver very high output levels with lower current draw and lower heat generation. This high-efficiency circuitry is less taxing on your vehicle's electrical system, and the reduced system heat can enhance the amplifier's long-term reliability.

The full-range channels include a 40Hz to 220Hz variable crossover that's switchable for high-pass or low-pass operation (or bypass), and allows for precise tuning of the crossover frequency based on the speaker type and configuration being driven by those channels. Subwoofer amps and the subwoofer channels in system amplifiers feature a 40Hz to 280Hz low-pass crossover that lets you get the best blend between your system's subwoofer and the rest of its speakers.


The Sound of quality

Sonic Electronix, one of the leaders in car audio, recently visited Harman, the premium global audio and infotainment group, at their research and development locations in Northridge, California and Detroit, Michigan. The purpose of these visits was to utilize and combine the powerful brand of Harman and the industry leading knowledge behind Sonic Electronix to begin working together on developing future car audio projects.

Power Specifications - Full Range Channels

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 speakers or subwoofers 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.

50 watts x 4 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 speakers or subwoofers 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.

75 watts x 4 channels
Bridged RMS 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 RMS power created once an amplifier is bridged.

150 watts x 2 channels

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.

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.
GTO (JBL)
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 / 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.
5
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.

1075 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.

500 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
Minimum Impedance Bridged
The lowest impedance the amplifier will handle when it is bridged.
4 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.
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.
No
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)
High-pass (HP)
High-Pass Crossover Frequency
The high-pass crossover frequency can be a fixed crossover point or a variable crossover range. A variable high-pass crossover allows you to select a specific crossover point which allows frequencies above the set crossover point to pass, while making frequencies below 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 - 200 Hz
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 - 200 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.
85 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.
Optional (Accessory required and sold separately)
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.

Yes
Hi-Res Audio Compatible
This feature refers to if the product is capable of Hi-Res Audio (HRA) playback.

Great amp that does it all for a great price at that

January 22, 2014

I would highly recommend this amplifier. We had it installed in my wife's Civic to power her entire system which it does perfectly. I love, love the LEDs helping to properly set gain on all inputs. Good size and plenty of juice for four 6.5" Polk speakers and a vented 10" RE 2-ohm sub. I really can't say enough about this product. Well done, JBL!

Baddest 5 channel Amp ive ever purchased.

September 10, 2015

I've had 100a of amps some given to me some bought some on sale and this one is the clearest most powerful amp I've used . I don't want neighborhood shaking bars but if I want it'll do it. Crazy loud strong Dosent shut off when heated. And you know we have been having some zombie creating heat this last few months. Awsome price high quality and wicked wicked sound. Clear as day EQ works flawlessly even self tunes itself. I have a set of jBL bro component 6.9s a set of 6 1/2 JBL components and a new Pioneer slim 10 inch crazy strong sub crazy bars of you need it but clean crisp and ultra sensitive if you love that here all bass separation on hard rock dance old school rap hip hop no flaws here will far purchase this same set up for my 335i, very soon. WOW.... Extremely high quality great price can't go wrong, period 💯 ....

The Best Singular Solution Amp

September 2, 2015

I bought this amp because I am an old school A/B amp fan. This amp combines the crystal clear, low-distortion A/B amp for the front stage, and the high-efficiency power of a class D amp for the sub stage. I got my daughter her first car audio system for graduation, and she absolutely loves it. I was a little skeptical at buying a 5-channel "budget" amp, but I was very pleasantly surprised at this amp. I bought her a Pioneer DEH-80PRS head unit, a pair of Memphis Audio 15-MCX62 6-1/2" coaxials for the front doors, a pair of Kicker 41KSC654 6-1/2" coaxials for the rear deck, and one Digital Designs DD-212 SVC 12" 4-ohm sub in a 1.1 cf sealed box facing the rear in the trunk. This amp provides plenty of power on all channels, gets plenty loud, and is crystal clear on all channels. It also provides easy to use features to make adjustments to the sound on each set of outputs, making it super easy to sound perfect for the vehicle. I will definitely be buying another one for my wife's car! I've only had it for about three weeks, so I can't really rate its durability, but it is JBL, and the way I baby stereo systems, I'm pretty sure it will last for many years.

Awesome amp!

August 24, 2015

After much thought, and watching Steve Meade test JBL amps on Youtube, I decided to go ahead and give this amp a try. This amp is CEA-2006 compliant which definitely helped my confidence that I was buying a product that does what it says it will do. The result is the best single solution out there to power a good car audio system on a budget. If you want good clean sound for the front stage, this amp provides it with the CLEAN (50W @ 4-ohms) A/B wattage on the front four channels. It also provides plenty of power to drive a top of the line single sub, or even a pair of subs. This amp actually DOES WHAT IT SAYS IT WILL DO, and at a bargain price! I love this amp, and will be buying another one for my wife's car. You can't go wrong if the specs are what you need. It fit my needs to a tee. I can't rightly give the product more than 3 stars for durability as I haven't had it but a week, lol! I'm pretty sure it'll hold up, though. Everything else is 5-star all the way! Great job, JBL, for a quality product at a bargain price!

WOW!

August 25, 2015

Folks, I was on a strict budget and needed as small of a footprint as possible for my daughter's Kia, so I bought a 5-channel amp for the first time. I was pretty skeptical about getting "enough" sound from a single amp, but after installing this amp I was simply amazed! My daughter is not a "bass head" like I am, but she does appreciate being able to clearly hear every note without distortion. Boy, does this amp ever provide it! The A/B portion on the front 4 channels was a must as that is where distortion is most audible. I have a set of Memphis coaxials in the front door, a set of Kicker coaxials in the rear deck - all 6-1/2", and a single Digital Designs 12" in a sealed 1.1 cu. ft. box in the trunk, all running at 4-ohms, and this thing will get LOUD and CLEAR on the front stage, and hits hard and deep on the low end. All of this is running through a Pioneer DEH-80PRS as the head unit. I could get much more bass with this much power, but I was looking for SQ moreso than SPL for my daughter. If I had two 12"s running at 2-ohm in the trunk of her car, I don't think any of the mirrors would stay attached. I did my research on Youtube to see if JBL amps did what they say they do, and the amps checked out by Steve Meade exceeded the rated wattage. I'm definitely a believer now! Great job, JBL, and affordable, too? I can't only give a 3-star on durability at this point because I haven't had it hooked up but a few days, but I'm pretty darn sure it will last many years. WOW!

Great Amp, Good power

September 4, 2015

Bought the JBL 5ez from sonic electronix for an unbeatable price. With an amp kit. It has been worth the money so far. Puts out better power than I thought it would and sounds great. I don't think you can do better for a 5ch amp at this price. Sonic electronix had the best price on this amp by far.

The biggest thing I noticed is how hard my subwoofer (JL Audio W6v2) hits on this amp. Really hard hitting bass that can damage your hearing if your not careful. Pounds the sub to the point where the speakers can get drowned out if gains are not set right. Clear clean loud and low. This amp is all you need for a decent car setup, got enough volume to damage your ears and can play consistently. My speakers sound pretty good (JBL Gto's) on this amp but not quite as loud as I would like them to be. I turned the sub down to match them since the sub can get much louder than them. Dynamatted both doors and rear decks, I may dynamat the trunk one day now.

2 cons to the amp though:
1st: It gets pretty hot. Playing this amp for an hr at moderatly high volume it will get hot. Hot to where you can't put your hand on the amp for over 5 seconds or it will burn you. I had amp professionally installed and have been asking on forums about the heat, most say it's normal since I'm running it at 2ohm impedence. It's ok to me if it's normal that the amp gets hot, I just don't like any of my electronics getting hot whether its normal or not. One thing I am worried about and am keeping my eye on.

2nd: The JBL 5ez setup cd is trash. Just throw it away as soon as you get it and set your amp on your own. Using the test cd and following instructions to a T, I set the amp to make the led's green at 75% max volume. Problem is, when I played some music and could only turn up my radio maybe 50% before clipping occurs. (Music is released much louder these days than the low volume test tone) After a few days of this, I said screw the test cd and reset the amp by ear around 75-80% volume with music. Turned the gains way down on the amp and now I can get around 75-80% volume from head unit playing music without any clipping. I'm not sure where my head unit clips so I'm settting it being safe. I could push it harder but I don't have a tool to test for clipping, so I just set it conseratively. Setting it by ear is way better than using the test cd. Not even sure why this amp was marketed like this. But it's ok I still like the fact that the gains have a dial, and not some screwdriver hole where you can't even see where your gain is set.

Overall its a great amp 4/5, for the price offered on sonic electronix its 5/5. Lets just hope it lasts me!

This is a well built amplifier, looks nice,and has plenty of power for the most demanding audiophile. Not quite as small as a PDX v9, but not as pricey. With that said,it can hold its own against the Alpine.

perfect 5 channel amp

September 15, 2015

I'm going to write a review for this amp and a sub I ordered. First the amp I replaced this one with a very weak fosgate 5 channel amp. This amp is impressive I'm running a set of Memphis components and Memphis coaxial in the rear was using the sub channel to run a jl audio 10w3 and the sub would bottom out on the 500rms in the factory location so took that one out and dropped in a re audio scx 10d4 and i will tell the re audio will beat the jl in every aspect in the same factory location the amp has the right power and the sub wants more. So anyone looking for a good combo without spending alot get this amp and the re audio scx sub that sub can hit lower than the pricey 10w3. I wish I could do a video of the sub but the grill covers it but it hits so sweet now and its not even broken in yet.

I finished my install this weekend. All 4 speakers amp and sub matched by Sonic. the sound is great but I get a constant low volume high pitch ring. it does not fluctuate but is always there. any thought on how to get rid of it?
brian c on Nov 2, 2015
Best Answer: Try unplugging each set of RCA's to see which are bringing noise into the amp. If you find it is in a certain pair then a filter will be needed. If the problem does not show up there make sure you have a good short ground and all of your high power wires are clear of your signal wires. I had the issue on my sub channel RCA input and had to put a filter on it. It did slightly dampen/lower my input signal but it was worth getting rid of the hum. I ran my sub RCA's down the side of the truck with the power wires as it was too short to go the long way around like the others.

If you are running the subwoofer on a final impedance of 2 Ohms, do the other 4 speakers need to have a final ohm impedance of 2 ohms also?
A shopper on Sep 25, 2015
Best Answer: No if you have a five channel amp and your sub channel is only stable at two ohms then that is what you want your sub to be to get the most power out of that channel. Now the other four channels can only be 4 or 2 ohms meaning 2 is the lowest your amp is stable. Four ohms will get you half power and two the most it will push. The sub side doesn't have anything to do with the other four channels.

Best Answer: Hi I'm not sure what you are asking here. I can say that this is a mono block amp. I'm using my sub L & R outputs from my head unit to the input of the amp.This then powers my dual coil sub woofer for bass only. The inputs are not high inputs and are only RCA jacks.Hope this helps you.

which component speakers and subwoofers can I use with this amp GTO-5EZ?
Evans R on May 21, 2015
Best Answer: It can power any components you throw it's way. Alpine TypeRs or Infinity Kappas would be my choice. If memory serves me correctly, it pushes 500w rms into a 2 ohm load for the subwoofer. So any subwoofer rated at 500 watts RMS with a final 2 ohm impedance load will work. I had it pushing a 12 JL W3 and it sounded great. Hope that helps.
