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.

Just what I was looking for!

This amp is amazing and I have to agree the 3 channel is perfect for what I need and this amp is amazing. Pumps out clean power and fit just where I needed it to. (Though it is bigger than it looks in the pictures, just check before if it will fit where you want it to.)

Mounted on my spare tire in my scion tc. Powering the nvx component set and the nvx v subwoofer 500rms at 2omhs and it slams! (I'm very happy about the nvx products as well)

Sonic is the best if you don't already know by now, but back to the amp. The "EZ" setting gain LEDs are extremely helpful and I really enjoy that I have that feature. Also this puts out amazing power and only takes an 8 guage wire kit which was perfect. I am a big fan of JBL and NVX now. This amp is more that likely putting out more than it's rated for, just clean power. Very, very happy.

Great Amp

I have this amp pushing a soundqubed sdc2.5 12 and it is loud, I connected my four factory speakers and they sound great. I have had this amp for 2 weeks and I haven't had any problems, I highly recommend it!!!!

Perfect for trucks

I got this for my truck, it runs a pair of JBL Power coaxials and a pair of GTO subs wired to 2 ohms.

The power is outstanding. Way more than i expected. I'm not sure why there are not more 2 channel + subwoofer amps out there but this is exactly what i need in one amp. This thing is heavier and bigger than it looks in the pictures. I love the sound quality. I expect nothing less than a great product from JBL and this has lived up to the name.

I highly recommend it.

Perfect for my needs-well thought out amp design

I used this in conjunction with the GTO504 for a 7 speaker setup. this amp has plenty of options for a variety of situations. For me the auto-sensing remote took a few seconds to start, but it always worked fine. I now have a remote signal that avoids this, but I was OK with it when I was using it. The two different hi level and low level inputs worked great for me in two versions of my installation using both speaker and line level signals. If anything, the low level is very sensitive so if you are going in with 4V or higher I might recommend the hi level and using the gains to get it right. I had a hard time getting my minimum down.
The layout of the amps made installation on the back on my rear seats a snap and kept everything accessible, unlike most other amps. It also looks good when installed. Not flashy, but classy.The setup CD and step-by step process for setting the gains worked well but I had to dial it back quite a bit. However, that meant that I have lots of headroom on this amp and that makes me happy. I am driving Infinity Reference 6x9s and a 1062 DVC 10" sub at 2 Ohms in a sealed box. Plenty of power for that. The sub section is equivalent to the GTO-501 if you are comparing. If you have a need for a 2.1 configuration you can't go wrong here. Great value for the money.

Not very powerfull

Doesn't have much spl i connected a 750 4ohm 12' hifonics sub and 50 rms 4ohm speakers to the other 2 channels turned it to max volume and got disappointed by the lack of power in sound Its only an decent upgrade from the bad sound systems that are installed on almost every car on market i expected more for the relative high price of this amp , the sound its good but not goes loud enough , lack of power , it's a small amp they sacrificed the power for space better was bigger with more sound power than smaller with less power its also an big energy consumer its not class d i think that's why consumes many energy and produce small sound , decent sound nothing more . But i think the other alternative brands of car amps on market are not better than this for the same price .

JBL GTO 3EZ

This is my first amp and I would say it is fantastic. I have it in a Toyota Tacoma under the seat and it fits perfect. It powers my polk dxi 650's and one alpine bass line 12 and sounds really good. It was really easy to set up and tune with the JBL tuning CD. It looks great and sounds great! It was inexpensive and works great I would recommend this to anyone looking for this kind of amp and power range set up.
