Big Bass

For anyone who likes to crank it up in the car, the new JBL 12" high-output GT5-12D subwoofer is the real deal. The JBL GT5-12D subwoofer features a Dual 4-ohm voice coil and a vented motor structure, and offers 1100 watts of peak power handling. The GT5-12D also features JBL’s newest design, combining classic elements with modern ones.

All-New Design

The GT5-12D follows the design of the more-expensive JBL subwoofers, combining classic elements with modern ones.


Significant Power Handling Capabilities

The GT5-12D handles 275W/1100W (RMS/Peak) power and offers nearly 20 percent higher Xmax than many competitors.


Increased Reliability

With its fully vented motor structure and rubber-coated tinsel leads, the GT5-12D is able to withstand even the most intense bass assault.


Dual-Stacked, Oversized Magnets

Unlike competing entry-level subwoofers, the GT5-12D is based on a solid motor structure featuring two large magnets covered by the classic JBL rubber ring.




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.

Good Sub, Bad set-up

This is an awesome sub, it has great sound and for a 1100 watt sub it hits hard, the downside to it is that after a while of it being up loud, the plastic part in the middle, with the JBL logo on it comes loose and makes it sound bad because it vibrates and causes a high pitched rattling sound.

Bargain

This woofer is awesome for the price i paid...less than $60...here at Sonic...it sound fabulous in a 1.75 port box...but it will only hold around 400-450 watts RMS....after that the voice coil starts heating up and stinking.

Great Buy LOVE JBL's!!

I bought a 2004 gmc yukon and i wanted to premium sound into it. so I decided to go with JBL's because they are a popular brand sound for good quality sound. These subs did not let me down. Especially for the price!. I do not regret getting them. I highly recommend them to anybody. And i still havent broke these in yet. Just put them in today. Especially if your starting off you will not be let down. Guarantee!!! If you want true power you can like i did which was bridge them at 2ohms so i was pushing 550RMS with both subs. sounds amazing!!. I powered them using a 1200watt 2channel 580 rms AMP baught a refurbished amp. Used 4 Guage 2500 watt kit. If you do a clean good install and tune the amp right. You will not be disappointed. 5 STARS!

great subs

I have two of these in my Ford Focus and they are amazing! I would recommend these to anyone who wants great bass and great quality with low cost. I have them hooked up to a 2 channel 2500 watt Boss amp and I have had no problems in the past year and I turn them up everyday. definitely a great buy and I will buy them again if im doing another system
