The JBL® GT-BassPro12 powered subwoofer pumps out lush, car-rocking bass through a design so cool you won’t want to hide it in your trunk. The patented Slipstream port design delivers deep bottom end while minimising turbulence.

Turbulence, or port noise at high volume, isn’t just annoying. It’s a signal that the port is no longer working and you’re getting less bass than you paid for. The Slipstream design is carefully optimised for the combination of woofer, amp and enclosure, and no other company has it.

And with the included remote control for drive-time adjustments, the only time you’ll need to stop is for fuel.

Rated 5 out of 5 by from Easy to installl It took me a while to install my sub because I'd never sone it before. After watching several videos and getting the necessary equipment , once I made time it went very easy. When that green power light came on and I adjusted the levels, I was very happy with the bass it generated.

Rated 5 out of 5 by from One word....incredible. Want your jimmies rattled? Then look no further. This things gonna shake you to the core with the bass it puts out. And don’t even bother wearing socks while driving with this thing playing, cuz it’ll blow em right off. Amazing 2-in-1 unit, decent price, and the volume control knob is incredibly handy. Bass is very loud, deep, and clean. Highly recommend. Very fast shipping too, arrived in just 2-3 days.

Rated 5 out of 5 by from Best buy I've made in a very very long time! I'm in love with this speaker. It's way more powerful than I ever thought it would be, and its such a clean and controlled thump. Sounds awesome with any type of music. I simply added this speaker to my factory 2017 Camry, and it made all the difference in the world. Sounds like a $1000 system now.

Do I need a fuse for the battery wire, is it really necessary? if so will an 80Amp fuse be safe to use? Because there is a fuse on the back of it. Thank you

Asked by: makaveli08
What would happer perhaps if the battery wire going to the sub in the rear of the vehicle were to develop a fault? Nicked, cut, or inadvertently grounded? No fuse at the battery on the wire at the very beginning means your car goes up in flames. ALWAYS fuse the very beginning of the wiring going to amplifiers elsewhere. Just a tip.

Will this fit in my Dodge Dakota?

Asked by: Matthew7906
Hi! The JBL GT Basspro 12 is quite big and deep for the Dodge Dakota, we would recommend a smaller 10" subwoofer instead. For further assistance, please submit a case request at https://www.jbl.com/support-contact.html and the Customer Service Team will be more than happy to assist you.

I currently have one of these in my trunk, however was sondering if I can add a small say 250 to 300 watt amplifier to the sub to give it a bit more oomph...really will it be able to take the extra power

Asked by: Kiecam
Yes you can. It should be able to give you more bass when used with an amplifier, provided that the power ratings don't exceed the specifications provided..

The sub is great. I worry about the speaker getting punctured though in my trunk. Is there a grill that you could recommend? Thanks!

Asked by: Traci
Hi Traci, thanks for reaching out. Our JBL GT-BassPro12 comes with a pair of metal grill. If that's not enough to protect your subwoofer, you can purchase a waffle grill for a 12 inch subs from third party sellers.
