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.

GT-BASSPRO12 is rated 4.0 out of 5 by 11.
Rated 5 out of 5 by from All around, Great This product is all around amazing. Loud, clear, and deep bass. Easy to install. And the remote control and the built in amp is something that everyone wishes they had. It has a fresh look sitting in the trunk. I would highly recommend it.

Rated 5 out of 5 by from Wowwed by both the performance and reliability Been using the JBL GT-BassPro for the last 2 years and am very satisfied with its performance and durability. I like my music cranked and this subwoofer gives me what I want with no complaints. From Classical to AC/DC it fills the bill in my 300C.

Rated 5 out of 5 by from Best sounding and least expensive of any I've had My weekend car is actually garaged at the moment so I'm using it in my home entertainment system. Powered by a 500 watt computer power source. It sounds great. The remote is nice. I've spent twice as much and not been as happy.

Does it have an inbuilt 2 channel or 4 channel amplifier? if it has a 4 channel amplifier then it can be connected to the other speakers in the car?

Asked by: Namin
The built-in 150W RMS amplifier in the GT BASSPRO-12 is dedicated to power only the subwoofer. It does not have other outputs that you can connect other speakers to.

Im just curious what the best amp installation kit would be for this sub Thanks!

Asked by: Chris111
The GT-BASSPRO12’s Owner’s Manual available on this product page under Manuals & Downloads would indicate the recommended wiring gauge to use. This will also help you determine the type of kit to use depending on your existing car system.
