The easiest way to add high-output, low-distortion bass to any car audio system is with the JBL® GT-BassPro12 – a powered subwoofer that pumps out car-rocking bass through a design so cool you won’t want to hide it in your trunk. Simply put, it’s a complete subwoofer system for your vehicle. Its patented Slipstream port design delivers deep, bottom-end bass while minimizing port noise. Its woofer features improved motor-structure venting for thermal protection and a progressive spider to ensure superior mechanical reliability even at the highest output levels. Its amplifier delivers maximum power and the flexibility to connect to any factory-installed or aftermarket head unit. And with the system’s included remote level control, which lets you adjust the bass level from the driver’s seat, the only time you’ll need to stop is for gas.

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.

Rated 5 out of 5 by from Boom, Boom, Pow! Wow... I coupled this GT-BassPro12 with JBL GT638s in my 2011 Jeep JK. WOW!!! you get as much bass as you want. This powered subwoofer is incredibly easy to install and fills the space in my JK with way more bass than I need (seriously... I am 43); but, put Beastie Boys Intergalactic on and I feel 28 all over again! The box will take up most of your space in a Jeep - so, be prepared. Bigger cars will have no problem. The amp comes with all the important bits like bass boost, crossovers, and a remote that is easy to hide in the glove box. I love this subwoofer system.

Rated 5 out of 5 by from Amazing bass in a deceptive package! This combination is perfect for addition to a stock car sound system as it is self contained in a compact smart package. From the auto power on to the built in high level inputs, the convenience is unbeatable. Over and above that, the sound is amazing! The remote level control is a must because this is simply too loud for conventional commute trips, but when you need to crank it up, it certainly turns heads! Be sure to check he youtube videos for the car shaking that this little sub can produce. The power ratings may seem low, but it will blow out conventional 1000W subs from other manufacturers. The built in amp shows no strain whatsoever, barely gets warm even on a spanking hot day, class D technology! No battery drain or dipping headlamps either. For this price, you will never get a sub woofer and amplifier of this quality and this is entry level JBL! Can only imagine what their premium subs can do, but this is MORE than sufficient for the average joe that isn't looking at sound competitions. The box and port are also premium quality, the slip stream port eliminates baffle noise completely and is perfectly tuned for the sub and amplifier. This plays low notes that I didnt know existed with some of my old music! Right down to 30hz is very audible, but the box and port are tuned to 45hz, which it loves. HIGHLY RECOMMENDED!

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.
