After all, it is not every day you come across a product in Amazon, which scores 5 stars and thumbs up from all the satisfied customers so far.

Product Features

JBL GT-BassPro12 is a 12-inch or 300mm sized audio system for the car that nestles in a die-cast aluminum pocket. The polypropylene body cone also gets rubber on it to ensure that the sound resonates and music quality is unimaginably good.

Imagine that you are going out with your friends and the sound system is somehow not sounding as loud as it does when you drive alone in the car. Probably your car audio is not the JBL GT-BassPro12, which also gets a 150-watt amplifier. The sound will not be jarred or loud in one side and barely a whisper in the other end of the cabin.

Rather this amplifier helps in ensuring that the music from this subwoofer is uniform throughout. The speakers sit comfortably in their designated bars which shall ensure that even as you drive through bumpy roads, your journey will remain as musical as it was.

The Progressive spider ensures that the listener gets full control of the cone just so that they get to listen to the music exactly as they want.

It is hard to come across Bass sound system, which excels in offering a very little distortion of speaker output at high volume too. But this is exactly where you shall find the car audio satisfying.

What’s unique about this car audio system?

JBL GT-BassPro12 is a top ranking car audio powered subwoofer system, which comes with several features and a bunch of attributes that make it very attractive. There are a few people who enjoy listening to loud peppy numbers on a long drive with friends. For such music lovers, the JBL GT-BassPro12 is ideal.

The product’s very own Slipstream port forms a barrier that does not allow the noise or distortion even at high output levels. The design of this patented Slipstream port is suitable to reduce any kind of noise and disturbance in the music output. Therefore, the users are thoroughly pleased with this product.

Another feature that makes this subwoofer stand apart is its inbuilt amplifier. Setting up this subwoofer is also quite easy, and since it already has an amplifier, it would not be problematic or more of concern to get them additionally.

A unique thing and yet a very obvious fact is that the subwoofer gets a polypropylene cone body that gets oversized speaker bars and amplifiers that are inbuilt. In short, this is a recipe for perfect audio output without any unnecessary hurdle or distortion whatsoever.

The Vented Polepiece is an attribute that this subwoofer comes with, which ensures that even in low compression inside the cabin, the music’s quality does not differ and you can enjoy your Bach with as much of same pitch and melody.

Another feature that might be unique is the Automatic on and off mechanism at the speaker level to help the driver to focus while waiting for a signal to turn green. If you are a rough driver and do not mind taking the rough road uphill and are worried about the speakers coming off their slots, do not worry about that too.

Listening to classy music from JBL’s audio system is a pleasure that everyone would love to indulge in, and that means the woofers would evenly distribute the music through the cabin and give you immense enjoyment.
