Some subwoofers are meant to be seen as well as heard. The GT-12BP features an acrylic window shaped like the JBL exclamation point and orange illumination, so you can look into the enclosure and see what legendary bass looks like.

Description

Some car audio fans love the clarity of sealed subwoofer enclosures. Others crave the added power of vented enclosures. The GT-12BP bandpass subwoofer offers both. It delivers accurate bass response and thundering power—as well as a bold look. The stylish box features a look-in acrylic window shaped like the JBL exclamation point, making the GT-12BP as appealing to the eyes as it is to the ears. And the sturdy enclosure shields the 12-inch polypropylene woofer from items that might shift in your trunk. The great value GT-12BP proves you don’t have to spend a fortune to enjoy legendary JBL bass.

Rated 5 out of 5 by from Bring the thump! Running 2 of these in parallel at 2 ohms with an Orion 1000.d XTR amplifier, these things absolutely slam. Great punch with Metal and superb lows with hip hop and dubstep. Have both firing to the rear in a sound deadened trunk, highly advise you do this as the acoustics are improved immensely. A little big because of the bandpass design but absolutely worth it if you have trunk space to spare.

Asked by: Prad12345
@ Joe G at Customer Service - The Synthesis has a Subwoofer already which came along with the sound system - I was wondering I could bypass it with this one. Will I still be needing the amp if I'm using the channel ?

What speaker is in the box? Also does the S3-1224 12" fit inside this box?

Asked by: CaneCorso
The speaker inside was designed specifically for GT-12BP, and the S3-1224 can theoretically work with the enclosure; however, we have no way to confirm that it will sound as good.
