Reduced-Depth, A Full Inch Shallower Than Most

A new, JBL-proprietary frame, unique inboard motor structure and new cone design create a woofer that is a full inch shallower than competing brands’ equivalent-sized models, expanding installation options. You can drive a compact car with sound that’s anything but compact.


Exceptional Venting For Increased Power Handling

Woofer motor structures heat up during use, causing distortion or power compression that reduces music’s dynamic range, robbing the sound of its realism. JBL uses vented motor structures and polepieces that get rid of more heat to deliver more serious bang.


Outstanding Audio Output, Low Distortion

With 200 watts RMS and 800 watts of peak power handling and a frequency response of 30Hz to 400Hz, the GTO804 changes the experience of listening to your favorite music in your car. And a progressive spider gives better control for lower distortion at excursion limits.

My car (2012 buick verano) was originally equiped with a bose sound system that sounded pretty well but needed some more sub-bass to suit my music taste, so i bought two of those 8" subwoofers that I installed in fiberglass custom made boxes (0.35cuft) and drive those subwoofers with 200wrms/woofer. This way i didn't loose any usable space in the trunk but got enough bass to sound exactly like a good 12" subwoofer without having to use a uge box. Those little subwoofers pound hard and provide excellent tight and acurate bass.

This is a fantastic sub! I have it hooked up to an old-generic-200watt amp and it definitely exceeded my expectations. It is well worth the money and in my opinion it kicks like a sub of larger size. The deep bass tones are very nice!

This sub is a single coil with low rms. I have it on a crossfire 600 watt amp and for only getting the 500 ish amount of watts it plays 30hz bass notes with authority. It's a killer sq sub and I would recommend it to anyone looking for an 8
