Summary: For an 8" sub it is very powerful and sounds great. It fit in my Tahoe's original sub box and is being powered by a Rockford Fosgate 500 watt mono amp(it seems like it could handle much more).
Excerpt: The original driver in my Bazooka 8" passive tube rotted away from age. I found the JBL GT0804 fit perfectly (almost) and bought one. Just finished testing it after the install and it sounds great. At least as good as the original. Probably better.
This sub sounds amazing and punches in the chest like much larger subs do!!

Summary: Im in love with this subwoofer!!! Ive tried using a single image dynamics ctx104 10", a single sundown audio sa12-d4 12", a single kicker comp 15", and then this single 8" sub. Of all the different subs, this one sounds the best by far.
Excerpt: I installed a pair of 804's in my 2006 Tundra. I used the 804's because of limited depth under the rear bench seat and have them powered with a 1200 Watt JBL GTO amp and they ROCK!!! Great power and very clean too!!!
