Description Hear and feel real power with the JBL GT4-10 1000-watt car audio
subwoofer. A polypropylene woofer cone delivers exceptional attack resulting in incredibly tight
bass response. Butyl rubber surrounds offer ideal cone-edge suspension and guarantee long-
term reliability by rejecting moisture and ultraviolet contamination.
12mm Linear one-way X-max and dual 40oz (80oz )magnets make this subwoofer a great
choice for high output applications. A progressive spider design provides better control at
excursion limits than more commonly used linear spiders.

i received 2 of these subs about 6-7 yrs ago as a christmas gift. they are still working! destroyed my bandpass box though! i love them now im looking to replace more of my speakers w JBL! Becky orlando, fl
i got 2 of these subs on brand new. i also got 2 boxes for them. i put a kicker 1500 Watt amp on these and they BUMP! i've had them for about 2 years ago and there still is no cracks or tearing on these. these are some really nice inexpensive subs and last a long time. i will recommend these to anyone who is looking for subs and wants something that hits hard. really nice:)- DECKER Fort Worth, Texas
I REALLY LIKED THESE SPEAKERS BUT SOMEHOW I BUSTED THEM I GOT SOME KICKERS NOW AND THEY SOUND NOTHING LIKE THE JBL I AM GOING TO GET ANOTHER SET CAUSE THE JBL BUMP HARD I LOVE THEM!!!!!!!!!!!! NIKKI haltom city, tx
i'm wondering why the 3 reviews above me love these so much. I think they suck. I've gone through 4 already. They keep blowing. The first two times it was because my EQ's in my car were too high, but then I turned most of them down so it was considerably quieter, but now they BOTH blew. Before just one or the other blew. They're good while they last which is why I gave them 2 stars, but they DON'T last, which is also why they got 2 stars. Tommy Denver, CO
These speakers hit very hard and are inexpensive, I have two 12" JBL GT4 1600 watts each. They are being pushed by a JBL amp 6000 watts pretty nice too. I recommend this if you want long lasting bass. Eduardo Modesto, CA
These JBL's are the best boom for your buck. I just bought another pair of these for both my cars. I have also had a pair of these since 1996 and I still use one of them in my home theater system and it still shakes the house even know i put a hole in the surround with my drill in 1998 when I was installing it in my car. These are great subs! Bryan VA
