JBL GTO804 (Open Box)

Great Subwoofer

I run 2 of these in a .6 cubic foot vented box, and all I can say is perfect. The highs are unbelievable for subwoofers, and the lows aren't too shabby either. Still shakes the car at 30hz frequencies in the vented box. I love these little things.

awsome sub woofer!!!

For an eight inch subwoofer, this thing thumps...Great subwoofer at a great value...

Good woofer

Packs a punch for a 8 inch woofer. Like it alot especially for the price. Can't beat it

Decent little subs

For the price, they're excellent. I tossed two of these into a pair of ported boxes to put under the rear seats of my friends truck and they rock right along. They're not gonna be ear bleeding and bowel movingly loud, just nice and subtle with enough power to shake the hairs on your head if you want. I'd recommend sticking them in sealed boxes rather than ported ones but i'm more of a SQ guy, not SPL.

Can't really go wrong with them.

Jbl gt804

Excellent value and good bump. Replaced stock driver in Bazooka with this. Much better.

great

they are cheep and under rated with great sensitivity for a hi power sub you cant go wrong i put one in mt work truck and its has all most the same out put ass the 2 10s i have in my car with 1/2 the power very happy with this sub

Another great JBL product

I was very satisfied with this sub. I used it for a rear-deck replacement sub, so it was in an infinite baffle enclosure. After sound dampening the rear deck this sub performs beautifully. Because the resonance frequency of this sub is so low you almost have to use some kind of High Pass Filter around 30 or 28Hz, but because of this low resonance it produces low frequencies very easily. In my experience this sub will handle more power than it is rated to handle and has held up well to my use. It should perform very well (and probably better) in a box. Overall, to be only an 8 inch sub, it performs and sounds like a 12 inch or better. I am extremely satisfied.

Very pleased with the output of this beast!

I have always been into car audio but since getting married, I had to put all that stuff behind me until I realized how much I missed it. I have an Acura TSX with the stock premium sound system, but it was missing that thump that I was so used to. I decided on an 8" because I don't want to lose my trunk space. The JBL was the best bang for the buck. Out of the box, you can tell this was going to be awesome. It is heavy and worth its price in just the weight of the magnet. Still not sure why they call it a shallow mount subwoofer. I placed it in a small sealed enclosure (0.35 cubic feet) stuffed with polyfil and I paired it with the JBL GTO501EZ (amazing amplifier!!!!) into my stock system. This sounds great!!!!!. Though it took a bit of effort to tune in the amp (gain/bass boost) to my liking, I am very pleased. The only problem I have is that I can't keep the mesh subwoofer grill (bought separately) on it due to its excursion (hits the grill cover). I have owned almost all size of subs in my days and usually stuck with JL audio and Polk but this JBL combo is one of the best for the price. I had previously had a JL audio 8W3V3 in my old BMW X5 and this JBL sounds way better and louder but to be fair, it was a different system setup and an open trunk space as compared to the TSX. This JBL sub fills the car with huge bass when I need it without having to let the whole world I have it installed. Great buy and great service from Sonic!

it bumps!

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!

Great sound

These subs sound amazing. Never doubted from the moment purchased that they wouldn't, being a JBL product. The sound is crystal clear and well worth the price. Highly recommend these and any JBL speakers for that matter!!
