Review: IMPRESSIVE 8" - So I have had my 8" JBL GTO804 running off a Rockford Fosgate P2.200 bridged 4ohms @ 200 watts RMS for about 2 months now. This system is not in my car, its for my bedroom. I have the amp running off a Rosewill PSU, paired with Klipsch KG4.2 running off a good ol' Yamaha receiver. I built my own box for this sub, not using the recommended ported enclosure. I designed mine using the 12volt.com subwoofer enclosure/port calculator. I have my enclosure tuned @ 35hz with .66 cubic feet of volume (including port/sub displacement). This sub in this box sounds amazing, great for all types of music, I mainly listen to dubstep, rap, R&B and pop. Very good sound quality from such a small sub. This sub in my enclosure moves quite a bit of air. Its got a 2" x 10" port. I threw a bag at the port while playing Bass Ballin - Bass Mekanik and the bag just stayed floating around in the port. For the price I don't think you can find a better 8" subwoofer. My friends got a Rockford Fosgate P1-2x12 and I could say this 8" is comparable to one of his 12's. Great hard hitting subwoofer, very clean, great SQ and efficiency (you don't need a lot of power to get this little 8 loud). One thing i was surprised at was that this has 11.5mm of Xmax (excursion) this is more than a Rockford Fosgate P1 12 (new model). The RF P1 12 has 9.4mm. That's embarrassing. Overall, I would highly recommend this subwoofer to anyone especially if you are tight on space. Not only is this subwoofer compact, but it can get pretty loud and sustain SQ!! Mine never distorts and i do crank it... trust me. Gets really low too ! AMAZING 8!! I will be saying good bye to this jbl gto804 in January 2013 though... I have pre-ordered the Sundown Audio E8v3, will be selling the JBL to my friend cause hes going to put 2 of these ported in his Millenia. GREAT SUB! SIZE DOESNT MATTER LOL. Just buy it !
Review: Best 8" sub on the market! - I used this sub to replace the factory 6.5" subwoofer in my Explorer and all I've got to say is WOW! I've installed and listened to dozens of different subs in countless vehicles and enclosures and this one takes the mighty-mouse award. It easily handles the 200 watts RMS that I'm dishing to it with and MTX amplifier and comes begging for more. The factory enclosure that I have it in is about .35 ft^3 net airspace so it is perfect for a sealed enclosure for this driver. I debated between this JBL sub and it's cousin, the Infinity Reference 8; I ended up getting both, but the JBL won simply because it had a slightly reduced depth so it fit perfectly in my factory enclosure after I enlarged the mounting hole and fabricated a mounting ring. It digs pretty dang low (easily hits 30 hz before any significant attenuation), especially for an 8. But it is also very musical and has good transient response with a good deal of kick. It's neither boomy or too punchy, but a very good blend for anything from Beastie Boys to Fallout Boy. If you know you want an 8, I'd get this or the Infinity. Their specs are almost identical and they both sound great, but this one has a unique basket design that allows the sub to fit in shallower enclosures. I am super impressed with the clarity, kick, and shear sound pressure levels this sub is cable of it. It has pretty good excursion so it will start bouncing with enough wattage. if you're on the fence - buy it! You won't regret it!

## Questions & Answers

**Q: Will this sub fit in door of 2007 mustang gt. It has factory 8inch subs already want to up grade**
A: A check of the mounting depth shows that this sub needs 4-7/8".  I have no idea what the depth of your door is but it would be a tough fit I'm guessing. You'll need to get your tape measure out and see what the available depth is.  Be sure to check this with the window down.  Worst case scenario is the some sort of spacer will be needed.  You could relocate the sub somewhere else in the car.  Low Bass is none directional.  Additional info on the JBL sub can be found here:  http://www.jbl.com/estore/jbl/us/products/GTO804/GTO804_JBL_US

**Q: what is the mounting depth of the pioneer ts-w260d4 10" sub**
A: From Pioneer's website: Mounting Depth: 5-1/2http://www.pioneerelectronics.com/PUSA/Car/Subwoofers/Champion+Series/TS-W260D4

**Q: what cubic feet does jbl recommend for each gto804 in a sealed box?**
A: This question might be outdated for us to answer for you. Please let us know if you have any further questions.

**Q: What size box and vented or sealed.**
A: The hole for the box has to be 12 in. But the box size actually depends on how much room u have in the vehicle. Also if u have room the bigger box will have more room to vibrate and will have louder sound. And for sealed or vented it all depends on the type of sound quality. The vented will give you a more louder and thunderous hit while the sealed will be quieter but it wil be more cleaner and goes with the music better. I prefer vented but i prefer the louder noise hope i helped.

### ⭐ Crap company
*by A***R on February 4, 2026*
