    • Nice upgrade for any stock sound system. Worked perfectly in 2025 Jeep Gladiator Mojave
Style: subwoofer
This thing hits hard, plays loud and clean. Don't let the 8" size fool you. It's basically a much better version of an OEM subwoofer like on B&O systems. Will give you that rounded fullness and kick that standard factory systems are lacking. Take your time and dial the gain, boost level to blend with speakers. The result is worth it. I've been doing ICE installs for 20+ years. This is a great product. Installed in a 2025 Jeep Gladiator Mojave and upgraded all other stock speakers to JBL Club Series speakers (6.5" in kickpanels and 6.5 in overhead pod using Metra pods and adapters, 3.5" in dash). Huge difference in clarity and volume. FYI for the sub signal I tapped the front kickpanel speakers and ran the wires down the driver side to under the driver seat. I found this easier than messing with the wire loom for rear overhead pod speakers in the B pillar ... show more

    • Perfect compact size
Style: subwoofer
Love this sub. Sleek looking, compact design for small spaces with some good bass. Feels premium as JBL should. Had it for over 1 year now and no complaints. I have this in my Ford Maverick Hybrid so installing was easy because the battery is in the back seats. Just less wires to run to the front. Only ran the volume control to the front and you can hide that easy. ... show more

    • Fantastic for a small hatch back
Style: subwoofer
Review Image by Alex
Review Image by Alex
This 8inch sub and amp combo is excellent! This works great for a small hatchback with just 4 factory door speakers, this completely changes the sound of the whole system! Install was super easy, ended up mounting it in the hatch rather than under the seat. Will definitely be upgrading to some JBL door speakers soon. Another thing to note with this sub and amp, it isn’t a huge, powerful sub, it’s just enough to add clean bass to your vehicle, if you go from factory speakers to adding something like this… trust me you won’t be disappointed. The bass won’t shake you’re license plate, but it will definitely add some in a car with no sub, and factory speakers. Also sound dampening helps 100% more, and makes the bass much more powerful. In the end if you are looking for a sub that’s going to rattle your license plate off, this definitely isn’t for you. However if you want a simple upgrade from factory, this thing is great, and the user interface is super easy. All included hardware was very nice, and high quality, definitely something to expect out of a JBL product! ... show more

    • Good boom juice
Style: subwoofer
So first of all, it makes plenty of noise. I bought this because my civic had little to none on the bottom end. With the freq settings and crossover I was able to get all the sound I was missing out on the factory radio. I keep it right at the 1/8th turn setting and it’s good for me. Anything above that and it drowns out everything and tries to vibrate my mirrors off. Overall a good product and can run pretty much from a 12vdc outlet in your car. ... show more

    • Fits Under the Seat
Style: subwoofer
I know it won't fit under every seat, but it fits under the passenger front sit of my rig. I bought a new vehicle that had a garbage sound system. First thing was to rip out all the speakers and replace with new. I still wasn't satisfied with the sound. So I bought this and wired it up. That went very smoothly and the sound filled out nicely. I do suggest wiring and installing the remote volume control. When switching from say, Apple Car Play to radio the audio is not optimized for both and adjustment is needed. Radio stations use continuous look-forward equalizing boxes on their audio prior to transmission, so the bass generally picks up quite a bit when you switch to radio. Easy to adjust with the remote mounted in a convenient location. ... show more

    • Huge sound, extremely compact.
Style: subwoofer
Extremely compact and tiny. The sound is much bigger than what it is. Its not going to blow you away but will deliver the bass you need to make the songs sound full and a punch. Great buy especially for the price.

    • Not a game changer by far!!
Style: subwoofer
Only get this if your system is completely GARBAGE! Adds a little thump,but will still need to change out your door speakers to feel satisfied. It's ok.
