Solid build, well packaged and great price for what it is. I was shocked by hard this thing hits. Easily vibrates all the mirrors with deep, hard-hitting bass. It was all my mediocre factory system needed.

This thing is an awesome all in one powered sub for my Nissan Sentra! It’s a sedan so this sub will be more than enough but I can’t speak on other car form factors. Hooked it up to the kicker 8 gauge wiring system I previously installed In my vehicle and it worked perfectly! Also comes with basic tuning instructions and a bass knob to get the most out of the system! The wiring kit included will probably work as well but 4 gauge will be a bit thick to actually connect to the sub. Overall very happy and glad I can call my car the block rocker 9000 now! XD

It won’t disappoint!!! It’s super punchy and great quality. Love it’s built in amplifier and enclosure so save a lot of money. I also have a stock Bose system in my hatchback so I just needed something to bring it over the top because my sound system was already great! But is definitely sounded better than expected with my stock Bose system. Let’s just say the rain pauses before touching my car😂! I also bought Velcro straps on Amazon extreme strength max hold 15lb but the sub doesn’t move at all and probably wouldn’t move without the straps because the sub is heavy but just got it for precaution and I bought a grill on Amazon to for protection which I recommend

Despite the poor packaging, sending in original box without any extra care taken and a damaged box, the item was in pristine condition. Many reviews say this sub doesn't hit hard enough. To those people I say you need to learn how to set the amp controls properly. This little sub pounds hard when dialed in correctly between the amp settings and deck settings id easily say this sub hits harder than many 500 watt setups from most high end manufacturers. You can't beat it for the price.

This JBL sub is an awesome unit. Small enough that it doesn't eat my whole cargo space and sounds absolutely fantastic. Only drawback was no grill to protect the speaker but that was easily fixed with a 10 dollar grill.

Got this for my son for Christmas. I have to say I was really impressed! It’s a real upgrade from the stock system. It’s hard to believe that just adding a sub can make such a difference! BTW he loves it too! Yes it will not make it sound like a $10,000 system but it only cost $240 worth every penny!

Wires are way too thick, I recommend 8 not 4. Has very little bass for how big it is, my stock bass is just as much, it’s about $150 too expensive because of how lowballed it is. This thing is trash. Way too expensive for how loud it is. I mean my neighbors can occasionally hear it but that’s because it’s too quiet here. Do not buy, it will not shake and rattle you around, it will just make noise.

Sounds great! 4 gauge power wire that came combined is a little much. 6 or 8 gauge would probably work and be easier to run. Love the auto on feature. No need to run remote wire. Bass? Oh yeah, Wow!
