JBL GT-BassPro12 12-Inch (300mm) Car Audio Powered Subwoofer System, black

I previously had a West Coast Customs dual 10 inch sub and amp. Had it since 2014 and recently decided to upgrade the amp with a RockFord Fosgate amp which made the subs sound better than they previously did but something was off and did not sound right to me. Decided to return the Fosgate amp and throw the subs to my local thrift store. I came upon this JBL sub while looking for a new one. I could not believe the price so I did some research on it and liked what I saw so I took a swing and bought it. Arrived in excellent condition since it was double boxed. Comes with a remote to adjust the level from your sitting position but I do not want to use it. I used the previous 4awg cable I already have installed but unfortunately the wire is to thick for the input on the amp so I cut some of the wire off to make it fit. I don't think that is the right thing to do but desperate times call for desperate measures. At first I did a sloppy job at cutting and connecting the power cables to the inputs on the amp but it got the job done. Turned the radio on and the sub turned on as well so that was a good sign. At first impressions it sounded good and was exactly what I was looking for. But I was not satisfied with the was I put the power and ground cable to the amp so I took my time and did it right to make sure no cable strands were sticking out. I lowered the level knob a little below half and set the low pass a little above 80hz. Set the high pass filter on the stereo to 90hz so the speakers play nothing below that and holy smokes!! I hit the sweet spot. The bass is so deep and powerful you can feel it in your soul. It's not thumpy or boomy which is what I wanted. It almost sounds as good as my home theater sub. It reflects perfectly off the speakers which is what you want. It should not be directional to the point that you know the bass is coming for the sub in the back. It should sound that it is coming from the speakers. Never have I bothered with JBL products but now they have my attention. Definitely worth the money if you are looking for an all in one package. Nice and compact size and definitely excellent sound quality if you take your time to adjust it.

The JBL GT-BassPro12 is a very nice all in one subwoofer. The subwoofer feels well made. Thick plastic, soft outer ring all lend to a durable feel. The metal bars over the sub look great, but are not there just for looks. These bars are strong and will protect the sub from items coming in contact with the sub. I find this particularly helpful keeping groceries in the trunk from destroying or denting my cone. The carpet is smooth and well fitted with a short nap. The amplifier is 150 watts RMS and built into the rear of the enclosure. It looks small in the photo, but remember that's a 12" sub. It is a large and heavy box. The controls are all on the rear, but a really nice touch is the remote gain. By running CAT5 cable to the front of your vehicle, you get remote control of the sub's level gain. So much more convenient than popping the trunk pulling sub forward, tweaking, then pushing back in position. You can use both line level inputs or speaker level inputs. With speaker tie in, there is an automatic on/off feature that sense when the sub should power on. This avoids the remote power on wire. I used the traditional RCA cables to bring signal to the amp. Being all in one mad for a super fast install. I highly recommend this for anyone looking to add bottom end to their audio listening experience. It will not blow the windows out of the car next to you. I was surprised by the volume and quality from only 150 watts. Great sub.

Purchased this and a Dual brand install kit. The install kit was trash. Cheap CCA wire and weak wire connectors. Its a 6 dollar copper coated aluminum kit disguised as a 30 dollar kit This JBL Harmon (Of Harman Kardon) 12" dual coil sub and 150 watt Harman amplifier is a SbS home run! (SbS - single box solution) just dont get the 29.95 Dual install kit. - total junk- Unboxing reveals a 12" tuned and ported JBL Box with sub and amp built in. Install was in 2014 Taurus Police Interceptor, installed by running RCA inputs to both rear speakers, jumpered the blue (amp on/off wire) directly to positive terminal, turned the auto turn on switch to on, ran a 4 ga power wire from batt to amp, ground strap to rear decklid Boom! Green lite came on and this setup blew us away. Crisp clear 40 to 350hz adjustable bass, line level adjust and bass boost and this setup legitimately banged pretty hard. At its price point it is a winner! Youre not gonna win competitions with it,, but as a one box solution for ANY base model that needs some serious low end boost, look no further! Its quite impressive! Make sure you have a solid direct to battery connection and a solid less than a few feet ground and youll have enough power to run it well. The killer of setups like these is clipping from poor power supply conditions - that crackle when bass hits, contrary to popular belief- isnt too much power, its too little, and that will smoke the voice coils fast. Give it clean power and signal and dont expect windshield expanding bass notes (but good solid trunk rattling bass regardless) and you will be quite happy for the price. This is my 5th install of this model, 2014 Interceptor, 2005 Savana Hi Top van, 2010 Tahoe, 2005 Tahoe and 2007 Escalade. Each and every vehicle sounds spectacular! 5 stars for sure!

Well worth the cost. This guy spits out amazing at anything above 40hz. Anything below not so much. Very awesome for metal. I put down the seats to open the truck chassis and point this guy directly towards me and it literally gives out violent back massages. Had to go a bit crazy with the deadening but it was worth it. Edm sounds great too it does low atmospheric drones very well considering the size of its port. Attaching cables to the amp is awkward and required me to solder my wires to prevent the wires from just falling out from the upside down screw lock that sucks to work with. I was working with 8 ga wire which is far too big for those screw holes. Once properly installed though not a big deal. Bass boost is a nice feature to bring out tones near the 40 hz range. A nice package that peps up regular music with enough headroom to crank it for the more aggressive or complicated stuff.

Todo bien

Superb. Design, sound, looks, everything. For that money you are really getting more than you are paying for. Just go for it blindly you won't be disappointed.

Jbl....is the best company....extreme perfomance .....powerful bass

I added this subwoofer to my stock stereo system in a 15 Subaru Impreza and I'm loving it! I just wanted to add a little thump to my stock radio and this does the job and more. The woofer provides window rattling bass and definitely gives you the vibration in your body that real bass heads crave. It takes up quite a bit of room in the trunk so make sure the dimensions work for you. This speaker will also overpower your stock speakers if turned up really high so take the time to find a level that works. I would recommend his speaker to anyone trying to spice up a stock stereo system
