Sound good for the size.

Installed on a 1999 Honda Accord LX sedan under front passenger seat. So far sounds fair considering it's an 8 inch subwoofer ??. Still need to do final adjustments.

final review pending

This is a review of the product, having very little to do with Crutchfield service. Hooked up the speaker and it was defective, no power no nothing. The folks at Crutchfield have shipped a replacement quickly and on their dime, a stand up outfit, as always. Will update after installation.

Sounds great

Good quality, compact, but hits pretty deep for a powered sub with only 125W RMS. Alot more than I expected.

Thump and Rumble

Impressive Product! Really fills in the bottom end well and can punch pretty hard for its power level. Can't beat the form factor, got it velcro'd to the rear carpet and held down by the seat cushion in the stowed position in my Chevy Spark. Couldn't be happier with the sound; clean, smooth, and faithful after just 10 min of tweaking by a complete novice.

Phenomenal sound quality, and the fact that it fits practically anywhere in the car without taking up too much space is amazing. Fits under the driver seat on the 2019 Subaru Impreza sedan perfectly!

Compact, powerful, and good looking!

I bought the JBL BassPro SL 2 because I wanted to round out my Corvette C4 sound system. I have a Focal speaker system driven by an Alpine amp and a Retro Sound head unit. The head unit had RCA Bass L/R outputs, and that matched the JBL inputs. I had gone to a local sound shop that wanted $3800.00 to add a custom Bass system. That kind of money is destined for other mods. I was only interested in adding the bass frequencies to my set up. With limited space, the JBL gives me the bass sound, and a fair amount of "Punch" when I turn up the volume in less than 1 cubic foot of space. It looks sharp, and when I do properly mount it, it will be a powerful, but subtle addition to my interior. Finally, the small remote Bass control knob is a must as each song on my playlist has different recording levels and quality. You can fine tune the music without leaving the driver's seat.

Great when it comes on but Issues cutting it off

It was Great when it worked.. Only real issue I was having was the Unit comes on with the Car Audio System when it senses sound as it is supposed too but it would not Cut Off even after shutting down my vehicle unless I cut it off manually but who wants to keep doing that. I was worried if I would forget to cut it off manually one day it would Drain my battery and didn't want to take that chance So I sent it Back.

Works great for replacing factory 1st gen Honda Ridgeline subwoofer

I put a new head unit into my 2008 Honda Ridgeline, and found out that the factory subwoofer mounted behind the rear seats does not have its own amp, and runs off of the factory radio. Rather than trying to repower the factory sub, I went with this route and completely replaced it by screwing this unit into a piece of plywood that I had cut so it could bolt into the same spot. After replacing all the trim behind the rear seat, it looks totally factory and still has that nice little punch that the stock system had. Would definitely recommend for similar situations!

Thanks for the feedback, Clarence. We're sorry that your experience with this installation wasn't better. One of our Tech Support Advisors, Chibi, actually helped diagnose that it could be a better idea to run a remote turn-on lead and RCA connections for this powered subwoofer to the aftermarket radio that Clarence has. This actually is a more reliable way to test the subwoofer power off when the radio turns off, instead of using audio sensing. However, Chibi did not know what aftermarket radio this customer has, so she could help with the wiring for this remote turn-on lead. This customer also declined this wiring advice at the time, although he plans on doing more testing to solve this issue.

I replaced what was called a poor excuse for a subwoofer with the JBL bass Pro SL two in our RV and the difference was night and day as to sound quality and base reproduction in such a small package. If space is an issue and you're looking to add a little thump to an existing system, I would recommend this compact subwoofer.

perfect upgrade !!

I was looking to upgrade my under seat subwoofer because i was using the jbl basspro nano and just didn't like the sound it was putting out, too much rattling, hardly any bass whatsoever, so i opted for the jbl basspro SL2, man talk about night and day, this was the exact opposite of the other one, very nice bass, just goes perfectly with the pioneer stereo, had it professionally installed, by the way this was installed way better than the previous one was, the volume control allows me to add or delete the amount of bass I want, another plus, something I also didn't have with the previous one, 5 stars all around !!

Has great bass. Not great if you mount in the truck. The amplifier portion of this unit has limited adjust ability. Wish I had gone with a different sub and amp.

AWSOME

2014 Toyota Tacoma 4 door. Was looking for something to give me some extra bass without breaking the bank and going all out with amps and subs. Put sound deadening material along rear of cab. Mounted sub in the storage bin behind rear seat instead of under seat. Stopped at local install shop and had them do all adjustments to head unit and sub. Just so its right. Have a pioneer head unit and rockford Fosgate components in doors. May upgrade door speakers soon. I'm not rattling peoples windows, but the extra bass and everything set right. It sounds GREAT. I'm very happy with the Basspro SL2. My wife even enjoys hearing the extra bass and better sound. She never goes above 5 on the volume. She doesn't like loud music. From heavy metal to Buble' to country. Sounds great. Would recommend to a friend. The people at Crutchfield were very helpful and knowledgeable.

2017 F150 Super Crew

Installed behind rear seat in 2017 F150 super crew. Fit great and easy hookup. Ran power and ground under floor trim on pass side. Speaker and remote wires on drivers side. Sound good and really fills in factory speakers head unit. Little kick but definitely not same as 10/12 inch sub. It works perfect for me.

Fills in the low end of the audio spectrum

I just got this working today in my 2007 Toyota Tacoma full sized cab. It wouldn't fit under the passenger seat and at the same time adjust the seat all the way back as my wife needs it to be, so I mounted it behind the drivers side rear seat. It wasn't a bad job running wire from there to the head unit, and once powered up it definitely filled in the lower octaves with power to spare. It's easy to overdo it on the bass, so I adjusted it to just be noticed, not over the top. I'm pleased with this purchase.

Great sounding sub

I absolutely love this powered sub. I have a 2017 Nissan Titan crew cab. This unit fits nice under the seat. The wiring was straight forward and after tuning it through my Alpine, it hits and hits hard. Matter of fact I have to turn it down on most songs. You can set it to give you just enough bass to round out your door speakers or crank it up.

JBL BassPro SL 2

Needed something with a small footprint to fit under my backseat. Produces just enough deep tone and punch to balance out the rest of the stereo system. Definitely recommend this for other pickup truck owners with limited space. It will not give you strong low deep bass so if that is what you are looking for you will be disappointed.

So I'm disappointed in the richness of the bass this amplified sub puts out. In other words it is very lacking. I am currently running it in a 2020 Bolt, and the stock non Bose speakers put out the same amount of Bass this unit does. I am running JBL 10" subs in all my other vehicles and the sound is crisp and the subs hit. If you are looking to add a little more bass to your car this unit will do it with the key word being "little". I tried to give it time 6+ months and still want more. The directions and wire schematic from Crutchfield were spot on and the unit was extremely easy to install. I can't fault Crutchfield for this, it is just a lesson learned and hopefully someone will read this before being disappointed. Plan on getting something new shortly.

XL for adding some low end!

Picked up this guy to supplement the low end in a '21 Kona with the upgraded stereo that already included an 8" sub - albeit weakly powered from the installed 45W x 7 Clarion amp under the passenger seat. Rigged this up under the driver's seat, mostly due to a lack of other options, but I found that the ability to easily adjust the settings was a plus. Bottom line, sounds leagues better than the installed sub; the power is more than sufficient but I find that the shallow throw of the sub sometimes doesn't allow it to flesh out the bass and it gets a tad "farty", for lack of a better term. Some songs sound far better than others (mostly hard rock/metal) and I've found a general sweet spot with the crossover, but tweaking continues. A new inline EQ may be in my future. All in all a great improvement and an easy install to recommend - especially for the $179 deal I got! Thanks Crutchfield!

Lots of bass in a little package

Great product! I have this installed in my 2011 Ford Ranger with some amplified Rockford Fosgate 6x8 speakers and it perfectly rounds out the sound. I am very surprised with the amount of bass that such a thin 8" subwoofer can produce. I would highly recommend this to anyone who wants more bass in their vehicle without installing large subwoofer boxes. The product also comes with a wired remote to control the amount of bass which can be easily installed.

Still to bulky to fit

Too big and too thick to fit under the seats of a 3000GT. Needs to have less length and about 1" less in thickness.

I was very pleased when I fired this sub up for the first time. The amount of bass out of this compact package was amazing. I installed this in my 1970 Pontiac to fill in the lows that my two Kenwood 4 x 10s were lacking and this accomplished that and then some. If you are looking for a compact sub to complete your sound system I would definitely recommend it.

When you want just a little more bass.

This compact powered subwoofer is perfect for someone who wants a little more bass and doesn't want to spend a lot of time or money for a professional installation of giant subwoofers for monster bass. I highly recommend this JBL BassPro SL2!

Bass plus compactness

Love this Bass Speaker for the compactness and the built in amp. But one of the best things is that it works with the JBL speakers that I put in my doors in January so everything works as one unit of sound.

Happy with the sound that this 8" sub provides. Customer service answered all my questions. Very easy to install in my 2019 Subaru Forester. Didn't have to remove the head unit at all. Everything is factory except I installed new dashboard speakers to the 3-1/2 kicker. The car wasn't equipped with dash speakers originally but the harness were there. Made all my speaker connections there for the powered subwoofer. So I didn't have to take apart the car to install it. The only problem I had which gives it a 4star is the 24volt + and - plug doesn't snap into the amp. Probably a factory defect that I will have Crutchfield take care of.

Far Better than Expected!

I was hoping this would fill in the low stuff. I was not disappointed. This unit fits under the passenger seat of my 2019 Ford Ranger Super Crew. It is way more than adequate. Puts out more bass than it needs to for this size of a cabin. There are several tuning adjustments to make but once they are right it really adds the bass punch the system lacks. It does come with a wired remote. In my truck the adjustment is less than half way up and the bass is clean and tight and the way it should sound. I could not be happier with this unit.

Installed on the rear tailgate of a Wrangler, I wasnt expecting much, but I was surprised at how good it sounded. Install was easy, the only reason im droppong 1 star is something small like this should come with the harness.

JBL BassPro SL 2

Just what our Challenger needed. Fits nicely under the front passenger seat of a 2019 Challenger and provides the bass the stock stereo omits. Using an Audio Control 2Ci Pro to get a signal from the rear deck speakers and using the main speaker RCA outlet to drive the rear deck 6.5 JBL speakers with a small Kenwood amp. Makes the system sound really nice. Tried the set up with the Audio Control 2Ci, but the factory amp would cut the speaker signal if it didn't sense a speaker resistance. The 2CI Pro allowed for a selectable resistance to trick the stock head unit/amp to send the Audio Control a speaker signal

I love this sub! It Fits under the passenger seat of my 2017 Honda Civic, I don't know how it would work out in a big truck but in this little car it is the perfect amount of bass. It truly surprised me! I have the 8" , well worth it if you do not have room for a big sub box! Also, you do not have to wire it to an accessory for it to turn on, it has a sensor that senses when the power goes to the speakers and that turns it on ..

Perfect for small coupes

90's Honda Civic - Stock Honda (Alpine) radios from the 90's at some point quit working, so I recently replaced the stock receiver with the Sony MEX-N5300BT and Sony XMS400D mini amp, and Kicker speakers. That's a nice, inexpensive package, but the bass really lacks. Added the JBL BassPro SL2, and boom! Perfect match. The total package with the sub sounds about like a premium stock stereo set up in new cars. Total cost was about $500 to bring my little commuter car stereo back to life, and the JBL sub was the icing on the cake. The adjustable 40Hz boost is just about right for trunk mount. The remote adjust on the sub is a must. Different music genres require widely different settings for the sweet spot, and adjusting on the fly really helps. It wouldn't quite fit under the seat, but that's because I put Dynamat and mass loaded vinyl on the floor. I tried it behind the seat and in the trunk; advantage in the cabin, but the trunk is fine. If it didn't require pulling out the interior again and removing the vinyl, I would probably put it under the driver's seat. Yes - I recommend this for small coupes/sedans. It's just enough bass to get the job done. It's not enough bass to vibrate the hairs on your head :)

Great for a car.

Does exactly what it is supposed to. This is not a window-thumping bass. It is meant to round out and fill-in the lows of your favorite music in a compact form, typically installed under a seat. This is not suitable for your trunk. Not sure if it would be as impressive in a large truck either. But in a car... wow. I have a stock stereo in my 2019 Mazda 6 and this made a huge difference. It does add a very nice kick. Well worth it for what I want and I would buy it again for my next vehicle. If you want much more than I describe, go for a bulky trunk model. In short, 5 stars in this context.
