About the JBL BassPro Nano

Compact bass for your compact space

Today's compact powered subwoofers have brought the pleasures of great bass to smaller spaces than ever before, but there are still places a typical compact sub won't fit. JBL's BassPro Nano gives you 100 solid watts of RMS power in a 10" x 8" x 3" enclosure that fits under almost any seat. A specially-designed shallow-profile 6"x8" woofer gives the BassPro Nano the impact of a larger speaker while saving valuable space. The die-cast anodized aluminum enclosure and metal grille protect the speaker from accidental damage.

Control over your bass

The low-pass filter, adjustable bass boost, and phase switch help you dial in your sound. Line- and speaker-level inputs with switchable load give you multiple options for wiring your system. The included wiring harness simplifies installation, and a wired remote control lets you adjust the sub's volume from the driver's seat. When you need to bring modern bass response to the cramped spaces of today's vehicles, the BassPro Nano delivers great sound in an easy-to-fit package.

Product Research


Enclosure & Driver: The JBL BassPro Nano features a single 6x8" woofer in a sealed enclosure that's compact enough for mounting under seats and in tight spaces.

Amplifier: The subwoofer enclosure is powered by a built-in 100 watt RMS Class-D amplifier. Class-D operation means the amp runs cooler and draws less current from the vehicle's electrical system.

High/Low Inputs: The BassPro Nano includes a pair of RCA low-level signal inputs, accepting signals from 0.1V - 4.0V. If connecting to a factory headunit or radio without pre-amp outputs, 2-channel speaker-level input wiring is included, accepting signals from 0.25V - 10V.

Audio Sense: The Auto Turn-On button, when set to On, allows the BassPro Nano to power on when it senses voltage on the speaker-level inputs, eliminating the need for connecting a remote turn-on wire.

Crossover: The amplifier's low-pass crossover point is continuously variable from 50 to 150 Hz; the crossover slope is 12 dB/octave.

Bass Boost: The bass boost circuit provides a variable (0-12dB) signal boost centered at 50Hz.

Remote Level Control: A remote level control is provided, that can be mounted under a dash or console for easy adjustment of the bass level from the driver's location. The remote level control includes a 16.5' remote cable terminated in RJ-25 connectors on both ends.

Mounting: The JBL BassPro Nano includes 4 mounting plates and hardware for installing the subwoofer under seats, rear truck cabs, trunks, or any location where space is tight.

Additional Controls&Indicators:

  • Phase: A push-button switch (0° or 180°) allows the subwoofer's phase to easily be inverted .
  • Gain: A rotary knob adjusts the input signal level.
  • Power LED: Lights to indicate unit is powered on.
  • Protect LED: Lights to indicate a fault or short-circuit.


  • Remote Bass: RJ-25 jack for use with included remote bass level control.
  • Fuse: A single 15 amp ATC fuse protects the amplifier.
  • Input Harness: A 12", 10-pin input harness includes: Power and Ground (12 AWG), a Remote Input wire, and Left&Right High Level Input wires.

Customer Q&A

25 questions already asked

I have a 1994 Mazda B2300, standard cab. (It's essentially a rebadged 1994 ranger.) I'm definitely going down the powered sub route, as I have no room whatsoever in the cab for a normal sized sub. I'd love to put one under the drivers seat, with another under the passenger, I want It to be nice to look at, and permanent. Would that be too much bass for a small truck? Not enough?
[ Kyle  Nov 17, 2022 ]
3 answers
There is a wired remote volume control that comes with the unit, so I would not be worried about too much bass. Mine is actually in a golf cart, under the seat, so I can't speak to how it sounds in an enclosed cab. The rest of my system is 2ea. 6" JBL speakers driven by an amp. This fills out the low end nicely and I love it, but it does not really "bump"... I am in a totally open vehicle though, so no telling if it would have more punch inside the cab if that's what you're looking for...
[ Tyler  Nov 17, 2022 ]
I have installed this same JBL unit in a Honda Civic Hatchback (under the passenger seat), an Audi A4 (in the trunk) and have a new one in the box waiting to go into a Subaru Forester. These units really help improve the overall sound of stock systems. In my experience the bass volume can be turned up to overpower the rest of the system, so I would suggest starting with one. If you find you want a second unit it would be really easy to link them together.
[ Gary  Nov 17, 2022 ]
It will depend on how much you want to rattle things. Put one in an extended cab GMC and it works well, but not overpowering. Not using high volume levels, because I want to keep my hearing. You will have plenty if you use 2 units, IMO.

would this guy work in a 2016 Polaris General 1000 with the MTX soundbar?
[ BRIAN  Nov 11, 2022 ]
1 answer
This JBL has no marine rating sadly Brian, this would not be a great choice on your 2016 Polaris General 1000 as it may not hold up to the rigors of offroad use. We do offer an SSV Works 170-GN-UD10U subwoofer enclosure that will fit your General and handle not only the SSV works 10" sub but many other 10" marine rated subwoofers. If you are looking for a marine rated all-in-one then scope out the Bazooka MBTA10100 in the second link below. If you can fit this in, it performs similar to the JBL sub but is marine rated for water resistance and shockproof!

Will this fit under the seat of a 2017 wrx?
[ JEFFREY  Oct 04, 2022 ]
1 answer
Greetings Jeffrey, and thank you for your question. We unfortunately do not measure under vehicle seating. The JBL Nano is a tad less than 3 inches tall. It is designed to fit under most vehicles seats, but you might wat to take a measurement under you seat first. There is not much of anything that would be less tall than the Nano.

You do not have to use the screws. You can mount using velcro if you prefer as long as it is secure and has good ventilation.

My radio has only one sub out and i see this has 2 in. Would a rca to y cable work on this?
[ Gerrith  Feb 23, 2022 ]
3 answers
[ Mark  Feb 23, 2022 ]
No need. Just run a single cable to either of the inputs.
[ Nicole  Feb 23, 2022 ]
This is a mono sub, so I am pretty sure its just combining the two inputs anyway, so you should be ok just plugging into one of the channels on the sub. While I dont THINK there would be a benefit to using the rca splitter, I also dont think it would hurt anything.

Not sure specifically for that car. I put it into a 2005 Honda Accord LX under the drivers seat and fit perfectly.
[ ADAM  Jan 06, 2022 ]
Could this be used in a home theater system with a receiver instead of a car?
[ Tom  Dec 14, 2021 ]
5 answers
Could be, but you will have to have a good 12 volt DC power supply.
[ Alan  Dec 15, 2021 ]
The BassPro Nano is powered by 12 volts DC. Your home theater will be using AC (120 volts if in USA) so the short answer would be no.
[ BRIAN  Dec 14, 2021 ]
No, it's powered by 12V dc. Home theater equipment is powered by120V ac. You could purchase an inverter, but the sub would amplify the "dirty" noise of the inverter. This would not be a good choice.
[ BRET  Dec 14, 2021 ]
It would not be practical. But if you can set up a 12volt power with enough amps it should work.
[ Binh  Dec 14, 2021 ]
It works great for a small space like a car interior, but it would be undesized for a home theater environment. In addition, it requires a 12 volt DC power supply.

[ Paul  Oct 25, 2021 ]  Staff
I'm just making sure I understand the Bass Remote Control function when the bass remote is disconnected. I tried the unit with and without the bass remote connected. As far as I can tell, the BassPro Nano reverts to "MAX" when the remote is disconnected. As my Alpine Head Unit has sub woofer outputs, I'll just control the Nano via the Head Unit. There is no documentation in the owners manual with respect to this issue. I presume no harm will occur to the unit because of this?

How would you recommend hooking this up to a 2021 4Runner with the non-JBL system?
[ John  Dec 03, 2020 ]
5 answers
I got this for my Honda S2000 back in April 2020. This is not a plug and play component. You will have to run 12 volt power from the battery with an in line fuse, as well as splicing into your factory stereo to get the signal wire hooked up. It does not come with the fuse or wiring so I had to buy that separately from the autoparts store. I am a pretty seasoned DIY'er, got an alarm system at the same time because someone broke into my car, installed everything myself, but sounds like you need to take it to a professional installer since you are asking this question.
[ CALVIN  Dec 05, 2020 ]
Yes this makes better base but not too hard.
[ Jannette  Dec 05, 2020 ]

Can I use an 8 gauge amp wiring kit? Mainly is it safe to splice 8 gauge power to the 14 gauge wire on the Nano's loom? What's the best way to step between the two wires or Is it better to use a smaller wire?
[ Chris  Oct 01, 2020 ]
2 answers
No reason you cant go from 8 ga to 14ga like that, Actually the more, and longer run of thicker ga cable you can use the better. You will have less voltage drop that way, not that the Nano is a high power draw though. You just need a way to physically connect the 8ga to the 14ga wire. You can solder it. Or maybe use a small distribution block.
[ John  Oct 01, 2020 ]
Sure you can. Just take care and do a good job on your splice and insure that you put a fuse on the positive side of the circuit close to your battery. Try to keep power wires away from speaker wiring due to the RF from the power wires. If you run power wires next to speaker wiring you could end up with a whine that you can hear through your speakers that will change pitch with the RPM of the engine. Hope this helps
[ SHANE  Oct 01, 2020 ]
How do you power this, what gauge do you connect to the harness?

Hope to answer your question; On my honda truck this sub was installed by someone I know for while, because I was afraid to burn it, the fairest they explain to me, was connected on the wiring from the speakers on the head unit, Sorry for don't help on this matter,
[ Oscar  Jul 07, 2020 ]
I recently installed a pioneer head unit, door speakers, dash speaker, and this subwoofer. First and foremost, I hope you didn't fall prey to the quick connect RCA plugs on the subwoofer and / or the head unit. They wont power the speakers. Hardwire everything. In this case, run the red positive wire to the battery. Run the black wire to a bolt to ground it. Run the volume / on / off cable to wherever you want to quickly adjust it. For me, I ran the speaker wires from the subwoofer to the head unit and connected it with the rear left an right speakers. That may not be the best speakers to add it to, but it worked for me and sounds very good. Hope this helps.
[ Tj  Jul 06, 2020 ]
Is your factory amp able to push the power those infinity door speakers need? If not I would recommend doing a duel amp wiring kit and running power for both a 4 channel amp and this sub. The basspro nano is a very good system, but is only good if it is in the main cabin under a seat. It will have a very hard time going from the trunk all the way to the driver seat. It is not powerful enough for that.
[ JOHN  Jul 06, 2020 ]
Just follow up the manufacturer installation directions. Set up is very easy. Also, don't forget Crutchfield'sTech support. They can help you with any questions 24/7. Hope this helps!
[ Vladimir  Jul 06, 2020 ]
I have a 2018 GMC Sierra that has cables to connect a sub under the seat, is there a kit that can be used to connect this subwoofer at this same location? The wiring is from the factory and designed to connect a kicker amp and subwoofer that is sold by GMC.
[ Victor  Jun 19, 2020 ]

The JBL basspro nano comes with line and speakers level inputs you probably can use the factory wires for input There should be a power,ground and remote wire from the factory since it was designed to connect an amp and subwoofer

I have a 2006 Jeep Wrangler with center console sub. Can I hook this up off of the existing sub and have both or is it one or the other?
[ Glenn  Jun 16, 2020 ]
2 answers
If the exiting sub is powered then no you can't take that amp powered signal. But you can take the signal pre amp and use that for this sub to run both. Usually if a signal is split like that it gets a little weaker. The JBL has adjustable gain so you can even out with the existing sub or not depending on the two subs sizes you can cover more Hz range.
[ Binh  Jun 16, 2020 ]
Not sure if this will ensure success for you, but I did something similar with the small "sub woofer" in the center console of my 1997 Lexus LX450 (Land Cruiser). It has a 4" factory-mounted sub in center console and I was able to fit the BassPro Nano in the center console and still use the existing factory sub as well. However, that required me to stick with the factory amp, which I will likely be ditching in favor of a more powerful aftermarket amp. Anyway, the JBL BassPro Nano is plenty powerful enough for my needs, so I won't mind losing the small factory sub when I upgrade the amp. I am very happy with the JBL! It really brought the system to another level.

I had the same question for my 1999 Boxster. I installed one behind passenger seat, and I would like to put another behind the driver's. I think that you could do it by using a phone line splitter after the wired volume control. This would send the same level to both subs, but you could adjust a bit with the gain in each. I haven't tried this, but I think it could work. Any thoughts?
[ Robert  Apr 20, 2021 ]
There is a wired volume control that plugs into amp. It cannot control any other sub. You would need an external control before the audio is split to run more than one sub.
