JBL's take on the compact sub

With cars getting smaller every year, JBL understands that the need for compact powered subs is greater than ever. Their latest BassPro SL 2 powered sub delivers impressive bass from a stealthy low-profile enclosure that'll fit under the seat in many vehicles. Its 8" shallow-profile woofer was designed especially for this compact enclosure, so you know you'll be hearing some strong bass.

JBL's take on the compact sub

125 watts + 8" sub = nice bass

The built-in Class D amplifier delivers 125 watts RMS to the sub, and you can use the low-pass filter, bass boost, and phase switch to get the best possible performance in your vehicle. The amp hardly gets warm when it's working, so you don't have to worry about installing the Bass Pro SL 2 under your seat or in some other tight space.

The Bass Pro SL 2 includes line- and speaker-level inputs with an input load switch.

Features

Enclosure & Driver: The JBL BassPro SL2 features a single 8" woofer in a compact sealed enclosure. The woofer driver features a polypropylene cone with a butyl rubber surround, mounted in a durable ABS enclosure that's compact enough for mounting under seats and in tight spaces.

Amplifier: The subwoofer enclosure is powered by a built-in 125 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 SL2 includes a pair of RCA low-level signal inputs, accepting signals from 0.05V - 2.0V. If connecting to a factory headunit or radio without pre-amp outputs, a 2-channel speaker-level input harness is included, accepting signals from 0.5V - 20V.

Audio Sense: The Audio Sense switch, when set to On, allows the BassPro SL2 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 120 Hz; the crossover slope is 12 dB/octave.

Bass Boost: The bass boost circuit provides a variable (0-9 dB) signal boost centered at 70Hz.

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.

Other Controls&Indicators:

Phase: A two position switch (0° or 180°) allows the subwoofer's phase to easily be inverted .
Level: A rotary knob adjusts the input signal level.
Input Load: Used in conjunction with the speaker-level inputs, this 2-postition switch (High/Low) can be set to provide the lowest amount of noise with a high-level input signal. Generally, this will be set to the High position for most factory radios.
Power LED: Lights to indicate unit is powered on.
Protect LED: Lights to indicate a fault or short-circuit.

Connections:

Remote Bass: RJ-25 jack for use with included remote bass level control.
Fuse: A single 15 amp ATC fuse protects the amplifier.
High Level Input: Accommodates the included 4-pin Molex high-level input harness.
Power/Ground: Three set-screw terminals provide connections for Power, Ground, and Remote In, each accepting up to 8AWG wire.

What wire harness adapter is needed for 2016 gmc sierra with bose system?

joe Dec 02, 2023

1 answer

We do not have a simple harness for adding a factory subwoofer to your vehicle. We do carry a module and harness kit that would help with the project (out of stock at the time of writing). I've linked this item below for reference: www.crutchfield.com/p_541APSGM61/item.html

zachary Dec 03, 2023 (Staff)

confused which one to choose ( JBL basspro sl2 or jbl basspro nano? Iam not a technical guy to compare number just need a high quality subwoofer compact and punchy bass for everyday use. I have purchased all the speakers for my vehicle from you guys ( camry sedan 2023 7" factory Radio. So plz help me decide . Thanks

abdalla Jun 29, 2023

The Nano is going to be about 6 inches smaller in width, the same length, and a touch thicker but about the same. The Nano draws slightly less power and has a slightly higher range for frequency response but it's going to be hardly noticeable. Really, they are so similar in specifications that the only real question you should have is size. Where do you plan on putting it? I measured the very specific spot I had to place it in my truck a few times and had trouble meeting that size constraint before finding the Nano, which is the perfect fit.

alex Jun 29, 2023

After installing each of these in very similar extended cab trucks, I recommend the SL2. My son purchased an SL2 for another truck after we discovered the improved performance of the SL2. Not that the Nano is bad, but the SL2 is better at all volume levels. Both take a little time to adjust after some days of listening at different volumes and different music. Don't forget to check ALL settings in the head unit for something that will mess with your results.

Does anyone know if this will fit under a 2016 honda fit seat?

sean Jan 31, 2023

Greetings , and thank you for your question. Unfortunately we do not measure under vehicles seating. What you would need is 3 inchers of height for the JBL BassPro SL2 to fit.

This is not weatherproof.

I have a 2019 Toyota Tacoma and have updated my head unit to Sony XAV-AX8100 which has RCA subwoofer out. Would I need to tap into the speaker wire, or can I use RCA cable for the sub?

jerry Jun 27, 2022

1 answer

Greetings Jerry, and thank you for your question. You can do either, performance wise its better to use the RCA subwoofer out from your new stereo. You can control frequencies thru the stereo then.

hogan Jun 28, 2022 (Staff)

Hi does this works with 2022 xc90 base sound system?

amit Jun 15, 2022

1 answer

This can be used in the vast majority of vehicles by tapping into the vehicles speaker wires for signal. One of our Advisors can be reached by phone (1-800-324-9695) or online chat. They should be able to help answer your question and go more in depth on your specific installation needs.

thomas Jun 15, 2022 (Staff)

I have a 2018 Crosstrek with Android Auto but no cd player, I just upgraded speakers but still need bass, should I start with head unit or would this fit that head unit with an adapter?

thomas james Apr 25, 2022

1 answer

The JBL BassPro SL 2 features a speaker level input harness you can use to tap directly into your stock wiring. We also have a car specific t-harness for your Crosstrek that would make it easier to integrate with your stock radio. We need a little more info about your Crosstrek to determine which t-harness would be best. Give us a call at 1-800-324-9695 and we'll be happy to help find the right gear!

I am not a professional experienced here but I believe you can do it as when I bought this one, I was asked to install with factory speakers or upgrade to better ones.

minirkumar Jan 10, 2022

You should be able to. Just need a sub out from your head unit and a reference line so the amp will automatically turn on.

adrian Jan 10, 2022

Can I integrate this with my 2021 Toyota 4Runner car stereo system? Is there a wiring harness kit to facilitate this?

ralph Jun 21, 2021

1 answer

This powered subwoofer can be installed into 2021 4Runners and depending on the stock system, we may have parts that plug into the stock wiring to get the audio for it. I recommend contacting an advisor by calling 1-800-324-9695 to discuss your 4Runner and get a recommendation on all the gear needed to install it

No it doesn`t come with a harness.

charlie zarate Jun 23, 2021

Yes

georg Jun 22, 2021

Mine did

jason Jun 22, 2021

It does have a speaker level input harness in the box which plugs into the amp allowing it to use speaker level inputs. We have advisors that can be reached by calling 1-800-324-9695 who can help you get wiring and connectors to connect that harness to the speaker wiring

has anyone installed this in a newer Acadia19-21 years.?..TIA for the input

larry May 11, 2021

I have a 2nd Gen tacoma (2014) double cab. It has ac/heater vents under the front seat for the back seat passengers. Can this be installed under the front seat over the vents or will this cause damage to the product?

We have not received any answers from other customers on your question. I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They should be able to help answer your question.

Can I instal the job probass sl 2 for 2019 Toyota Highlander hybrid?

kiran Mar 23, 2021

1 answer

If you are looking to put it under a seat, it should fit. I would look up the sub dimensions and measure the spots your are looking to install it. Also remember when picking a spot to install it to account for the cable lengths.

adrian Mar 23, 2021

Does this fit under the front seat of a 3rd gen Toyota Tacoma?

avery Mar 05, 2021

Is it possible to use one remote to control both of these subs? it looks like they just use a standard ethernet (RJ45) connector for the remote, so could you just use a splitter to split the signal from one remote to have control of both?

nick Feb 18, 2021

1 answer

The remote level controller cable has RJ-25 connections on each end. We have not tested a splitter to know if one controller will operate two of these subwoofers. I recommend contacting JBL's support using 800-336-4525 to check with them if it will work

jason Mar 09, 2021 (Staff)

I have little room under the seat and the unit would be quite cramped with little to no air space. Is that going to be an issue?

laverne Feb 15, 2021

2 answers

This powered subwoofer is designed to be installed in tight spaces without causing any issues and sounds like it will work under the seat in your vehicle.

jason Mar 04, 2021 (Staff)

I made a custom installation on my 2021 rav4, I made an adapter plate and installed the powered subwoofer on the rear cargo area...

miguel a. Mar 01, 2021

This looks exactly like the Infinity BassLink sm2. Are they one, and the same?

mark Jan 27, 2021

2 answers

no and be careful it doesn't fit under the mustangs seat

raymond t Jan 27, 2021

Both Harman Audio. Probably.... I'd bet they both have a bit of a house sound. Infinity tends to be a bit brighter, JBL tends to have a thicker mid-bass, though they frequently use the same components, with different crossovers after Harman/Samsung bought them. I own the JBL in an old pickup that I wanted to keep looking relatively stock, and not put much money into improving a 40-yo stereo. It's a great little sub for "fill" in the low end. Don't expect your friends to hear you a half mile away.

andrew Jan 27, 2021

Do you need an amp for this JBL Basspro SL2?

fernando Oct 26, 2020

7 answers

No...It has its own amp built in. Of course the receiver has its own amp as well. No separate amp required.

matthew Oct 26, 2020

No it has an amp installed with the sub.

jerry Oct 26, 2020

This has a built in amplifier

nathan Oct 26, 2020

raymond t Oct 26, 2020

No.

cortney Oct 26, 2020

It have a built in amp already. So no.

thanh Oct 26, 2020

It's a powered sub, so... No.

andrew Oct 26, 2020

2020 CHEVY SILVERADO 1LT TRUCK INSTALL. LOOKS LIKE I'LL NEED A WIREING HARNESS LOOP ADAPT. POWER SUPPLY KIT IS INCLUDED BUT NOTHING THAT I CAN TELL FOR COMPLETE INSTALL WITH SPECIFIC VEHICLES. ALSO IL WILL BE ADDING 2 OF THESE SO HOW DOES THAT APPLY?

josh Oct 24, 2020

1 answer

It will be easier to install two of these using a dual amp wiring kit for the power. The signal is be a different story and is dependent on the system in the vehicle, and your preferences for the sound clarity and control. I recommend contacting an advisor by calling 1-800-324-9695 to get a personal recommendation on all that installation gear

jason Nov 22, 2020 (Staff)

Is it possible to have 2 of these JBL Basspro SL2 in my 2017 Jeep Wrangler? If so, what (accessories, kits, etc.) would I need to make it work?
