JL Audio RBC-1 Bass Knob - Customer Ratings & Reviews

perfect

Works great if some songs bass is just to overpowering for the music by allowing the alteration of the bass boost

Great Controller!

I'm currently using this on my 500/1 and it works awesome. For those who don't know, this does not work in conjunction with the settings on the amp. It will over-ride any setting you've set on the amp and lets you control the bass boost yourself. Great for the little extra boost you may want sometimes when jamming out. Highly recommend for any JL amp compatible!!!

Must have

This item is a must have for any sup amp that you buy from jl. It makes tuning the amp quicker and allows for great control once your install is complete.

Quality as always

JL audio has never let me down when it comes to their product quality.

JL AUDIO BASS KNOB RBC1

Worked nicely!

A must have!!!!!

I have always been a big fan of the bass knobs it's so nice being able to turn your amp up and down from the drivers seat, and they are very easy to install.

Simple to use. And a must for jl amps

I would recommend this for anyone who owns a comparable jl audio amp. Simple to install and makes adjusting the bass as simple as a turn of a dial.

Good Product

I really like this for the convenience. I wish that it was a gain control instead. But I still love it. No digging through menus in your deck just turn the dial.

JL Audio RBC-1

This is a great product. It does exactly what is says it will do... Allow remote control of the gain on a JL Audio amplifier. As you might suspect, thieves know to look for audio equipment like this to determine if there is anything worth investigating in the back of your suv or trunk. I'd suggest installing it in a place where it cannot be seen from outside of your vehicle. I know this through experience. Luckily, my trunk cannot be accessed without a key or if the vehicle in a off state.

jl audio rbc-1

we are talking about jl audio, simply the best, great product. And thanks to sonic electronix, my favorite place to buy online. I had gotten before a jl audio amp (500/1) from sonic electronix and my transactions were very smooth and very very on time. great prices so far 100% recommendable.

Awesome

Very good switch. My amp didn't come with one. This worked perfect. Got the job done. The only hard part was to mounting it because it did not come with a mount, like my previous controller

RBC-1

Works good with my JL 500/1v2.

These work on JL A-series amps as well.

if you dont have it buy it now.they work on jl A-series amps too.

gotta have one

I got this product to go along with the JL 500/1 amp I also got its great to have so you can adjust the bass easier than going into the receiver and finding the subwoofer output

good value

This is one of those products that you would have to decide if you need it. Myself I do need it because I have two small kids. with me running close to 5000 watts i need to be able to control those W7 12s. So get the JL RBC-1 its a good buy. Also if you hide it like a did you can foll your friends and make them thikn you just have two 8 in drivers lol.

Nothing special

This is good to have along with your Slash amplifier, but it is not really needed IMO. I prefer using a bass level control knob because I usually always have the bass boost all the way up. I couldn't find a way to install this using the screw provided so I just glued it on to the surface of my glove box( didn't want to make a hole).

If you're a JL fanatic and want to have the whole package with your amp, sure go ahead a buy it.

JL Audio RBC-1 Bass Knob

Works great and comes in real handy for a quick adjustment between songs. Paired this with a jl audio mx600/3.

Does the job

Easy install. Does what it says it will do. Easy, on the fly adjustments to your sub with the twist of a knob.

This bass knob is compact has a long enough wire to set my amp in the back and reach my dash with wire to spare .Very pleased with the purchase

Must have!

You gotta grab the bass knob! it look good and its convenient.

Works great!

I love this bass knob. I have it in another car and it does the job. I recently purchased a kicker amp with a Bluetooth bass knob. Bad mistake, does not adjust like a wired one. Don’t hesitate and purchase this anytime you buy a JL AUDIO amp with a bass knob capability. If amp is adjusted just right, this you only need to turn it up a bit and BOOM THERE IT IS!!

Highly Recommend

Love being able to adjust the bass with this product from the drivers seat. Different music requires different levels of bass. A must have for your system

Nice

Good product worked exactly as described I would definitely buy again

By TEd on July 27, 2021 Verified purchase

Pricey for what it is, but can’t live without it

This is incredibly expensive for what it is, but it is an absolute must when installing a subwoofer because much of the music you play will have different levels of deep bass that will force you to always reach for this knob to adjust your subwoofer’s output accordingly.

By Merle on February 28, 2020 Verified purchase

Great product

I would recommend this product works great for fine tuning your bass to sound great

Control power

Exelente control. Le da mucho mas poder al amplificador . Lo recomiendo jl audio es de lo mejor en todos sus productos

Good for simpleness

Easy to install and locate where you like with or without drilling holes..attached it to my steering column with sticky velcro..it works

A must have for the JL Audio subwoofers

Bass information varies so much from album to album, and even track to track, making this handy knob a must-have. It connects easily to the sub with phone plug-style connector. The goal is to set the sub up without the knob connected and then connect this to adjust the sound up and down from your "normal" set up.

Bass knob

Sonic Electronix makes it easy to find the single parts to sell.

Works like it should

Costs way too much. JL needs to give this away with any sub or amp. Looks good installed operates smoothly.

Just what I needed

Easy to install, it fit exactly where I wanted because of the size

By Damien on April 25, 2025 Verified purchase

Great Knob

This knob is just plug and play and gives you control on the JL Audio JD250/1 amp with ease. Very easy to hide also.

By Timothy on April 18, 2025 Verified purchase

Not bad

This should come with the JL Audio microsubs instead of having to purchase it separate.

By Robert on February 2, 2025 Verified purchase
