Features
Slipstream™ port design
At high sound pressure levels, air flow turbulence inside a vented enclosure’s port can create noise that sounds like woofer break up. The patented Slipstream port in Series II enclosure uses a double-flared design to minimize turbulence, and eliminate unwanted vortices.
SSI™ (Selectable Smart Impedance)
Most car audio system designs call for 2- or 4-ohm impedance. Series II subwoofers feature an exclusive dual impedance switch that lets you choose either load impedance option. Not available from any other manufacturer, SSI lets you reconfigure your system by simply flipping a switch.
High-roll surround
Series II enclosure incorporate a high-roll surround that provides superior cone edge suspension while maximizing excursion. It not only increases the cone area, it also provides remarkable linear stability and reliability.
Proprietary cone design
JBL subwoofer cones aren’t just built to thump, they’re built to last. Series II enclosure feature an exclusive cone design that delivers superior rigidity for long-lasting performance.
Long excursion design
The longer a subwoofer’s excursion is, the more air it moves. And the more air it moves, the more bass you feel. The long-excursion design in Series II enclosure ensures big, deep bass output. Just the way you like it.

Hi, I just ordered the S21224SS at best buy store and will ship in the next few days, just wanna know which one jbl amplifier is the bestand compatible for that subwoofer? Thank you
From what I’ve seen in this thread and what I’ve researched the GX-A3001 is a good amp for this. Idk if that’s JBL but I’ve heard good things about it.

What is the best amp from JBL to pair up with this sub?
The S2-1224SS can handle 275 watts of RMS power handling. This means that any sub amp with an impedance of 2 or 4 ohms and a power output of 275 watts will work fine with these speakers.

Is there a different RMS at 2ohm and 4ohm settings?
The S2-1224SS can handle 275 watts of RMS power handling. This means that any amp with an impedance of 2 or 4 ohms and a power output of 275 watts per channel will work fine with these speakers. That said, the power that the speaker can handle remains the same whether it's switched to 2 or 4 ohms.

I have two sets GTO609C and a single S2-1224SS (over kill for a 1968 Volvo 122 Amazon). I was considering a GX-A604 to drive the two sets GTO609C and a GX-A3001 to drive the S2-1224SS. Am I in the right direction or is there a better solution?
Yes you definitely are in the right direction. The amps would work perfectly with your speakers .

Is it supposed to make a popping sound when I first turn the car on? It’s a S2-1224SS and it only started doing this about a week or two ago and I want to figure out why the popping sound. Recently had my alternator changed too, if that helps
Thanks for bringing this to our attention. Our JBL S2-1224SS speaker system should not make a popping sound when you start the engine of your car. Your best course of action, for now, is to bring your automobile to the professionals who installed the unit or you can call our customer support so we can refer you to an authorized service center and have the unit diagnosed.
