Memphis Audio MJ1212 MOJO 12" 1500W Selectable Subwoofer
The Memphis Audio MJ1212 is a high-output, competition-grade subwoofer redesigned to deliver brutal, hard-hitting bass with legendary old-school style. Known for its iconic orange cast aluminum basket, this 12" beast combines a massive motor structure with advanced thermal management to handle 1500W RMS. It features Memphis's patented FLEX technology, allowing you to instantly switch between 1Ω and 2Ω impedance to perfectly match your amplifier's output.

Patented FLEX Technology: Features a tool-free selectable impedance system. Using the included jumper plug, you can instantly switch between 1Ω and 2Ω to optimize your amplifier's performance.
-
Massive Motor Force: Driven by a gargantuan 300oz triple-stacked magnet structure that provides the raw power needed for unrelenting low-end performance.
-
Extreme Excursion: Engineered with a beefy high-roll surround allowing for massive air movement (1" Xmax) and up to 1.75" of mechanical excursion for violent bass response.
-
Advanced Thermal Cooling: Equipped with DVVC (Direct Vent Voice Coil Cooling) and a vented cast aluminum basket to rapidly dissipate heat, preventing thermal shutdown during intense play.

What Others Are Saying
Eddie was great - SDCS installed a new head unit in my 2019 4Runner. He was honest in his opinions regarding the options I was considering. Pricing was also good - he was able to reuse some of my existing installation kit so I saved a bit of $$.Installation was clean and fast and he took the time to walk through the features before I left. Highly recommend!!
I had a great time at this shop! The staff really knows their stuff and took the time to explain the different options without pressure. Installation was quick, clean and professional. Everything looks factory and sounds amazing. The prices were fair and customer service was above and beyond. I highly recommend this place if you're looking for quality car audio and excellent service.
Those guys are really professional! I had a new Alpine floating head unit installed in my 2008 Mercedes, and it feels like a brand-new car. The installation was super clean. At first, the sound wasn’t the same as the factory stereo, but Kevin tuned it to be just as good—if not better—without adding any new amps. They even used my factory GPS antenna so I don’t have extra wires hanging out. On top of that, they matched the online price. Big thanks to Kevin and Eddie—highly recommended!
Kevin was awesome, he took his time and explained everything to me. I went in initially for a dash cam install and then decided to get a sub and amp installed as well. Both turned out great and will be returning if I need more work done.
Came In not knowing what to expect when suddenly my stereo stopped working. Spoke with Kevin in the front and after a VERY fast diagnosing they discovered my wiring was incorrect. After only about 45 minutes total being in the store I was on my way to the beach with a working stereo again! Thank you so much SDCARSTEREO
Highly recommend Kevin and the team at San Diego Car Stereo for any issues with aftermarket stereos. I bought a car with an aftermarket stereo and AC unit that wasn’t working properly—specifically, the heat wasn’t functioning due to an improper setup. I had several people look at it with no luck, and even the dealership basically refused to help because it was an aftermarket install. I came to Kevin and his team over the holidays feeling pretty defeated, but he was confident he could get the heat working before I headed back to a Colorado winter. Sure enough, he got it done.
