Alpine KTX-LK10 10-Inch PrismaLink™ Enclosure Linking Bracket Kit
Product overview:
The Alpine KTX-LK10 is a specialized hardware expansion kit designed to seamlessly connect multiple 10-inch Alpine PrismaLink™ S2-SB10 subwoofer enclosures. Whether you want to step up to a dual-sub setup or create a massive "bass wall" with three or four enclosures, this kit provides the structural integrity and aesthetic finish needed for a professional multi-sub installation.
Features
Seamless Connectivity
The KTX-LK10 is engineered for unlimited multi-link capability. It allows you to mechanically join two or more S2-SB10 enclosures together so they function as a single, rigid unit. This modular design gives you the flexibility to start with one subwoofer and "stack" your system over time as your bass needs grow, without ever needing to replace your existing boxes.
Safety & Convenience
Constructed from heavy-duty steel, the kit includes both front and rear link bracing to ensure your enclosures stay perfectly aligned and securely fastened. It is a comprehensive "bolt-on" solution that includes all necessary mounting hardware. By anchoring the boxes together, you eliminate the safety hazard of individual enclosures sliding or tipping in your cargo area during spirited driving.
Effortless Lighting Expansion
One of the standout features of the KTX-LK10 is the included RGB wiring harness. This allows you to extend the integrated RGB lighting trim bars from one PrismaLink™ enclosure to the next effortlessly. The front bracket also features a silver trim design that matches the PrismaLink™ aesthetic, ensuring that the visual "glow" and hardware finish remain consistent across your entire subwoofer array.
Fine Tune Your Sound
By linking multiple 10-inch enclosures, you can tailor your sound setup precisely. Doubling or tripling the number of subs increases the total cone surface area, allowing for significantly higher sound pressure levels (SPL) and deeper low-frequency extension. Because the brackets are precision-cut for the S2-SB10, they maintain the perfect spacing for the side-firing ports, ensuring your audio performance is never compromised by the physical connection.

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.
