If you are working with tight space but still want real bass impact, the Rockford Fosgate Prime R2SD2-10 shallow subwoofer is built to solve that exact problem. Its ultra-shallow motor architecture lets it drop into compact enclosures and space-limited installs without giving up stability or low-end strength. You still get that solid, controlled bass response that makes your music feel fuller, just in a design that actually fits modern vehicle constraints.
This sub gives you real control over how your system comes together thanks to its dual 2-ohm voice coil design. You can wire it down to 1-ohm for maximum output or configure it to 4-ohm for balance and efficiency, depending on your amplifier goals. That kind of flexibility makes it easy to integrate into different builds without forcing compromises. It is designed for car audio enthusiasts who like to fine-tune their setup instead of settling for a one-size-fits-all approach.


What makes the R2SD2-10 shine is how well it performs across different enclosure styles. In a sealed box around 0.7 cu ft, it delivers tight, accurate bass with clean transients that feel controlled and musical. Move it into a 1.4 cu ft vented enclosure tuned to 42 Hz and you unlock louder, more energetic low-end output with greater efficiency. Whether you want precision or extra punch, this sub adapts to your build goals without losing character.
This shallow subwoofer is engineered for everyday durability with heavy-duty spring post terminals that support multiple connector types including bare wire, banana plugs, and up to 12-gauge wiring. The design is focused on stable performance and clean power transfer so your system stays consistent over time. With its compact footprint, flexible wiring options, and enclosure versatility, the R2SD2-10 is a smart choice for anyone building a space-conscious system that still demands strong, reliable bass.

I put 2 of these in my 13' F150 crew cab and they pound hard. Can't go wrong for the price.
Great product, I ordered two to install in my buddy's '09 Tacoma double cab behind the seats. One unit was DOA and onlinecarstereo was quick to reimburse me. I would recommend this product and the seller!
Love the sub. even if its thin, it can still hit really hard. it also helps as it lets me to save more space. The enclosure that I made for it is also thin so it really helps.
