Why Choose Alpine RS-SB12 Enclosed Car Subwoofer?
Halo Series
Alpine's Halo Series of subwoofer enclosures deliver sound and style in preloaded sub boxes. Now the RS-SB12 12” subwoofer joins their lineup of space-saving shallow-mount solutions.
Cast Aluminum Frame
The enclosure contains an RS-W12D2 subwoofer dual-voice coil subwoofer wired to provide a 2-ohm load. This shallow sub features a cast aluminum frame, polypropylene cone, and butyl rubber surround, and handles up to 600 watts RMS (1800 watts peak) so you'll get the big bass you're looking for.
Steel Mesh Grille Protects Your Speaker
The rugged medium-density fiberboard enclosure is only 5.25” tall, and is covered in tough and attractive black carpet. The included rubber feet can be installed on the top or bottom, so the enclosure can be installed as a downward- or upward-firing enclosure for maximum flexibility. A steel mesh grille protects your speaker from accidental damage.
Frequently Asked Questions (FAQ)
- • Will this enclosed subwoofer work with my factory stereo system?
Yes, it can integrate with most factory systems when paired with a compatible amp and signal interface. This lets you add real bass without replacing your head unit.
- • Why doesn't the bass hit as hard as I expected?
This is often due to amp tuning, crossover settings, or sub placement. Adjusting the amp and testing enclosure position usually improves output.
- • What amplifier should I use with this enclosed subwoofer?
An amp with RMS output close to the sub's rating gives the best balance of performance and reliability. Proper power matching keeps bass clean and protects the sub.
- • Can I place the enclosure in different positions inside my trunk?
Yes, it can often be positioned in different directions to optimize bass for your vehicle. Testing a few placements helps find the strongest response.
- • Why does the bass become distorted when I raise the volume?
Distortion usually comes from amp clipping, too much bass boost, or aggressive gain. Proper tuning and crossover adjustments restore clean bass.
- • Does this enclosed subwoofer require a break-in period?
Yes, many owners notice smoother, deeper bass after several hours of listening. This lets the suspension loosen naturally for consistent performance.
- • Will it sit flat and stable if my vehicle's floor isn't level?
The height-adjustable rubber feet are built to handle uneven floors without rocking. Adjusting each foot individually helps prevent buzzing.
- • Is a preloaded enclosure better than building a custom subwoofer box?
A preloaded enclosure is matched to the sub for predictable performance with far less installation effort. It's ideal for solid bass without custom box design.
- • Can I mount it facing up or down depending on my install location?
Yes, the adjustable feet can be set on either side, letting it fire upward or downward. This gives flexibility depending on your trunk layout.
