Why Choose Alpine SS-SB12 Enclosed Car Subwoofer?
Alpine 12" S-Series Shallow Preloaded Subwoofer
Now you don’t have to choose between bass and space! This 12” S-Series Shallow Preloaded Subwoofer Enclosure measures just 5.25” deep, delivering clean, powerful, and reliable bass while fitting seamlessly into most vehicle applications.
Powerful and Compact Performance
The SS-SB12 packs a 2” voice coil and a lightweight neodymium magnet, delivering up to 300W RMS of clean, punchy bass. Its front-mounted magnet motor allows for an extremely shallow enclosure, giving you big bass in a compact footprint.
Next-Level Bass Control
Alpine’s Gen2 DD-Linear Magnetic Circuit uses a compact dual-gap voice coil for superior motor control, delivering 22mm peak-to-peak linear excursion for powerful, distortion-free output. With dual voice coils wired in parallel (2 Ohm load), the S-Series 12" Shallow Subwoofer Enclosure is optimized to perform perfectly with Alpine S2-A55V, KTA-200M, or KTA-30MW amplifiers.
Frequently Asked Questions (FAQ)
- • Can I connect this enclosed subwoofer to my factory stereo?
Yes, it can be integrated with most factory audio systems when paired with a compatible amplifier and the appropriate signal converter if required. This allows you to enjoy significantly deeper bass while keeping your original radio.
- • Why does the bass seem weak even though everything is connected correctly?
Weak bass is often caused by incorrect crossover settings, amplifier gain adjustments, or the enclosure's position inside the vehicle. Fine-tuning the system and trying different enclosure orientations usually improves bass performance noticeably.
- • What size amplifier should I use with this subwoofer?
An amplifier with an RMS output that closely matches the subwoofer's continuous power rating provides the best balance of performance and reliability. Using the proper amplifier also helps prevent distortion and unnecessary speaker damage.
- • What gauge speaker wire does the terminal accept?
The recessed spring-post terminal cup accepts wire up to 12-gauge. Using anything thicker won't fit properly into the posts, so 12-gauge or thinner is recommended for a secure connection.
- • Does the direction the enclosure faces inside the trunk make a difference?
Yes, enclosure orientation can have a noticeable effect on bass response depending on your vehicle's cabin design. Many owners experiment with different positions to find the strongest and smoothest low-frequency performance.
- • Why does the bass distort when I turn the volume up?
Distortion is usually caused by amplifier clipping, excessive bass boost, or gain settings that are too high. Proper amplifier tuning and crossover adjustment help maintain clean, powerful bass at higher listening levels.
- • Can the mounting brackets be repositioned for different trunk shapes?
Yes, all four brackets can be adjusted to face out the sides or the ends of the enclosure. This flexibility helps it conform to irregular spaces like wheel wells or angled trunk walls.
- • Why does my trunk or rear hatch rattle after installing the enclosure?
The increased low-frequency output can cause loose trim panels, license plates, and interior parts to vibrate. Installing sound-deadening material and tightening loose components usually minimizes unwanted rattles.
- • Is an enclosed subwoofer easier to install than building a custom enclosure?
Yes, a preloaded enclosure is designed specifically for the included subwoofer, eliminating the need to build or tune a custom box. This provides reliable performance while reducing installation time and complexity.
- • Is it actually water-resistant enough for a boat or truck bed?
The polymer enclosure carries an IPX water-resistance rating, so it can handle splashes or damp conditions better than a standard MDF box. It's still not meant for full submersion or constant direct exposure to the elements.
