Why Choose Alpine W12S4 Component Car Subwoofer?
Bass For All
The 2017 BASS subwoofers are engineered to be fun and loud in a budget friendly category by combining retro styling with enough efficiency to run on 250W RMS.
Efficiency and Tight Bass
An optimized magnet circuit allows more focused magnetism in the gap which results in improved efficiency. This means tighter bass control and more output!
Hard-Hitting Baseline Punch
This 12-inch powerhouse is built around a ultra-rigid, highly responsive polypropylene and mica cone paired with a heavy-duty poly-foam surround, giving you completely distortion-free low frequencies even when you crank the volume.
Frequently Asked Questions (FAQ)
- • What type of enclosure delivers the best bass performance?
The subwoofer performs well in both sealed and ported enclosures when built to the recommended internal volume. Choosing the correct enclosure design greatly improves bass response, efficiency, and overall sound quality.
- • Why does the bass sound weak even though everything is connected correctly?
Improper amplifier tuning, incorrect crossover settings, or an enclosure that is too small are common causes of reduced bass output. Adjusting the amplifier and verifying the enclosure specifications usually restores stronger low-frequency performance.
- • Can I use this with my factory stereo system?
Yes, it can be integrated into many factory audio systems when paired with a compatible amplifier and signal converter if needed. A properly installed amplifier allows the subwoofer to perform much better than relying on factory power alone.
- • Why does the subwoofer distort when I increase the volume?
Distortion is usually caused by amplifier clipping, excessive gain settings, or overpowering the subwoofer. Proper amplifier tuning and matching the amplifier's RMS output to the subwoofer help prevent distortion.
- • How much amplifier power should I pair with this?
An amplifier that closely matches the subwoofer's recommended RMS power rating will provide the best balance of output and reliability. Using the correct power level also helps prevent both underpowering and accidental speaker damage.
- • Why does the cone move very little while playing music?
This may happen if the low-pass crossover is set incorrectly or the amplifier isn't receiving a strong input signal. Reviewing the crossover settings and checking all signal connections usually restores normal cone movement.
- • Can I install two of these subwoofers in the same enclosure?
Yes, many enthusiasts install a pair to achieve greater bass output and improved low-frequency coverage. Just make sure the enclosure volume and amplifier are properly matched for the combined system.
- • Why does my trunk or vehicle interior rattle so much after adding this subwoofer?
The increased bass output can cause loose trim panels, license plates, and interior components to vibrate. Adding sound-deadening material and securing loose parts significantly reduces unwanted rattles.
- • Does this subwoofer need a break-in period before it reaches its full performance?
Yes, many users notice smoother and deeper bass after several hours of moderate listening. This allows the suspension components to loosen naturally and perform as intended.

I have two 12s and the subs r amazing nice clean bass I give them 5 stars.

Awesome sub. I’m a huge fan of Alpine subs now. Will probably buy more Alpine products in the next month. Maybe mids first before tweeters. But I’m really convinced that is the best brand in the market right now.

A much cheaper sub from Alpine. No issues with the performance as its sound quality is one the best I’ve heard for some time now. I’m even shocked that its less than $100. Nice to know that you don’t have to break the bank anymore for a quality sub.
