## Description

Alpine SWT-12S4 1500W Max (300W RMS) Single 12" Sealed Subwoofer Tube Enclosure

Review: For Deep Not Fast Bass - I bought my 12" Alpine sub for VW Passat. First was 8" 150W one :-( Alpine Fits perfectly with extra room left in any dimention. Quick easy connection with banana plugs. In my case plugs not so secure in place. Had disconnection issue. Always mount and secure sub to the floor before use. Do not let it roll in the trunk for max performance. Or operating at all lol Sub very boomy on max. I would recomment installation of Bass knob too for volume adjustment. Tube subs Not situable for quick bass. Like in Techno music. Pop music sounds wonderfull. Bass Very deep and enjoyfull with right music.
Review: Feel your insides shake with this sub! - This thing hits hard. I have it hooked up to a Rockville that pushes 360 watts rms. I tuned the amp to the subwoofer and when the bass drops you feel your insides shaking and it almost takes your breath away! My windshield shakes so hard my rearview mirror won't stay in position! I do have the gain turned down on my amp slightly to match the recommended rms watts of the subwoofer. For the price and the quality of sound I would definitely recommend to friends, family and neighbors or anyone else asking "WHAT DO YOU HAVE IN THERE?!"

## Questions & Answers

**Q: Is an amp needed with this or is there one preinstalled?**
A: You will need an amp. I have an Autotek 1500 class D. A bet overpowered but gains and crossover set right. Sounds pretty good, yet struggles at super low notes. I plan on upgrading the sub later. Good build, solid.

**Q: Is that a port I see in the image?**
A: Exactly what I saw.. ported in picture but sealed in listing. They need to get it together

**Q: What do you mean by fast bass?**
A: It doesn’t have to wait to warm up the voice coil

**Q: Is a kenwood xr601-1 excelon 600-watt monoblock rated at 400 watts rms at 4 ohms single to much amp for this subwoofer?**
A: Nope...I have that much power and still believe it can handle more

### ⭐⭐⭐⭐⭐ Wow! This tube is amazing! Way to go Alpine!
*by F***Z on April 18, 2019*

Perfect fit in the opening behind the rear seat in my 2013 Fort Taurus. The bass response is amazing, pushed by a 300 watts (bridged) amp. I had a 12” Rockford Fosgate sub in a shallow box (see picture), and it was weak and a disappointing. The Alpine 12” sub is amazingand a great deep pounding bass experience. Update: Oct 2021; Sold the Taurus, so I transferred the same setup to my 2016 Toyota Avalon. Fits perfect and still sounds amazing.
