Review: Perfect great sound deep bass - Son loved it sounds great deep bass
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.

## 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
