  • So good!
How I Use It: So, I’ve been using this subwoofer for two months in my truck. Features that stood out to me: The built-in amplifier works great, and I also really liked the complete wiring kit because it simplified my day a lot. The High-Level Inputs & Immerse Bass is pretty good too; I tend to get more work done. My Personal Experience: If I compare this one against the others I’ve used, this one is just plain better. I wasn’t expecting to like the built-in Amplifier as much as I do. Pros and Cons: What was good: Built-in Amplifier, High-Level Inputs & Immerse Bass, complete wiring kit What was not good: none Durability: After two months, it still does its job the first time every time with no fuss. I can’t really ask for more. Final Thoughts: Overall, this is best for DIY tinkerer types. It’s been good for me and my needs, and I’d buy it again. ... show more
