## Customer Reviews

### ⭐⭐⭐⭐⭐ 10 years still strong
*by A***R on May 20, 2025*

I have now owned this sub amp combo for 10 years. When I first hooked it up, I had a seperate amp not realizing it came with one. How could it be this cheap and have its own amp? I hooked it up to a 2f capacitor (I recommend at least 4, 8 is better) to ensure clean power delivery.. and it knocked my socks off. This is not a competition sub. But for music lovers that want clean bass and decent thump that won’t rattle your windows out, THIS thing delivers!! Highly recommended, still going strong after 10 years… I only have had to replace my capacitor due to it being underpowered and hard on my alternator.

### ⭐⭐⭐⭐⭐ Definitely recommend
*by A***S on February 1, 2025*

Great speaker so far super easy set up once you’ve run the wire through your car. Got some real power and thump! Average size fit perfect in my trunk.

### ⭐⭐⭐⭐ Pretty good for the price
*by R***E on December 2, 2020*

This is a pretty good deal once the speaker is broken in. It sounds pretty distorted for the first week but after that it smoothed out. Good power and adequate bass for upgrading stock system. I'm satisfied
