PWE-S8 Works Great!

The following review is for PWE-S8, which is a part of the bundle you are viewing.

I wanted a compact powered subwoofer that I could tie into my factory head unit to give me fuller base. This absolutely fit the bill. I'm very happy with its size and sound. The remote adjustment knob is very convenient.

One thing that wasn't clear what the pigtail comes with a fuse on it. Unfortunately, you have to add a second fuse to keep it close to the battery.

Super surprised!!!

The following review is for PWE-S8, which is a part of the bundle you are viewing.

I was very skeptic with this product. I have never used a sub that small, always stuck with 12s or 15s but i was doing this for my brothers SUV who didn't want to give up any trunk space. It works really well for what it is. Pretty decant kick on the bass and it does get surprisingly low, not crazy but definitely way more then I expected. I also recommend using the metal brackets it comes with so you can properly mount the sub to the seat bolts or to the floor to make sure that the bass coming from the sub can resonate with in the car.

Small but Mighty

The following review is for PWE-S8, which is a part of the bundle you are viewing.

This sub was shockingly powerful upon first use. Perfect for anyone wanting an excellent bass upgrade all while saving your trunk. Easy enough setup with the built-in amplifier. Overall, quite a good subwoofer.
