Review
I installed these in my ride and they bang. For them being 3 inch subs you wouldn't think they would but i was wrong. They're not loud enough to rock the car next to you which my truck has been installed with sound insulation so you can't really hear anything outside of it. You get them cranked up enough and they'll rock you pretty good. So if your wanting a good quality sub loud enough to rock you and your friends, with the looks and performance of a high quality sub at an AWESOME price, this is definitely the sub for you.

What I like
The performance that it had to provide is tremendous.

What I do not like
It may be slightly expensive compared to others of its size.

Review
I had almost a good sound system, until I realized that the dispersion of the music was quite bad. I went online to search for recommendations; some suggested that I strategically relocate where my speakers are, others suggested I look around for coaxial speakers. I then went to my relative's shop who sells in-car entertainment products, and asks for his recommendation on the coaxial speakers, since I wouldn't want to spend a bomb relocating. He suggested I get this Audison AV 3.0 for he had gotten a lot of good feedback from customers who bought this. I went ahead to get them, and I do agree with the other customers. I now feel every single corner and edge of the car has been 'enlightened' with my delightful music.

What I like
I love how it had distributed and dispersed the music more evenly throughout my car.

What I do not like
It may cost a little expensive.
