I would not recommend this product simply because it is not worth the money....I was only looking for a starter kit just to see how much sound I really wanted in my car....Visonik sounds good within my car ONLY with all four windows rolled up but on the outside, you can't really hear anything...I am ready to upgrade to something much bigger and better because I like "REAL" sound in my car. Visonik is so bad that when I tried turning the amp up it would sizzle and when I tried turning the subwoofers up they would fade in and out....however, the style of the box is great because it fits right in my trunk with no issues. Hope that this will help anyone that is looking for the "Perfect Sound" for their car.
