I was very cautious when i went to buy these subs with the package, but for the price, i couldn't find a better deal! i have heard many subs ranging from jl's to visionik, and these, (BY FAR) hit harder then any of them. the sound quality is good and this package shakes my entire car! i've owned them for about 3 days, but i wanted to write a review right away so people have something to base off of. Incredible package, i highly recommend them!
