I had the same two ssl’s in the back of a couple of different cars and they always sounded great! never had any problem with them. they did take a while to break in though, but i was ok with that. The nice thing about them was that they were loud and produced nice lows. They were very durable and I say this because I used them for about three years. They did finally blow out just yesterday but im sure it was because of the cold Minnesota weather. Highly recommend these woofers!
