I have recently installed my system in the car, the usual .... a couple of boxes in front, kick bass back and 4 tweeters distributed in space and an output stage to new Radio was due! When searching for a kompackten bass enclosure for my little Ford KA, I came across the JBL Basspro II. About 120 you get here a Active woofer has it all. I'll say this way ... with 100Watt RMS the Sub is not only saving power but he also develops the first full performance .... times turned .... as the first bass came I knew ... OK wiggle my mirror! The pressure is so great that it my Kofferaumklappe with each Basstoß a little anlüpft. Luckily we hear not in the car! It's also nice the supplied gain control, with which you can easily adjust the driver's seat of the sub. Because there are always songs where the bass is either too strong or too weak, a small rotation and finished the mix. Crisp clean bass, I have not managed so far to sub in my volume to overburden. And clear advantage is the power consumption, not even my lights flakern if the sub gets going and in a Ford Ka with standard battery! One problem I had when I saw the Auto-On Switch've tried, he has not turned on, even though music came, perhaps .... to low signal? Do not believe me, but because I always a remote cable to it had does not matter! Still 5 stars, because I've never seen such a well-made sub for so little money, compliments to JBL, you have got hold managed !!! I give the purchase hereby free!
