Conclusion: I got this sub as a warranty replacement for another boss sub. I put it in and turned my amp down to break in the new sub. It shorted out after 15 minutes of having it installed. It sounded decent when it worked but not a wise buy.
Conclusion: i have two of these at 1 ohm at about 1400 - 1600 watts rms and they take it all day. its a sealed box and my car has a trunk not open like an suv or hatchback. and i can feel my neck vibrating. every mirror in my car shakes pretty hard. for the price you cant go wrong. the sound is very clean and has a good range of frequency response. these are no mtx 9500's but they over met my expectations. i have no cons about these subs.
Conclusion: Boss-CX124DVC so far, are awesome.......i had some 12 cerwin vegas that were the old paper cone and the woofers popped. Then i put in my RF punch 12" woofers and pop! Put in the boss 12" and BOOM!
Conclusion: I would recommend the Boss CX124DVC speakers. I bought them and installed the set in a 72 Javelin. The sound is great, they were easy to install and wire up to my system. The price was very reasonable.
