Conclusion: i had a set of these i bought for my truck. put them in a sealed box. they worked great UNTIL. magic smoke happen. well i found out about clipping and was trying to prevent it from happening. 40hz for 5 mins is a bad thing. lol yep i messed up.
Conclusion: I purchased two of these for my new tundra to hide under the rear seat. I have them powered with a 1500 watt rms Rockford fosgate amp. Set to 50% gain. After about 15 min of playing them hard they both blew. I have been going through warranty for months trying to get them back.
Summary: Unbelievable sub. I have had crazy systems in the past. This sub paired with the alpine 6x8 two ways in four doors and alpine tweeters in the front. All run off the alpine 5 channel v9. I had a custom down firing box built for it that fits UNDER half of my back seat. Wasn't really expecting a lot.
Conclusion: Had these in a sealed box, the box cracked and they took some damage from that but they played on. Both blew about 6 months after owning them of hard playing. Ordered 2 more now if these blow again ill probably switch To something different but overall i like em. They hit hard enough for shallows.
Summary: I have 2 12"s in a 1995 single cab F-150 with 2 670 watt pioneer premier amps....2-6 1/2 3-ways in the door and 2-4x8 3-ways in the back and I have never been happier. I had the pioneer premier 12's before.....these blow them out of the water. I have had countless compliments on these sub's.
Pros: Very loud, crisp, clean, and deep bass. Very responsive and amazing sound quality with what little space I have them in.
Conclusion: I bought this subwoofer a year ago and put it in my truck with the alpine pdx-m6. Both units run at 600w rms and I somehow blew the sub the same night. Granted my wiring might have been the problem. I then upgraded some wires and got another one.
Conclusion: I had this sub installed in a 06 f150 supercrew under my back seat. This is a good sub and it sounded great. However for the price(currently 309.00) and the single voice coil config, I would recommend something else.
