[QUOTE="john.mulvehill, post: 6962688, member: 625086"] I just purchased a HO112R-W7 and used a JL 1000/1 amp to power it. The audio shop set the gain on the amp to about a third of the way up. I am using a factory head unit on a Pontiac G8 GT and running 4 gauge wire. My battery is in my trunk. As soon as I drove away from the car audio store with this particular sub and amp, I smelled a weird smell in the car. I drove home about 20 minutes and then parked the car. I went out about an hour later to pick up dinner and the bass cut out after driving 5 minutes. I pulled over and opened the trunk only to find smoke coming out of the sub. I took it back to the audio shop today and they now have to send it back to JL. How did this happen? Is it because the subs were not broken in yet? I was not playing them too too loud. What's even more confusing is that I smelled that weird smell right after driving away from the shop. The sub and the amp were both new equipment. A replacement sub should be arriving in a couple weeks. What can I do the next time to ensure that I break the sub in properly and how do I keep it from blowing? Is one third of the way up a proper setting for the 1000/1 amp to power the 12w7 in a high output ported box? I thought the 12w7 matched the 1000/1 really well and I did not think there was a danger in them blowing out that easily. Any help would be greatly appreciated. Thanks, John [/QUOTE]
