I have a sealed 1503, and I was wondering if I will know when it bottoms? Will it be like an SVS and have that clanking or jackhammer like sound. I also have a question about the amp? I have a Crest Lt-1000(Awesome amp highly recomended) and it has a clip protection and line leveler phase when it reaches a certain point. Is it ok if it peaks into this region as long as its not constant? My sub is fine after the beating it had tonight, I just had one scene on Joy Ride where the sub when into the red area and sounded pretty distorted. I dont think it bottomed. Is this OK for the amp and woof?
