[QUOTE="AP0C552, post: 8379904, member: 622198"] Hey man! Is you box partitioned? Is it sealed? I once had two subs in a sealed unpartioned box. Bad idea. They would push against each other in the same space of air. I then wired them up out of phase and the pumped way better. Though this is really not a good solution. If your box is partitioned or ported this wont be problem. I can tell you right now the problem is not your amp. Unless it is faulty. With that amp and those subs you should most certainly be rumbling your mirrors. This sounds like a classic phasing issue. You need to find out FOR CERTAIN that the positive terminal on your amp connects to the positive terminal on your sub. This means first confirming for sure which terminal on your sub is positive. Once this is done, confirm that the subs positive connects to the positive on the box. Finally ensure that the positive on the box connects to the positive on the amp. There are a lot points where this could get mixed up so be diligent. Good luck. [/QUOTE]
