You really need to carefully consider what amp you get for your sub amp because that is the amp that is going to work the hardest. Powering subs draws a lot of current from an amp. That is why some people's headlights dim on a heavy bassnote. And cheaper amps, like Legacy or Pyramid, don't handle that current draw very well without introducing A LOT of distortion into your subs. And distortion is the reason that speakers blow 99% of the time. So, I would suggest that you spend a lil more money and get a high-quality amp. I've been selling car audio for quite awhile and one of the lines that I have sold is MTX. MTX makes great amps for their price. And if you can find a mom and pop store that sells it, you can try to talk them down on the price cuz there is a ton of profit in those amps.
