Think about it like a hose...you can only push so much water through a hose with a good even flow. If you want to flow more water you need a larger hose. Push too much water through a small hose and it sprays out the end (distortion). But don't go too big or it will just trickle out :thumbsup I used to have a set of Rockford 8" DVC subs. Those little fqrs would hold 300 per voice coil. I didn't get near that, but I was running them at about 400 per sub (200 per voice-coil) and I was using 10ga wire for my subs. Most guys use 10ga for their freakin power wire. By the way, if you're one of these guys (hope you're not ;) ) then go up with your wire. I don't care how small my amp is I always use at least 4ga wire for power with a 4ga ground at the amp to the body and a 4ga ground return from the body of the vehicle back to the negative battery terminal. Yes I know it's overkill, but my systems always sound extremely clean and always make other guys say "Wait a minute, how do you get sound like that out of a system like this?" :)
