ill second 80, what do you have ur speakers crossed at?

Completely setup/install/vehicle dependent. Basically turn the knob till it sounds best. But, as a general range, it will probably be somewhere between 50 and 85hz. Don't limit yourself to a single number //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif And honestly there is no way for anyone sitting on a computer half way across the country to be able to tell you what frequency to set it to.

Yeah they are in a ported box. They sound like they are clipping at a certain freq. and it sounds like shit. Almost like they are gettin pushed too much or sumtin. I've been playin with the setting for awhile now. I got the the SSF turned up about 3/4 of the way, but cant figure out the X-Over

Also, could it also be becuase of the ports aren't tuned right?? It just sounds like the subs are gettin pushed too much....

You could be sending them too much power. Mechanical power handling is box dependent.

How can i reduce the amount of power going to my subs?? I know my subs are 300 RMS and can hadle somthing like 800. And my amp is around 1200RMS, so it should be giving 600 to each sub right??? Is that too much, and if so, how do i reduce the power?

that amp can do up to 1.4kW, it's pretty underrated...

go to the sticky on amp gain setting to determine exactly how much power you're sending the subs, and use that method so you can dial it in exactly how much you should be.
