Need some help please

My amplifier has been acting up lately. It is a Rockford Fosgate 160.2. It pushes 160x1 watts RMS. I just hooked it up to a new sub. The problem is....it keeps cutting out every once in awhile. It does it really bad in the winter, and the first 2 or 3 minutes when I'm in my truck. Its done it with my last 3 subs. The wierd thing is.....it doesn't cut out completely. It just gets softer and decides to turn into a pu$$y. I'm probably gonna get a new one down the road, but I just wanted to hear from some car audio people, just to hear what they thing the problem is? DO I have it wired right? The sub has dual 4 ohm voice coils, and I have the negative wire to the negative one, the positive to the positive. The other two terminals on the sub are a positive with a dot, and a negative with a dot. I wired those together too using a different wire, because that's what some wiring diagram said to do. IS THAT RIGHT? I appreciate ANY kind of feedback. THanks!

You need to parallel the connection.  Sounds like that the way it is hooked you have a 8 ohm load.  That is not good for your amp.  Connect the red terminal to the RED / white terminal then out to the positive connection of your amp.  Connect the black terminal to the BLACK/ white dot terminal then out to your amp.  If that amp is hooked on a 8ohm bridge it must really be heating up and lacking a lot of power.  I hope that this helps.  I am sure that others will also chime in with their thoughts.

Refer to your other post for more details.

If you wire that sub in parallel and bridge you will be presenting a 2ohm mono load. That amp will not support it and will either shut down and fry, or will go into protect mode.
