I had speaker hooked up in seres pos neg pos neg keep cutting off.does it take 17 volts to get 4000 watts out this amp.will it push the 2 18 speakers

you might need to see what your volts are if there 14.4 at the amp thats good but see what they drop to ....

The easiest way to think of wiring voice coils and subs is this:
In this case, you want to wire two subs, each with dual 4 ohms voice coils, so that the total equals 2 ohms. Your options are:
With two, dual 4 ohm subs, you can only have 1 ohm or 4 ohm total impedance.

The amp says it's 1 ohm stable, so assuming the DVCs are dual 4 ohm, you should be able to connect all "+"'s together and all "-"s together, like the picture below:
As for the amp shutting off for a few seconds, it sounds like it's either:
A) Not getting enough power at high volume.
OR
B) Overheating.
The cap on the +12V to the amp should help, but putting a meter on the +12V might tell you whether it's dropping too low (<11V).
When you first turn the volume up, how long does it work fine before shutting off? Is it with the vehicle running or not?

start with the lowest settings on all the adjustment knobs and turn your radio up to about 3/4 of the volume and go from there

Placing the speakers next to each other face down, you will notice that the connection points run in sequence +- and +-. Now connect the - (negative) from the one speaker, to the + (positive) of the other speaker. Now connect the open + from the one speaker and the open - from the other speaker to your amp. Your amp should have a bridging indication. On the connection points of the amp, you should see a mark pointing to the first + and the last -. That will be your bridge and thus utilizing the full potential of your amplifier
