Update.
Got the new amp hooked it up no go. Then I moved the amp closer to the battery and got power and 1 Ohm with a shorter ground cable. Seemed to not hit like it should but it was working. I will shorten the power wire and speaker wires should that do it? Its also a 4 channel amp, should I bridge it or not. They are 400 watt subs

It sounds like you should really take it to a stereo shop so you know it is done right. Just to install an amp should cost too much. They know what they are doing and it will save you the headache. Good luck

thanks. I have hooked up in a car before with no issue. I really think it was the length of the ground cable, speaker wire, and power cord. Tomorrow Im going to shorten everything, clean up all the connections. I think it should be good at that point.

I have done may sound systems in cars also, I even did the systems in my last to boats and it is different. In my new boat I had it done professionally and all I can say it WOW!!! what a difference and I also wanted it to be someone elses problem if there are issues. I'm sure you will get it all worked out. Good luck and keep us posted.

4402, Give me a call your speakers are out of phase. common problem

the right pole is going to the right pole on speaker wires. So your saying I have the left hooked up as right and vice versa

What is the fuse rating for the amp itself?

there is 2 x 25AMP fuses on the AMP

so are these dual or single voice coil, and what ohm are the voice coils, sounds like its more of an issue with your power and ground wires than speakers it will normally play for a little bit before it shuts down due to to much of a load, I used to wire up my subs down to .5-1 ohm for db drags and they would play for atleast a song before they over heated and shut down

Can you temp. connect to a battery with a real short length of wire? 8ga is questionable for a 12' run (actually is 24' run, you add the pos and neg wire lengths together) Even thou the manual states use 8ga, the manufacture has no idea on the length of wire you will use, so they can not recommend a wire size with any accuracy.
