Sound problem
 

In my car I got a star sound stereo 2600 watt amp which is running 2 6" By 9" and 2 mid range speakers...............

And i got a Rockford Punch 5000 Watt Mono Block Amp which is running 2 DVC subs 1200 Watt..............................

I got everything wired up nice done by a trained professional guy.........

Every thing seems to be running properly but when i playing music loudly and raving the engine it cuts of the power of my subs..........

I don't know whats wrong.......

Please I am new on this forum, Help with your valuable replies.........

I will be very glad if you do so.............
