Hi every one i am new in this forum, Please assist me

I got a mono bloc amp Its Rockford punch 5000 watt 2 channel, Which is running 2 DVC subs 1200 watt and a star sound 2600 watt 4 channel, which is running 2 pioneer 6" by 9" and 2 mid range speakers. I got everything working properly and everything is wired up nicely by a trained professional guy. but the problem is when i am raving the engine it cuts off the power from the AMP. But when i am driving it it works perfectly.

Can anyone tell me what to do.......

 

it is due to some wire shortage or may be due to raving the it produced more electric power and may be for the safety of sound systen there whould be a electric detactor whic cut the electricity

 

Geeze we are in need of a sort of expert in the Stereo Sound Systems..is there any one who reads this that is MECAP qualified?..
