Odd System Cut-Out Problem

Alright, my three amps combined (2 Rockford & 1 Visonik) are pushing 1850 watts RMS. I have no electrical system upgrades, stock battery & alternater, except for a 1 farad cap. The issue is...

Due to faulty engineering, I have to manually turn my head unit on & off. What I turn it on, it plays fine. When I start the car, it plays fine. But when I put the car in reverse to back out, the entire system pretty much cuts out for a split second. It doesn't cut out completely, but acts as if the volume was suddenly turned down to one, then directly back up to its previous state. This doesn't happen any other time, only when I initially put her into reverse.

Any suggestions? I'm at a loss.

Thanx in advance.

Do you have all three amps running off the one remote wire ( without a relay ) ?? If so, you may need a relay for the remote connections of the amplifiers. Also, where did you mount the ground for the HU ?

Relay for the remote wire...duh...i'm an idiot.

Thanx again Jeff, I have no clue why I forgot that.
