2000 dodge stratus, stereo, wiring

i have a 2000 dodge stratus with a self installed stereo system consiting of a sony cdx300 stereo/cd    kenwood kac-7203 bridgeable 1000w 2ch amplifier   a rockfordfosgate 1 farad capacitor and 2 15" xsite dual 4 ohm voice coils  everything works proplerly but when i use turn signals, turn on A/C, turn on high/low beams, use dome light, role down a window or open a door etc  the stereo and the secondary amp cuts out for 1-2 seconds and cuts back on and will continue to do so untill i have turned the componet off(A/C turn signal etc). could it be the bad ground wires   do i need a bigger battery   i have no idea to witch the problem is caused     maybe bad fuses    any suggestions would be appreciated.

Seems to me like it is a voltage problem, measure the voltage across the terminals of the amp when it is cutting out and lets us know what it is.  Also read the sticky of upgrading your big three this will help out with the voltage issue if thats whats causing your amps to cut out.
