i took a road trip to the {Philadelphia from Chicago, the system went smoothly, but few restarts were needed, glitches, and my 10.4 Lilliput constantly went off/on

here is what i have

OPUS 150W
REAR OVERHEAD MONITOR 15W
TOUCHSCREEN powered though cigarette plug, it was blowing fuses before 15W
500W inverted for XBox 360 100-250W
JL 4 channel amplifier 450W
Alpine Mono Amp 350W

everything ran of factory VW battery battery received 4 gauge from the alternator, and i made ground a 0 gauge wire.

keep in mind VWs are electrical guzzlers, i am thinking of adding a batteryf or the smoother application

what do you guys think
