right, im having a re-occurance of a problem i had couple of weeks ago, when system turned up loud, big amp shuts down, even when driving (with fuse box and power cap both showing volts between 12-14), the battery light keeps flashing! could my amp be knackered? why would this cause battery light to flash on?, surely when driving battery size/power should not be an issue?? do i need a bigger battery?? soz 4 the essay, cheers
