any new info on this? im getting the same exact problem ever since i upgraded the ground wire on the battery i have under the hood. i had the stock 8 or 10 gauge ground and a 0 gauge power from the front to the back. but since i had 0 gauge everywhere i decided to upgrade the stock ground on the battery to 0 gauge ever since i did that the lights get brighter when the subs hit which is kind of weird... its ONLY when the subs hit.
