I just installed a 500w amp w/ an amp kit (because i kept the factory unit) and a few days after i had a problem, whenever i hit high revs (3000-4000) there is a power surge (dash goes brighter, lights brighten etc.) and the battery light goes on. I took it back to the people who installed the stereo, and they proved to me that it wasn't caused by the amp or amp kit... i have yet to take it to ford. We believe there is a problem with the regulator which is inside the alternator... Has anyone had any problems like this???
