Posted August 1, 201114 yr I have a whine sound i my front speakers, sorta like an alternator whine . It get a little louder with motor rpms. But here is the odd thing, it only does it when car is really hot and when i take it out of garage and its hot. If its night time or cool outside and car has been seting outside no noise. Any ideas on what it could be? oh and its only two of the four channels on the amp making noise.
August 1, 201114 yr Author Have you checked all the grounds? That is the likely culprit.checked the grounds today, all secure. maybe i will pull the head unit out next when i have time. that only when hot thing really stumps me . when it starts to do it again im going to switch my rca cables around with my other amp or channels to see if its the amp or maybe rca cables.
