Car: '95 Eclipse
Head Unit: Pioneer (Older, need a new one)
Front: 6.5" Infinity Kappa Perfect 2-Way Components
Rear: 5.25" Infinity Kappa 2-Way 52.5i
Amp: Rockford Fosgate 400.4
I recently installed rear speakers and they have a whine noise to them based on my engine RPM. The sound is there when the head unit and amp are on and off. It gets louder the higher the engine RPM and is not effected by head unit volume. The front speakers do not have any whining noise at all.
I would like to know if this is being cause by a power wire running beside the rear speaker wire? I though that engine noise would really only be audible if it was being amplified (example: power wire next to RCA cables).
I do not think my power wire is ran along side of the rear speaker wire, but I will double check. I would just like to know what to look for before I start.
Thanks in advance.
