Re: >>>Engine whine and ground loop fixes... take two
After re-installing my setup, I noticed alternator whine at low volume. Checked the grounds on both amps, making sure they were as short as possible. I'm using Streetwires Musica100 and 200 RCA cables along with OFC Streetwires power & ground wires BTW.
Come to find out, it was the MTX 250x amp. Swapped it back to the Alpine 3547 and noise was gone. In some cases, it's a component causing the noise, other than a headunit.
* MB Quart 6.5 components (front door)
* MB Quart 6.5 coaxials
* Alpine 3522S
* Orion HCCA 225 (3rd Gen)
* AudioControl 2XS
* Pair of American Bass XD844 8" subs (1.9 ft ported box, tuned @ 35Hz)
