[QUOTE="Sound-Man, post: 7936569, member: 646173"] I have been reading this thread, and have not herd anyone talk about power location, as a cause for engine whine or ground loop problems. I have found many whine, poping, or huming problems to be where the power wire for amps and inverters, where hooked to main fuse box or other locations where lower power equipment are hooked to. This lets the higher power of a amp or inverter into the power lines of the lower power items, like your audio deck. Your audio deck picks this signal up and amplifies it to your speakers in a whine or huming sound. The solution is to always hook your power straight to the battery! Make sure your ground is good! Use shielded RCA cables. I only run my RCA's on the other side of the car for mids abd highs with high frequency's. I never had a problem running RCA's on the same side as power with lower sub frequency's. Also Pioneer has really lowered the quality on there lower line decks lately:crying: , and I would stay away from them if all possible. Alpine, Kenwood, JVC, Clarion, Sony are still solid choice's.[IMG]//content.invisioncic.com/y282845/emoticons/clap.gif.178cba2c538c68e720c727fcb024b19c.gif[/IMG] Just my 2 cent's Thanks [/QUOTE]
