#1769987 - 05/18/09 11:47 PM Whining sound in radio on accelerate with new XM
Carter Carter Member Registered: 10/03/08 Posts: 342 Loc: Michigan	Hey All, I am getting a whining sound out of my radio when I am accelerating when in sat mode with my new XM installation. I remember a long time ago this was a problem with older cars, but I didn't think it would do it here, any suggestions?

trickvic trickvic Rookie Registered: 08/09/08 Posts: 93 Loc: West Los Angeles	Definitely sounds like a grounding issue. Is the ground of the xm module connected to the same ground as the radio? are all the audio cables kept separate from any cables carrying power? Depending on how its hooked into the head unit you can buy a ground loop isolator (noise filter) which should dampen the whine, but that should be second to checking all the wiring. I had the same thing happen with a set of speakers i hooked up in the trunk, turns out i just needed to route some wires differently. _________________________ - 05 P73 - custom x-pipe no mufflers - custom 91 octane sct tune - 04 CVPI airbox/80mm MAF - interceptor center caps, underglo, interior underglo, rear flashers, xenonworks 8000k HID's - kenwood KVT-512 flip out dvd, 4 Kicker DS680 6x8's, 2 12" Power Akoustic 800W RMS each wired to 2 Ohms, lanzar vibe 1600W RMS 2400 PEAK 2 channel amp, 2 farad cap, 2 alpine type r 6 1/2" speakers in trunk for mid/high's while tailgaiting.

Carter Carter Member Registered: 10/03/08 Posts: 342 Loc: Michigan	It maybe the way I routed the antenna wire too. I will check it all out this weekend, and get back to all y'all. Its not bad when louder music is playing, but softer music, it gets annoying. As for the way it draws power, it gets its ground and power off the radio. Its a factory CD6 radio.

trickvic trickvic Rookie Registered: 08/09/08 Posts: 93 Loc: West Los Angeles	it might be the antenna. but isnt xm digital? I'm no expert and the antenna may be picking up stuff, but since its digital it would seem like your noise is coming from inbetween the module and the radio. In my experience RCA cables tend to be the ones to pick up the most noise. Is everything wrapped and away from live wires? _________________________ - 05 P73 - custom x-pipe no mufflers - custom 91 octane sct tune - 04 CVPI airbox/80mm MAF - interceptor center caps, underglo, interior underglo, rear flashers, xenonworks 8000k HID's - kenwood KVT-512 flip out dvd, 4 Kicker DS680 6x8's, 2 12" Power Akoustic 800W RMS each wired to 2 Ohms, lanzar vibe 1600W RMS 2400 PEAK 2 channel amp, 2 farad cap, 2 alpine type r 6 1/2" speakers in trunk for mid/high's while tailgaiting.

Carter Carter Member Registered: 10/03/08 Posts: 342 Loc: Michigan	Yeah there are RCA Cables going from the XM Tuner Box in the Glove Compartment passing up through the limited space between the air ducts behind the dash to the interface behind the Radio. I never thought about the RCA cables. Yes, XM is digital, so your right no noise should be coming from there. _________________________ 2003 Mercury Grand Marquis GS M74 47k - Current Mods- Marauder Cluster Swap w/ Autometer 9117 TA, Auto dimming Gentex Mirror, Overhead Console w/ Home link Compass, 6000K H.I.D. w/ Philips Ballasts, 06+ Audiophile CD6 Radio with XM Satillite Radio Direct Connect, Wood/Leather Steering Wheel with Redundant Controls Coming Soon - EATC, Leather Interior with Heat, Marauder Wheels.

ford00 ford00 Over the Hill Registered: 07/24/08 Posts: 1767 Loc: New Jersey	it could also be the connections on the rca out/in puts on the unit it self. I had this issue with my pioneer radio and i actually had to add a wire to the rca connection to ground. _________________________ SOLD-2000 Crown vic LX HPP-SOLD 2004 CVPI 67K miles

Carter Carter Member Registered: 10/03/08 Posts: 342 Loc: Michigan	Ok, finally took care of the whining noise. It was what all of you guessed. I put in a pair of RCA cables between the interface and the tuner box with a ground loop insulator. It now sounds crystal clear.
