SimonT Member 18 Member For: 16y 12d Posted 27/11/09 09:17 AM Share Posted 27/11/09 09:17 AM Yeah everything is pointing to the factory Premium sound setup as the problem. A few other installers have noted the same issue according to my installer. The thing is, it's so nicely integrated I'd rather not go to an aftermarket solution. Has anyone had and fixed the issue? Would it be worth trying to figure out how to mod the ICC to have RCA outs like the sticky? Or would the noise be sent from those outputs as well? Does anyone have an FG with Premium sound, in a Ute (no amplifier or sub) and upgraded to an amp and new speakers, and NOT had noise? Link to comment Share on other sites More sharing options...

If you are really geeky then you could put a CRO on it, that'll confirm it... Link to comment Share on other sites More sharing options...
SimonT Member 18 Member For: 16y 12d Posted 27/11/09 01:01 PM Share Posted 27/11/09 01:01 PM Earthing problem is the obvious answer yeah. Installer has tried everything though. Different earthing points, everything to the same earthing point, all the usual fixes for the obvious installation stuff-ups (which weren't made in the first place), but multiple new things were tried, all to no avail. In-line RCA ground loop isolator was tried - no difference.I'm just wondering if there are any pro installers on here who have fitted full aftermarket gear (besides the head-unit) to an FG, in particular the ute, and had a completely silent noise floor.

highside4 Member 2 Member For: 15y 5m 6d Posted 29/11/09 02:27 AM Share Posted 29/11/09 02:27 AM I have an 09 FG XR6T ute with standard 'stereo', + technolgy pack including bluetooth and ipod integration. When I first looked at the car the integration of all the parts seemed great, but when it gets down to it has really been nothing more than a headache. First couldn't get the bluetooth to work reliable with my iPhone 3GS. Installed a parrot 3200i(?) system, eventually (no thanks to Ford for their inability to help). Got it to mute the stereo, come up with 'phone'on the icc display etc. Also found stereo sound wanting so pulled the roof lining, door linings, rear lining and installed bitumen based deadener sheet and some barium mat here and there as well as alpine type R 6 1/2" coaxials in the rear (in the factory plastic speaker mounts - great fit) and same speakers in component version in the front (lots of MDF required to mount correctly). Factory speaker wires run back to a common point behind the drivers seat and into a Rockford Fosgate 3Sixty.1 processor with the output into an Alpine MRP-F600 4 channel amp fed by 4 gauge wire straight from the battery and earthed to the chassis locally. Outcome? The sound deadener is awesome. Makes everything quieter, less resonance and the car feels more 'luxury'. Doors thud shut, I can understand people on the phone even at highway speed and they can understand me. Problem is the same low level signal noise described by others here. At low listening levels (which are now possible as the interior is quieter) the background hiss is very fatiguing. So much so that I have taken to listening loud or not at all. Best reduction was by turning the amp gain right down, and running the processor gain at the minimum level to still get reasonable volume. This means you tend to run the head unit at higher volume numbers where the s/n ratio is better. Its still far from great though and you miss out on the SPL the setup is capable of. Also, the rear speakers have a shocking resonance in freq between about 400-800hz which results in some pretty ordinary sound. With the 3Sixty.1 I can (and have)equalized this somewhat as you can equalize front and rear speakers seperately. In the front this frequency band needs boosting so without a processor you need to be very careful how you set up your fader and bass levels to have any chance! Wish I could have bought a 3Sixty.2 as the extra frequency bands available in the equalizer could have helped. Might have been able to cut the hiss a bit too. I've had enough of fiddling with this stuff now so I'm just going to suck it up. Oh and I'm looking at a wiring diagram of the ICC and there is only a single line out on it which looks like a summed on for the subwoofer amp. Has plenty of 'ins'though. Hope this is of some interest to someone. Oh, and I'm just an ameteur hacker and will defer to any of the talented indivduals out there who do this for a living. My apolgies if anything I have said is just wrong - my humble opinions and thoughts only.Cheers Link to comment Share on other sites More sharing options...

BT works a treat with my cheap and nasty Samsung..Sound is good but I am waiting for one of the speakers to go 'kaboom' so I can out some better ones in there.. I don't think I'll do anything else if audible hums are going to appear and what sounds to be a pain to get rid off... Link to comment Share on other sites More sharing options...

EARTHING MUST EQUAL OR BE GREATER THEN THE POSITIVE FLOW OF CURRENT!!!something all to often forgotten also...people will run 2 gauge from the battery, but then run a 6 guage to the frame... woops... no no!Try a different amp also and see if there may be an issue within side the amp its self!(think I mentioned this before)...
