Alt. noise
#1
I had the explorer for 6 months. Up until a few days ago no noise. The " whine " started after instaling an crossover. Did the ground thing. Even moved the crossover. Is there an simple inexpensive filter I can put in line? Or is the crossover just junk? Done an search and found no answers that helped.

Ya my old crossover from my old setup (before the Orion) caused noise. Through the sub, ya never knew it, but then when I upgraded the sub I tried moving the crossover to my full range speakers and it introduced some noise. So I 86'd it, it now sits in "the graveyard" at the shop.
Also, when using the cheaper loaner HU's that my stereo shop gave me while my own HU was out for service, they all gave me noise. I troubleshooted a bit, finding that if I removed the tin bracket from my dashboard to doghouse cover (it's an Astro van, under the glove box is a tin bracket connecting dash to doghouse cover), the noise reduced some, but not completely. There's noise getting in there somewhere, but I couldn't find it. Install my TOL HU again, and no more noise at all. *shrug* Must have a built in noise filter or some doodad somewhere...

Sounds like the problem is due to power draw, check to make sure the deck is getting a good 12Volt(make sure the wire supplying the deck from factory is at least as thick as the wire from the deck, same with ground). If your battery is a standard lead-acid (with caps) type, then it may need to be filled.
If the deck's remote-on wire is supplying more than 2 components it may need a relay, or it will strain the deck.
Check the vehicle's charging system to make sure it's not fried.
Next, try re-locating the crossover(this is presuming that your cables are well shielded, and considering your previous placement).

The in line isolators are a band-aid they do not fix the problem they simply overlook it. The in line jobs are indeed audible (there is no reason they shouldn’t be audible given what they are, and there should be a phase shift, a lower output since the filter consumes power, and transients will be softened).
I can’t recommend an inexpensive one but the very best don’t sound all that bad. To me the music sounds like it lost some testosterone with the filter in line. Some amplifier manufacturers forbid the use of the isolator (i.e. US Amps) since you loose the ground path in the RCA. I had a mega expensive Jensen unit and Navone (SP?) has some good ones too.

Scosch has them, I needed it in my 83 firebird, but don't in my 01 stang. It works quite well actually. I am not using it right now, so if you need a cheap one, let me know.

Well after chasing this with many ideas nothing truly worked. I just diconected the crossover and hey still had the noise. Hu... Took the head unit out and turned it on. No noise mmm double checked all head unit wiring and rewraped the wiring. Noise is gone. Thanks guys 1 of the rca's must have worked loose over time.
