I recently purchased this thing.

Now, the problem that I have is that I am getting a wicked distortion from the thing no matter how well I ground the line. So far I have grounded to the cigarette lighter as well as directly into the head unit. The ting that strikes me as odd is the ground seems to be making no difference in the least. In fact, I can have the ground completely disconnected from anything and it works the exact same way.

Any ideas?

Check your alternator. It's either that or bandwidth related.

Try grounding it to something connected to the chassis.

Run a wire out to the engine if you have to.

At least to see if that is the problem.

Check your blinker fluid.

Interference from something else that is poorly grounded.

If it works shitty when it isn't powered and works shitty when it is powered, that kind of says the problem isn't power supply oriented. It could be blown, but let's try a few things;

** try dropping your ipod output to about 50% or less.

** Also, try using the other modulation freq. and of course retune the player.

I hate these things because they have a built in limiter that color's the sound. If slammed hard (high input gain stage), it will make your music sound real shitty.

I hate using these types of things.

I'd just replace the factory radio with an aftermarket.

You're gonna get better sound anyway.

I did. I have a 2005 Ford Five Hundred. It had a 6-disc MP3 CD player.

Sounded like shit. I bought a JVC HD radio/CD from Best Buy for $90.

Sound is 100% better. It has a built-in 3.5mm aux. input.

Are all connections taped to prevent the RCA's and antenna connections from touching metal?


If so, it is probably the following:

1. Gain is set way too high.

2. It's transmitting on a slightly different frequency than advertised. Think of it as a "half-step" between frequencies.

3. Interference from another station.

4. You bought a pile of shit.


Purchase one of these along with the proper cig outlet: http://www.amazon.com/0-5-Fail-Safe-Long-Range-Transmitter/dp/B003FO4UHW/ref=sr_1_1?s=electronics&ie=UTF8&qid=1344950309&sr=1-1&keywords=FM+transmitter

The Whole House transmitter has 1/1000th the power that this has. :)
