I've been having a lot of trouble with my system sub. Doing some troubleshooting yesterday, I realized that even if I just hooked up uust one of the speaker leads, either positive or negative, I was getting sound from the sub. It's not supposed to do that, right?? It seems to me that it should require both leads be connected before producing sound. I was also able to do the same thing for one of the rear deck speakers -- plug in either lead and I get sound.

Does this sound like a grounding problem?

Your input is grounded to the car some where sounds like. Would need to know more about your system to fully diagnosis.

My current setup is taking the high-level (speaker) signal from the stock amp into a Rockford Fosgate 3Sixty.2 sound processor, then from there into two Alpine amps (MRD-M605 mono and MRV-F545 4-way). My speakers are ADS 346cs components (125W) in front and Polk Momo MMC-650 coaxials (80W) in the rear deck, with an Infinity Kappa Perfect 10.1 sub in a 0.65 cu.ft sealed enclosure (Type 1). I had everything installed professionally but the sub isn't sounding right. It's all muddy and weak.

Heh, not that professional apparently

It's possible to have standing waves that can cause current to propagate down a wire without actually completing a circuit. That's why you can hook your sub up to a high power source and get sound coming out of it with only one wire.

Think about how FM radio antennas work. They are just single wires that are in the air. There is no actual completed circuit. But the enduced current flow from the radio signals in the air is real.

I could elaborate more fully but you'd need a degree in electrical engineering or physics and an intimate understanding of maxwell's equations

Funny guy.....I'll definitely let you know when I've completed my studies so I can hear the rest of this....
