    Depends on the amp, but if the terminals or wires touch chassis ground, then either the amp will cut out, you could get engine whine or other strange popping/crackling noises, or the amp will short out and go into permanent protect.

    In a headunit, the amp will just cut out which is basically protecting it from destruction.

    Durwood,
    The Infinity speakers will work fine with all aftermarket radios. Of course, before we built these things, we tested OE radios and aftermarket radios driving them and nothing failed. Furthermore, in the 3 years that we've been selling them, we haven't had any reports of failed head units as a result of driving these speakers.

    THe impedance of a speaker is more complex than the simple "nominal" rating suggests. Furthermore, once the speakers are installed in the car (often using the factory 18-22 gauge wiring) the impedance the radio "sees" is higher than the DCR of the speakers, which is c. 2.7 ohms. Additionally, once the speaker has been playing for a few seconds, the voice coils gets hot and the impedance rises. This is the case with all speakers.

    Infinity "2-ohm" speakers are suitable for connection to all radios.

    The reason why your fadeand balance controls are messed up is because circuit city uses so called "smart"-harnesses for the radio installations. What most likely happened is they used a sony harness instead of a JVC harness. Those two have the same plug configuration but different pin assignments on the speakers.

    I've seen plenty of people try to use 2 ohm loads running off an aftermarket radio and it's not healthy for the radio=lots of heat. I have never ever seen an alpine/kenwood/pioneer/blaupukt/etc etc radio say it's ok to use anything lower than 4 ohms.

    Most chip amps are rated for the lowest of a 4 ohm load, and while I understand a speaker is more complex than pure resistive, it's asking for trouble in my eyes, unless your goal is to sell more amplifiers as well. I CAN see it working for people who want to replace bose/infinity/jbl stock speakers since they are more compatible.

    If people's headunits burn up/amplifier circuits die an early death as a result of infinity's claims it's ok to use them, does Harman plan on covering customer's headunits?

    We stand behind these speakers 100%. As I wrote earlier, we've never had a radio fail driving these speakers.

    That's fine, but does the radio get warmer/hotter than usual-i.e. when running a 4 ohm speaker? That's what I want to know. I know you guys know what you are doing, but the average consumer might abuse their equipment a little more if you know what I mean.

    I can say that my cds are coming out pretty hot from my radio. Thanks for all of the input, I haven't had time to check everything out yet but will soon. Hopefully I don;t have to change the wiring harness because it is a pain in the @$$ in a 2000 honda civic, having to pull out the glove box and panel under the driver's side to be able to pull the radio out.
