But it could also be the shorting of the two speaker wires somewhere between the Audio Amplifier and the speaker in question. When the speaker wires are shorted, you, for sure, lose that channel. But in some case, you would lose all 4 channels. You can check the shorting of the speaker wires/ Amp outputs by probing the speaker connectors (after removing the speaker from the connector) using an Ohm meter.
Another possibility is the broken speaker wire(s) or connection problem. Checking for broken wire is harder since you have to probe at both ends (speaker end and the Audio Amplifier end). But indirectly, you could check the DC voltage at each wire (again with the speaker taken out). At each wire, you should measure something around 6V - 8V (depending on the battery voltage. This is normally 1/2 BATTERY voltage). Broken wire has no voltage at all or some voltage out of range (13V if it is shorted to BATTERY).
Sometime it could be the radio itself is at fault (connection problem at radio side, blown one audio driver inside the radio)

As I stated in the earlier post, the hiss was reduced but it's still very noticeable by someone with an "ear" for it. I had been wanting to compare my car with a newer one ever since the "fix" came out but wasn't able to until this past Christmas. My sister bought an '07 LTZ and it has the exact same hiss as mine. So, mine is as good as it gets, I believe, which isn't saying a lot.
If you suspect you have the old amp in your car, take a look at it and describe it here. I also think the heat fins on the new amp run diagonal whereas the old amps fins ran inline with the sides of the casing. I'll go look at mine again if need be.
Good luck and keep us posted!

Does the system split the signal sent to the front speakers so that the woofer is only getting a low end signal and the tweeter is only getting a high end signal? For example, if I replaced the front 6 3/4 speakers, would they be receiving a full range signal or is it run through a crossover to split it up between the 6 3/4 and the tweeter?
1. Pulled the fuse
2. Pulled the battery
3. Tried cleaning cassette. It gets ejected like any other cassettes I tried.

Any ideas? Thanks in advance.
