Speaker vs. Amp problem?
#3
Here's the details: Replaced OEM HU with another used OEM HU and upon checking functionality of balance & fade discovered garbled noise coming from driver side rear speaker. I'm not an audio guy, but understand that the Bose speakers are individually amplified. Wondering whether I need to replace the speaker, the amp, or both - and how to tell the difference.
Again, thanks.

Thanks for the help!

well, if you have a multimeter handy you can check the resistance of the speaker to see if it's still ok. take the two leads from the multimeter and touch it to the terminals on the speaker. i forgot whats the load, but if i recall it's somewhere around 1 ohm.

so, per your recommendation, if I check the resistance of the speaker (while stereo operating I presume) and I see appropriate reading (1-2 Ohm, right?), then that tells me that the Amp is OK - sending appropriate signal to speaker - but speaker is blown?
I was figuring one thing I can do is attach any speaker to the lead for long enough to check and see that the amp is working ok. It won't be 2 Ohm speaker, but if I get sound (at lower volume, I know), that should indicate that the Amp is OK and it's a speaker problem, wouldn't it?

but if the resistance of the speaker checks out, more than likely it's the amp's (or that HU you just swapped in) fault.
