I don't want to hijack this post, but I have a question too. My amp just quit on me the other day. It's a JBL P80.4. The manual says "the total impedance of the speaker system connected to the amplifier in bridged mode must be at least 4 ohms in bridged mode".
In each door I had a 4 ohm mid and an 8 ohm tweet connected in parallel and bridged to the amp. They add like resistors don't they so 1/4 + 1/8 = 1/R. R would equall 2.666. When I measured the resistance through the setup with the multimeter I got something like 4.6.
Did I fry my amp, or was the amp bad or am is my understanding of this flawed, and is there no way to run my amp bridged with these speakers?
Actually, I don't think that is quite right. You mids and tweets weren't wired in parallel, the crossover you installed would take away the parallel effects. What you ended up with was a 4 ohm load under 2000hz and an 8 ohm load above it.
You should have been ok with the setup. If I understand your setup correctly, you bridged the amp to two channel mode, correct? This should be sending 160w to each of the component sets. 160w under 2000hz, 80w over 2000hz.
