Engine whine through new speakers
I've just installed a set of JBL GT5-500C's into the GTV. All good except for one thing.
There is a quiet but still audible whine from the tweeter that echoes engine speed. It doesn't sound that far off the whine you get from the fuel pump, but this is definitely emitting from the tweeter.
As for the installation: the original mid and tweeter are fed from two separate pairs of cables, one each per mid/tweeter. Both pairs of cable have the same colour code, so I assume they are the same audio feed from the stereo, and the capacitor on the tweeter filters out the low frequencies.
The new set use a crossover, so I am only using one of the two pairs which then feeds both mid and tweeter.
Whine is there even when the stereo is off and does not increase in volume with the stereo in use.
