hi guys,,,hope you can help. left speaker is not working(dead). getting something from tweeter, only just. cannot find anything resembling a basic crossover unit. any ideas.
What head unit do you have?
the oem Toyota 58806.
I suspect that the wiring on the door loom may be damaged. Rigging up a direct feed from the socket in the passenger foot well would confirm or eliminate this.
I assume you've already examined the balance setting on the head unit?
yup checked balance. I have new speakers to put in, but suspect the wiring or h/u. was going to use existing wiring. I am getting a little from the tweeter only.
tweeter + woofer use same wires.
the tweeter is connected in parallel with an in-line capacitor.
easy way to test:-
door card off , unplug both stock speakers and temp wire up any speaker.
if nothing -
buy replacement h/u, someone here is bound to have a stock one for real cheap.
replace. still not working then run new wire time.
long way ,cheaper if you have a multimeter.
if fitting new speakers and have both door cards off just swap speakers
check woofer diaphragm still moves without catching.
check for shorts - unplug both stock speakers and measure the loom.
should read open circuit, but may show as just a high resistance.
measure speakers, cant remember but 2,4 or 8 ohms. not 0.
if speakers measure okay you'll have to remove h/u to test wires.
plug speakers back in and measure the corresponding colours on the h/u lead.should get speaker resistance.
Will be taking the other card off tomorrow. Will try the working speaker on it and take it from there.
tried another speaker,,,,worked fine. at least wires are ok. will be fitting new speakers later. cheers guys.
