I was out over labor day weekend noticed that my tower speakers shut off, figured the amp overheated due to the 100 degree weather and non-stop playing. The speakers never came back on after two days of being off so figured I burnt up the amp and sent it back to zapco. Amp is a 750.2 Reference, they called said the amp was fine but the fan was bad so i had them replace the fan and send it back.
I get the amp back plug it in, turn it on. Right off the speakers sound horrible. I flip the impedance and they get a little bit clearer. I begin to turn them up and boom nothing NO SOUND. Now i cant get any sound out of the amp. So I gave zapco a call they think its a bad speaker causing the amp to shut off or bad voice coil.
They said to test the speakers which should result in 4ohms on my volt meter. I cant get any type of resistance out of the speakers on 200 or 20k
I'm about to order another set and start replacing , i checked the wiring everything seems right.
First off this is the set up. With how they are wired.
4-6x9s Audiobahn Marine speakers wired as follows the second diagram.
Any ideas? How should i be testing these speakers?
