Hi,

I gave up and took it to a shop for troubleshooting. Apparently, it was the fuse at the hood. It doesnt look blown, but it was. So they replaced it and charged me $20 CND for the fuse and troubleshooting h:

The amps keep shutting down sometimes, so I am going to switch to ANL fuse and get rid of my 3rd amp (Hifonics for rear speakers). And will use the Zapco 50x4 to power the interior speakers. Much simpler system and less headaches of course.

I also bought Boston Acoustics S65 speakers (6-3/4 coaxial). Hopefully they will sound great at the front
