All,

I recently installed an ATOTO F7E head unit, which replaced a PO installed Kenwood single din. It works for a while, then randomly blows the dome circuit breaker under the hood, has happened twice now. First it was only slightly blown, causing a voltage drop. Next time it was a clean break.
Now, I know logic says if you just installed a new head unit... then that is your problem. If I had replaced stock, I would agree. The PO had a single DIN, old Kenwood h/u, which would randomly go into "protect mode", which as I understand indicates a fault/short either inside the h/u or the speaker system. A hard reset would take care of the error. The PO had also run the constant power input directly from the left battery with an inline 15A fuse, I took that out and used the factory circuit. Could it simply be that the new h/u draws more than the circuit should handle?
The install of the new unit was pretty clean, all unused wires are separated and insulated. Sound is good when it works, no buzzing, ground is solid on the factory location.
Common fault locations that might cause this?
V/r,
Clay
