Did you read post #73? The external amps have almost identical part numbers so the wiring might be the same in the '14. If verified, then the wiring diagrams posted here for the '12 would be the same and you could do the same upgrade.so anybody upgraded a '14 si using basically the same method as OP? i am curious as i might be trading my '13 for a '14 and am really sick of the sound. it's time to man up and upgrade either way i keep the '13 or go '14.
