OK all installed (kind of), sounds awesome by the way- I'd recommend the 4 channel install, it rocks!. All i have left todo is build/get something for my 4 channel amp (nothing to attach it to).
Number one hassle was putting the radio face plate back on, requires 2 people, one to hold it, another to push the pins down.
Anyway, thanks everyone for the help (super thanks to our Steve). Soon as I've mounted the 350.4 i'll post pics. Top amp installing amusement, first time I've wired anything (car will probably explode tomorrow
).
