I need to run wiring for my home entertainment setup thru an exterior wall.
This is obviously a load bearing wall and I assume that it's 2x6 beams, I
am not sure what the code is in NJ. This is the first floor of a two
story house and I wood need to drill holes in approximately 3 beems to go
accross a four foot span. I would appreciate any advice on if I can drill
or notch the beams and to what extent. Also these beams are above a
window, so I would also have a header beam to contend with. I appreciate
all advice.

Thanks;

Drill the smallest holes possible in the center of any beam. Check out
the super extra long drill bits available at box stores like Lowes. Not
likely that the new holes would have any significant effect on beam
strength. HTH
