Try doing a search in the forum archives. This subject has been covered previously on more than a few occasions. I would only add that you really DO need to pay attention to cable spec's when doing LOOOONG runs such as yours. Too much capacitance and the amp oscillates. Too much inductance and you have NO upper mids and treble. Any long run of wires can also act as an antenna, so you must also take this into consideration. Look for an "anti RFI" design. Sean
