While I've only installed speakers and head units before (never an amplifier), I'm going to install a 4 channel amplifier in the trunk and 4 new speakers myself this weekend.

My question is this: with 2 pairs of line-outs from the head unit, a power wire for the amplifier, and speaker wires to the front speakers, where do you run all of these wires? Do you have to seperate them or run them all in one bundle?

Also, for anyone who has already performed this install, anything I should be on guard about? Thanks a lot for your help.
