Colin - STAPUFT Posted August 20, 2009 Report Share Posted August 20, 2009 If you were planning on doing the Alternator anyway, I would do that first. This is coming from someone who pretty much did his system backwards from what he should have. I did my stereo first, and then after the fact- am having to go back with my electrical. I am going to be ordering my MechMan alternator very very soon. So- speaking from experience: I would do the proper Alt upgrade, upgrade your power/ground/charging wires (big 3), then hook up the system. Then if you find that you need an extra battery in the back, then you can add that later.
