anyone ever did an alt install in their civic? anyone know if its difficult / time consuming?

Not hard at all - I installed a 170 amp alt in my civic..still have it but removed the system. You'll need to take out bottom bolt and use a wrench to get off top nut. I ran with 0 gauge from alt to battery. Also ran this on 1000 RMS/15" in 5 cube box in trunk - trust, 170 will be enough for your setup with good battery //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
