Hello everyone,
I wanted to see if anyone has done an alternator upgrade with any success or failure yet...? Please let me know how it turned out and where you had it done. Thanks and Happy New Year!

 

i have a 180 amp high output alternator on my 2010 Honda Fit, and the only way you can do it if on your alternator postive outpost you run two power wires, one like normal to under hood battery and the other power wire to a battery in the back connected to your amps, its the only way becuase the built in 100 amp on factory battery terminal would blow

 

Did you so this yourself. I have had my 4 12's for about 2 years and have always wanted to replace my alt.
