Hello everyone,

I am going to be running an ED Nine.5 in my 2011 civic si and wanted to know what you guys thought about electrical upgrades. I have my big 3 almost done (0 gauge) the stock wire under the hood was a joke (looks like 8 gauge). I ran 1 run of 0 gauge to the trunk already. Stock battery, stock 110 amp alternator. I don’t know how efficient the nine.5 is, don’t know if it is class a/b or d, couldn’t find anything on website. Does anyone thing an alternator upgrade or battery upgrade is needed? I have heard stock electrical on these cars is weak, the stock wire from alternator and ground is a testament to that. I’m not exactly running big power here but figured I would see what you guys thought.

Thanks
