To start off I'm new to this and can't pinpoint what is going on, so I have a 2007 Honda Accord EX-L i4. I recently had a shop install my skar 12" sub with an 800w skar amp (I will also be adding front door speakers and rear deck speakers soon). I'm having an issue where when I play my radio up to a certain volume the two interior dome lights start to ever so slightly dim with the music when there's a lot of bass. I'm trying to figure out if it's because I didn't install a big 3 kit, if my stock alt is not enough, or both. I cannot seem to find a big 3 kit that is 100% OFC with ring terminals small enough to fit on the stock alternator power wire connection because of this plastic piece that goes around where the power wire for the alternator goes, the only real kit I could find I don't know if the 4 gauge wire is enough or not compared to using the 1/0 wire. If it's the alternator I have no idea what brand to get and exactly how to know what amp rating i need for my system. Any help with this is greatly appreciated, I've been more than stumped with this and can't figure out what to do.
