hey guys its been a while since I have been here, but have recently gotten back into the game again. So I finally got the time to to do the big 3 on my 2005 Altima SE-R in order to get rid of the light dimming issue. The wiring did improve the voltage drops but I am still getting what I think is a big voltage drop when my Subs hit hard. My alternator at idle puts out around 14.14 volts. I run a parrot asteroid head unit with stock factory bose speakers and 2 8" JL W3 powered by a JL 500/1 amplifier. I decided to check how much power my subs are using when my alternator at idles drops to around 13.4 volts . I used a crappy tire digital multi meter and clamp meter for my test. I also used a 40 hz test tone off of youtube and got around 500 - 503 watts. Anyone think its normal for my voltage to drop that much while using 500 watts?

Thanks
