I have a 2008 Hyundai Elantra. The factory alternator is 90 amps. I am currently using a JL Audio XD600/1 and XD400/4 amplifiers. Less than 1000wrms. The factory alt does surprisingly well with this setup. voltage rarely goes below 13.5v above 1500 engine rpms. I have a DC Audio 2.0K that I will hopefully get back from repair soon.
I have a D3400 starting battery, big 3 in 1/0, 1/0 ground from alternator to battery, 1/0 pos to trunk, 1/0 neg to trunk. All 1/0 is Stinger HPM.
I recently installed my brand new Excessive Amperage 200a alternator. I am experiencing crazy voltage flucaution. the voltage dips down into the 12's then sky rockets into the high 15's. It doesnt do this on all music though. Tracks that have long bass notes hold steady in the 14's.
Do you guys have any idea why my voltage is fluctuating so badly since installing the Excessive Amperage alt?
