[QUOTE="BCotrell, post: 8701529, member: 666314"] Is that amperage rating 180 for 700 rpms? The newer Subarus tends to be on the tail of gutless unless you have their teenager cars (for the sake of efficiency they promote) which correlated to generally lower idle rpm than a ho alternator may be designed for. anyways, if you’re listening to the stereo with engine on disregard posts nerding out on alt/battery stance...car is on alternator is providing more than enough amperage to feed a 1700 watt amp musically -Are Big 3 grounds all good? What wire you use? -at the amp what is the voltage (Drop) from baseline(14 ish with car on) that you’re seeing on when you have music up and car is on? [/QUOTE]
