I've had this alternator in my 2017 Subaru outback for close to a year now without any issues. My power needs water for a 1500w aftermarket audio system. The strange thing was with the OEM alternator my lights didn't dim but, my engine RPM would dance to the bass kick, lol. Never experienced that before.

Power bastards alternator was plug and play as described. No more rpm dance, no added noise, quiet, and smooth operation. I had already done the "BIG 4" and a new serpentine belt went on at the same time as the PB alternator.

Also I soon found out that most off not all newer vehicles have a regulated voltage power supply now, so I purchased a bypass module from another company that allows 14.5v-14.8v continuously to the system.

Very happy with my purchase. I will be back for my next project car
