I have a 150a Alt in my '92 Legacy. Idk for sure what Alt it had in it when I purchased it. Alt started going out, I'm sure the audio setup I had at tge time hdlped her along. So I got a new one from O'Reillys. Never bothered to read what amp it was. Just slapped her in. Noticed tho, that with the freshy in, headlights were still dimming a bit when I was bumpin. Capacitors aren't my thing. I had 3farad Cap installed previously. Headlights dont dim, but the Alt still has to charge it. Anyway. So i started getting into Alt research. High Output Altenators, Dual alternators, Xtra Batt, Batt Banks, Lithium etc etc. Which inevitably led me to call and ask what amperage I had bought from O'Reilly's. They said 70a. I looked around the ol' interweb and saw 220a Alts in Subaru's, 250a and even 270a. None that high for my car. The highest I found was 150a. I got it. Extra batt in the back floorboard between the seats. Optima YellowTop under the hood. All 1/0 Welding Wire running the system. Which is 2 EVL12's in a 4th order bp. 1 RP2K.1 amp. 4 6.5's. 2 Kicker 2 Pioneer. JVC HU. Im still pulling 200+ Amps in just the system alone. I'd guess the car is pulling +/- 50a? So im always drawing on my batteries. My Alt is always behind the system. Trying to keep up. So I'm interested in adding that brand new 70a to the mix. So....? Fab a bracket, get a longer belt, put it where you want. Replace AC stuff with the Alt?
