so i have a 1991 Honda civic hatch that i am working on. basically had to replace everything so far and i may need a new alt. i am planning on putting some A/V stuff in there from aftermarket lights to speakers and subs. nothing huge cause i really don't care but my amp might draw 60-100 amps... should i upgrade the alternator? i don't need like two 300 amp alts, i think a 100-150 would do fine? any suggestions on what alt to get or how many amps? thanks for any information you can give me. i believe the stock one in my car puts out 50 or 60 amps.
