okay so i just bought a 170 amp mechman alternator and before my voltage drop was pretty bad but since i got the 170amp alt its got even worse i dont understand what is going on. I have a hifonics brx 1100.1 and 1200.4 but the 1200.4 is only pushing a set of 6.5 component set so it really isnt useing much amps, also i have a stock batt but its only 5 months old at the most. Im also running 1/0 guage power and grounds so if anyone could help me that would be great.
