[QUOTE="Spyder_1974, post: 8741606, member: 682720"] Hello so basically I have a on my 1974 Pontiac my issues include: - Alternator whine higher frequency only comes in through my rear speakers When I unplug my rcas the alternator wine stops not sure if this indicates anything. - bumps from sub when breaking -220a power basterds alternator does not keep the voltage to the rear battery (I have two) and the alt is brand new between the front of the car and the rear when playing bass it shuts off from low voltage unless if it is fully charged then you have about 20 min of playtime while driving. while the car is running 14.4v at the front battery and never see over 13 at the rear as soon as you pull the voltage it drops to close to 11.8 and soon runs out of battery at the rear. is this because I have 0 gauge CCA instead of ofc the wire has to be run about 25ft because the car is a boat. My system includes: all 0 gauge wire 220 amp power bastards alternator 2k skar audio amp skar zvx 18 And rear Rockford Fosgate speakers that have the alternator wine are powered off of another amp in the trunk mtx amp [/QUOTE]
