OK I have 2 batteries in my truck a optima yellow top and a duralast gold, on the yellow top i have my sub amps (2 fosgate t1000.1bd) plus the car itself. and on the other one i have the power for 3 amps for highs and mids with an isolator, already did the big 3. Well the question is would it make any diffrence if i hook up all the system to the second battery mainly cause the power wire dosnt reach from the optima. the two batteries are connected together so if you know please help. GRACIAS
