Well the only wire that have not been changed is the alternator positive to battery positive and its the hardest one because its hided and wired to a fuse block . And the voltage drop its on the battery and on the amp. Example a big boom at high volume can drop voltage to 9 Volt in 1 second (While the car is running).

then leave this as it is and run another like a 4g or a0g from alternator to bat., make sure it's not fused or you will have the same problems.
