Review on The Ultimate Wiring Solution: Metra 70-7004 Turbo Wire Multi-Wire Harness by Mike Littlejohn

Had to heavily modify and trim the factory wiring harness as it is not costly for a 2005 Galant GTS with Infinity amp as the standard amp does not have a rounded RCA connector. The wiring harness I had to cut was as follows: Amplifier wire from the wiring harness next to the antenna on the stock radio: Amplifier to -PinkGround -BrownGround -Brown/White Front Left (+) -White/Blue Front Left(-) - Orange/Blue Front Right (+) - Red Front Right (-) - Green Rear Left (+) - White (will be next to Orange in the wiring) Rear Left (-) - Orange Rear Right (+) - White (will be next to Black in the Wiring) Rear Right (-) - Black I then cut the round plug off the RCA jacks and connected those RCA jacks to my cut factory wiring harness which ended up working great.
