I have a Rockford Fosgate 250 prime 4 channel amplifier and I'm getting a whine every time I accelerate and even when I idle I hate it! I also noticed with that the shop used 2 rca cables (left and right) from the stock head unit and created 2 Y's to plug in the the 4 channel rca's on the amplifier thus making 4 connections at the end ( 2 left 2 right). Some of my music sounds like I'm missing drums or guitar or what ever cuz jt sounds blank and u can hear the instruments ever so slightly and I feel it's because they didn't utilize the rear wiring and only tapped into the front. Am I right?

Is the amplifier bridged on the front speakers, or connected to all four?
Either way, this issue is typically a ground issue. Can you see, and post a picture of how it is grounded?

Take the truck back to the shop that did the work. Engine noise is typically a bad ground like mentioned above, but regardless...engine whine is never acceptable and the shop should fix no questions asked

Bad ground, cheap rca's running to close to the power wire. First two things I'd check!
Of course, if I paid for an install, they would be figuring that out.
And your rca's should be split front/rear, not left/right.

Bad ground is correct but cheap rca's and running close to the power wire is a myth. Even cheap RCA's are made of twisted wire for rejecting noise. If it was me doing the install I would have them split left and right if it is the base stereo as those are full range channels.

bad ground for the hum noise.
as far as missing music from songs, does this amp have built in crossovers? most do these days. See where they are set at. The high's could be set too high, the same with the sub.
