new audio system through stock amplifier not "booming" please help!

In the last picture, it looks like your inputs are on the bottom connector (smaller wires) and the outputs are on the upper connector, along with the power wires. This is what I hoped to see

Up to 2000 models only

Front Right
+ {Violet with Red stripe} to {Red}
- (Common) {Brown with Black stripe} to {Red with Brown stripe}

Front Left
+ {Green with Red stripe} to {Yellow}
- (Common) {Brown with Black stripe} to {Yellow with Brown stripe}

Door Right
+ {Red with Black stripe} to {Violet}
- (Common) {Brown with Black stripe} to {Brown with Violet stripe}

Door Left
+ {Yellow with Red stripe} to {Green}
- (Common) {Brown with Black stripe} to {Brown with Green stripe}

If everything works, then you can then toss the stock amp.
