Connectin Aftermarket HU wire harness

Ok so im looking here at my alpine ixa-w404 and my scosche wire harness, the harness has wires for the left right front and rear speakers, but im running all new wire from my amp to my speakers, so my question is do i still connect these wires? i mean im having the signal being brought from the rca cable to the amp and from the amp to the speakers so is this correct? do i just terminate these eight wires? or connect them and see what happens?

 

THIS.

 

so this harness is really just for the power correct? so out of the ENTIRE harness im using about four wires? thats crazy

 

yup, my HU harness pretty much is just my power, ground, constant, and the parking brake bypass. Everything else is taped off.

 

parking brake bypass? i guess thats for watchin movies?

 

that and to be able to control my navi while in motion. Mine has a gyro inside so it senses movement.

 

oh ok yeah mine is just the alpine double din media station ... no navi or movie capability, i have no need for either

 

ah.. well just hook up all the wires you need except for the speaker leads, and your set.

 

Sweet because it came with a second harness for the rears and I just thought id ask if I really needed these but thanks for the input you guys

 

Not particularly crazy if you're running all new wires for the speakers. Some might consider it crazy to even bother with the harness if you're running all the other wires.

 

True but im not splicing into the factory wires
