Installing aftermarket HU

[geez85]

Hey Guys,

I waiting for my new HU to arrive (Pioneer P3200dvd) and just doing some research on how to install it but wanted to confirm one thing. Ive already got the aftermarket speakers and amp installed.
Question is do i need to connect the speaker wires or do i leave them disconnected and just connect the RCA since the speakers are connected to the amp?

if al ur speakers are connected to the amp dont disconnect the speaker wires and run the rcas to the amp. btw dont remove those speaker cables cause if u do plan on selling the car ull have to run the back to put stockies in

you run the rca's from the hu to the amp. and speaker wire from the amp to the speakers. leave the old speaker wire alone. you don't need it.
