Loudspeaker output simply on bulk?

Hello, have a small problem, or a question. No old Polo 86c has obviously (from work) the V. & h. right / v. & h. left LS each in row switched. e.g. blue goes from “Radio” to v.l. + , from there as blue/yellow to hi. on +, from there as brown/schw. – back to “Radio”. Now I am the type screwdriver who prefers 3 ZKD`s than 1 radio installation But I bought myself a radio extra to the car 6 years ago (with 4 LS connections) and wants to have it finally (half way right) inside. I could spare myself any amount of eclipsive fummelei under the A-Brett if I provide every LS with + (with existing cables possible), the 4 LS then the – in mass and the 4 radio outputs – also on mass. Is no mad sound system, AEG 4 x 100 W and the series – LS by Pioneer the same dimension can put in the intended accessories.
