Wonder if anyone would be kind enough to lend some advice...
I will be fitting some Infinity Kappa's to my Astra soon which will be powered off of a Rockford Fosgate 501x amp and I have a bit of a dilemma.
As you well know, the door cable connectors won't allow a new speaker wire to be passed from the car chassis to the door, therefore replacing the standard cabling will be a problem.
Would you advise:
1. Drilling this connector to pass a new cable through to the speakers or
2. Taking the new speaker cable from the amp to the ISO connector at the back of the headunit and using the existing car speaker cabling from the ISO to the speakers?
Do you think that you'd notice much of a difference if the new cable were used to power the speakers as opposed to using the car cabling?
