So you want to run the front speakers from the headunit and the rears from the amp? Why are you using 6x9's in the door cards? Can you not amp the whole system? Or better still run the fronts from the headunit and use the amp to run a sub.
That is the plan yes...well that's what I have been running but just poorly...its not really a 'door' card as mines a 3dr.
So are you suggesting running nothing from the HU but run 4 speakers 2 6x9s and 2 tweeters from the Amp?
I used to have a sub but I need the boot space, so until I do a real boot build and put the sub in the spare wheel well then I'm going without.
