i have alpine 9835 which is 26x4rms and speakers are 5x7 in back 6 1/2 on doors and 3 1/2 in dash i just installed the deck myself and from what it looks like the shop that installed my deck before ran the wires from the speakers in the dash into the wires comming from the doors so that can all fit into the deck is this right or is there a better way?
