Are you saying max cutout diameter? I took my vent out and it measures about 121 or 3.75" so I was going to go with a DYNAUDIO ESOTEC SYSTEM 362 as the mids have a 3.76" OD and 96mm cutout diameter.
1 Max. Ø 121
2 3 holes Ø 4 on Ø 110.9
3 Mounting hole Ø 96 (add cut-outs
I was going to do a passive set up though as I do not understand how to configure a active setup. I was looking at getting ALPINE RUX-C701 + PXA-H701 so that I could eventually go to an active setup. You think it is smart of me to just eliminate the stock HU? I need some reasurance.
What are all those wires on that buss bar in your trunk mounted to the back seats?
