you must not have searched that well. been covered a bunch of times. see my sig for pics. i just uncovered the wiring between the doors from electrical tape to coldshrink and it lots even better and even cleaner. heck, i was at home depot the other day and even took a pic of the grommets. they are right in the electrical section near the wire by the foot section. package of 3 rubber grommets. 1" each i slit the grommets to maneuver them into the hole better. start with a pilot hole. i used 2 unibits - 1/2" first then the 1" bit.
i didnt do the rear doors cuz i'm not going to run a major rear fill. just some dropins powered by hu's rear channels.
