ive had a sub put in by a ICE shop and they said they used a high-low converter
now my mate was in the back the other day and said nothing is coming out of the rear speakers
doing a bit of research i read that some people cut the rear speaker wires to use the high low converter
i tried to remove the glove box and tried about 50 allen keys and none fit perfectly
is there a special size? or tool?
i wanted to look at how he did it
