??? does the '92 190e have an amp...i've been wondering for a lil' while now, my friend said its should but he didnt know abouts it would be, do you know scorchie???...maybe that's why evertime i hit a bump the radio goes off and when i hit another bump it turns back on!?!?...i dont know why, i was thinking maybe a lose wire at the amp(if it has one) or maybe the amp is blown-out. any possiblities of why she might do this. also maybe it could be the antena oly opens to about 8 inches...for some reason she doesn't wanna go all the to full extension...i was thinking while she is moving up i should give her a quick pull??? or should i leave that "quick pull" to a m/b pro, because that might be the problem too...Behind the left side trunk liner. Remove the trunk liner and you can remove the amp with a couple nuts/bolts.
