i am using 3 way audiopipes in the front i switched them two days ago. i had the r types 2 way in there. i know the r types have the jumper you are talking about the audiopipes dont unfortunately but i have another idea here. Im thinking about mounting the R type tweeters in the back and using the with the corresponding xo.
Do the x-overs have any switches in them? Sometimes there will be a level switch for the tweeters. Mine have 0, -1.5, -3 and -5. Yours may be set too low. I don't know your exact model speakers, but one of the Type R component sets says this "2-way crossover with 6-step tweeter level adjustment" So check those.
