Extra resistors included with Jehnert Flatline set

Hopeful · 08-06-2013, 09:24 AM

Anyone else bought this kit recently? Two extra resistors in the box with an instruction sheet in German. I e-mailed them and, apparently, you need to modify the crossover for the mid/tweeter if the tweeter is too loud. From the pictures in the leaflet it would appear that I should have received four resistors but I'm still waiting for a reply on that.

I would bet that this resistor "add-on" is particularly designed for the Stereo (no OEM amp) system and not applicable to others (HiFi, Logic7/HK).

I have to say these instructions, and the methodology, suck. I agree OP, the instruction clearly state that two resitors have to be replaced on ONE crossover. But then it also says they provide two resistors total....

The first sentence translates as:

"In some BMW models the frequency response of the sound system is heavily altered from the factory."

So it does seem as though this instruction sheet only applies to you if you have the base sound system (no factory tweeters).
