8. Crossover circuit - Speaker connection
8.1. precable crossovers - see fig. page 11.
8.2. install crossover under the dashboard. Check precise fit.
8.3. Insert subwoofer and midrange and connect all loudspeakers
(car door: midrange and subwoofer / dashboard: tweeter)
to the crossover circuit (parallel-circuit):
Notice:
You should check the polarity of all subwoofers
before connecting them to the crossover circuit
with a 9 volt battery:
pole of the crossover circuit input to of a 9 Volt battery
pole of the crossover circuit input to of a 9 Volt battery
All subwoofers must move uniformly!
Wrong polarity of a subwoofer can totally
equalize the bass sound!

3.1. unclip the plastic frame of the tweeter grill with a taper key and remove it
3.2. unscrew the screw underneath and remove the speaker’s grill
3.3. remove the original tweeter and disconnect the cable
connect the JEHNERT tweeter (1,5 - 4mm
2
)
3.4. Length of cable: up to the crossover- mount underneath the dashboard
3.5. affix the perforated sheet metal to the tweeter. Secure with washer and
hexagon head screw.
3.6. Install the tweeter with the perforated sheet metal in the original mount
and lead the speaker cable to the mount of the crossover.
.
Acoustic TIP:
adjust the tweeter in an angular position to the inner rear
view mirror (not driver’s or co-passenger’s side)

3. tweeter installation in standard mount of the dashboard
You should check the polarity of all woofers after having
connected them to the crossover circuit with a 9 volt battery
(input cable on the side of the amplifier).
Recommendation:
Install both crossovers on the passenger‘s side underneath the airbag.
*Important:
Protect the sheet bar against humidity and observe that the sheet
bar does not touch any metal parts – danger of short circuit!
