9.2. Our Tip: If the panel cannot be pressed on completely at some points. . .

Cause: the special form at these points and the resulting differences inmaterial cross section of the grill.

Solution: the distance can be levelled out with spacers 3 under theVelcro disc.(Spacers included with the screw kit)

9.1. Precisely align and carefully press grill into the Velcro fasteners.

The Velcro fastener makes a crackling sound when it is closed correctly.

1.1. roll down window completely

2.1. tweeter installation on the A-pillar:2.1.1. Lead the tweeter cable throgh the opening in the mounting bowl and lengthen it with the speaker cable (1,5 - 4 mm2). Measure the cable length up to the mount of the crossover under the dashboard (see page 9)

2.1.2. place the tweeter bowl directly above the original speaker grill - parallel to the front glas:

for acoustical reasons the tweeter must radiate parallel to the front glass and has not to be directed to the hearer!

Affix the mounting bowl with a sheet metal screw 3,9x13 to the A-pillar. Insert tweeter and fasten it with a bajonet socket.

2.2. midrange installation in the dashboard:2.2.1. pry out the speaker grill and remove the original speaker.

2.2.2. connect the JEHNERT-midrange with a speaker cable (1,5 - 4 mm2) Lead the cable to the mount of the crossover in the dashboard (page 9)

2.2.3. insert the midrange with installation installation ring into the original mount so thhat the fastening cover plates on the midrange match the original fastening points. Fasten with original screws.

IMPORTANT:Tweeter-position radiateparallel to the front glas !

3. Panel alignment

For doorlinings with ventilation flap:

Some models are equipped with a ventilation flap on the below part of the door lining.It must absolutely be sealed or closed!

3.1. Place the door lining on a plane surface.

3.2. Dismount the loudspeakers attached to the panel for transport protection. Retain the screws for later assembly.

3.3. Place the panel without loudspeakers on the door lining and align it:Align the upper edge of the panel directly on the dept under the

door handle.

Only precise alignment of the panel with the door liningwarrants optimal fit.

8.2. Recommendation crossover installation: on option under the dashboard

IMPORTANT: Do not install the crossover immediately next to electrical equimpent

8.3. Insert subwoofer and connect all loudspeakers to the crossover circuit with the included standard cables for subwoofer to the crossover circuit: parallel wiring see diagram on page 11.

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


All subwoofers must move uniformly!

Wrong polarity of a subwoofer can totally equalize the bass sound!

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

3,9 x 25

1. use the precisely aligned panel as template in order to mark fastening points 1- 7:• mark the fastening points 1-3_ premounted in the panel: pressing the panel to the door lining leaves visible impressions of the screws

• marking of fixing points 4-7: use a thin awl to set the marks on the door-lining

TIP to mark angular fastening points 6+7:put in a little bit of packing tape to this position. Measure up the angular position.

Mark panel edge and angular position on the tape.

2. draw the speakers’ cut-outs onto the door-lining.

3. take away the door build. cut out the speakers’ outlines marked by means of a compass saw

4. Drill the holes for the screws according to the marks set before. Use a 6mm drill. (fastening point 1 = 10mm)

5. place the door panel precise again and do the panel fastening in in exactly follow succession:

fastening from the doorlining - backside

1. fastening points 1-3 secure with washers and nuts

(fig. see page 5)

2. fastening points 6+7 screw in the metal-screws 3,9 x 25 into the angular fastening and secure with sheet metal nuts ø 3,9 mm.

fastening points 4+5 fromdoorlining - frontside:screw in both M4x 60 Screws

and secure with washers and nuts

All cutting edges of the panel must fit to the door lining snuglyall around without gap

7. installation of the door-lining onto the the car doors

7.1. Check up length of the screws and bolts:

in order to prevent damages of mechanic parts of the car doors, please check once again the length of all bolts and screws on the back side of the door lining! No touch with any mechanic parts of the car doors ! (please shorten if necessary).

7.2. put the door-lining into the upper sealing of the car door tip: grease the upper door sealing with a residue-free lubricant before

7.3. fit it in contrary order of succession as described on page no. 3

7.4. carefully screw in the metal screws 8-12 through the door panel and the door lining to the door metal.

IMPORTANT: Do not screw in the self cutting metal screws too tight - it deforms the doormetal and affects the normal function of the door mechanic!

fastening point 8-11: metal screw 5,0 x 80 12: metal screw 5,0 x 90

4. Handling of door lining / Panel installation - Fastening

fastening points 8 - 12 : no pre-drilling fastening with metal screws has to be done directly if installing the the complete doorling onto the car door (see page 9)

5. Speaker cables / Preparation of the car doors

5.1. Installation speaker cables 5.1.1. Lead 1 speaker cable (1,5 - 4 mm2) from the amplifier to the crossover under the dashboord.

5.1.2. Lead 1 speaker cable (1,5 - 4 mm2) from the crossover into the car door (see wiring diagram page 11)

5.2. IMPORTANT! Preparation of the car doors:

5.2.1. remove the original insulation material (foil) completely!

5.2.2. in order to protect the speakers against humidity close all cut-outs / depts on the inner door metal with tar mats or similar insulation material.

5.2.3. to avoic vibration noise tighten all original fastening screws on the inner door metal.

5.2.4. please observe that the speaker cables are not squeezed by any mechanic parts (window contrrol etc.)

5.2.5. IMPORTANT CONTROL: hold the door lining with the panel to the car door and check the following at the 1. speaker cut-out (see fig.):

• the factory installed clipped cable has to be displaced downward instead of the 1 st woofer in the panel.

• if need be, knock the door metal internally on this part - the woofer in the panel must not be in contact with the door metal.

IMPORTANT: insulate the car door - see description on page 8

IMPORTANT CHECK(only for the 1st woofer installation)

displace the originalclipped cable downwardand slightly knock thedoor metal internally


6. insulation of the door lining

Important tip: the use of 4x160mm mid-woofer /side may cause vibrations which lead to annoying rattle noises in the car door

some helpful tips:• use our self-adhesive insulation fleece (art.no.: 27000) or a foam material for the backside of the door lining (see fig. above) or

• stabilize the backside of the door lining by means of a special material(Glass Fibre Filler or stiffening material)

Important: keep the cut-outs for the door-airbags and speakers open• affix the *backside of the inner door metal with self-adhesive asphalt mats (see fig. * )

• by knocking on the car door, vibrations caused by mechanic parts (e.g. Bowden pull wire etc. ) and wiring harness may be found out. Cover these parts with foamed material, felt or something like that

• cut off overlapping cable tie (rattle noise)

• adhere felt or foamed material under the original wiring harness
