MOUNTING:

Mount the speakers in the door or in the dashboard of your car. Normally they will fit in the cars original mounting hole. If possible reinforce with a baffle of MDF-board or similar. An installation high up on the door side is to be prefered. An alternative installation is in so called kick panels down on each side of the floor with the speakers facing up- and inwards towards the listener. An installation of the tweeter close to the bass/mid element is to be prefered. The tweeter can also be installed on the dash-board, or recessed in the door with the accessories in the tweeter box. It is important to fasten the speakers properly in order to avoid bad sound and rattling. The filters included with the speakers must also be fastened properly to avoid rattling. Dont place them close to the cars internal wiring, this can cause interference. Make sure the cables dont get jammed causing a short circuit to ground. This can damage the amplifier circuits. The speaker grilles are mounted in the plastic speaker frame by the use of the rubber coumpound thats included in the packing. Spread the compound even in the frame. The sealing strip coming with the kit can be used for improved sealing between the bass element and the mounting surface. The tweeter installation is described in the instruction sheet coming with the tweeters.
Speaker connection and tweeter level select:
The filters coming with the system should be connected with the respective speaker element as in the drawing. Select tweeter level by moving the jumper inside the filter box between high / low. Make your own tests for best result. Sometimes the midrange can be improved by phase reversing the tweeter. Try it and judge yourself.
NOTE! The filters must be used. If the tweeters are connected without filter they will be damaged and the sound reproduction becomes bad.

CONNECTION:

A 2-way system connected to one channel. The other channel is connected in the same way. Tweeter level select: By moving the jumper inside the filter box the tweeter level can be selected high / low. Tweeter +

SPEAKER PHASING

To be sure to have the correct speaker polarity (phase) you can check this by using a 1,5 Volt battery. (Not on the tweeter). Connect a cable from the battery plus(+) to the speaker plus, and a cable from the battery minus (-) to the speaker minus. If the speakers are correctly connected the speaker cone should move outwards on both right and left channel. This check must be made on the cables going from the speakers, to the output terminals of your car stereo or amplifier.

SURFACE MOUNTING:
